Out and about again today. Stopped in one of the local car parks and grabbed a couple of photos.   These cars really do have quite some road presence. Can't really think of many things which compete in that regard other than the like of Rollers, Tatra T-603... Really does suit the estate body as well I think, so many estates look clunky or out of balance compared to their saloon or hatchback variants, whereas this shape just works for me.  Gave the interior plastics a really quick wipe down this afternoon with some vinyl & rubber care solution. Never ceases to amaze me how much life that alone can bring back to the interior of a car. They really were quite dull and chalky.     The interior really is a pleasant place to be. Even in spite of a partly collapsed driver's seat base. While I had the stuff out, gave a few of the exterior plastics a quick wipe down as well - totally forgetting the grey bit of the radiator grill. Derp.  Noticed while doing this that there's quite a bit of condensation in the nearside headlight.  Given how warm it currently is have just popped the rear cover off it, hoping the weather will dry it out for me. I'll have a closer look to see if I can see any evidence of where water may have got in at a later date.  Courtesy of a local independent locksmith we now have a non manky set of keys, the tatty ones it came with have been relegated to the spares drawer. They both worked fine but the ignition key had long since lost the plastic handle bit so was really awkward to use. Has reminded me that I still need to get a spare made up for the van, as they have the right blanks will run by there again tomorrow to get one made. Not having a full set of spare keys makes me really uncomfortable... especially as I've locked them in it once already (and had to break in via the gas locker and unbolt the sink from underneath to gain access!). |

Rocker cover gasket arrived this morning so should be able to look at getting the valve clearances set and the top end at least something resembling oil tight soon. Then will get an oil and filter change done. I'm looking forward to that as I'd really like it to stop sounding like an 80s 1.1 Fiesta.  Fuel filter was done not massively long ago, but I don't know precisely when...so I'd like to get it on the service log. I'm seriously tempted to fit the old fuel pump from my Saab as the one currently on here makes an utterly horrendous, piercing whine. Just need to look up the specs for the two to make sure they're the same - but my gut feeling is that they will be. Normally I'd have already done the oil & filter change, but I'm holding off until I've done the valve clearances and have cleaned up the remains of the old petrified rocker cover gasket that will no doubt be stuck to the head. I'm bound to get some crud washed down to the sump when I do that, and I'd rather do that immediately before rather than right after an oil change. One thing I noticed a day or two ago was that the tailpipe was only sitting in one of the rear hangers.  Upon reattaching this errant hanger it immediately became apparent *why* it was detached as a horrible rattling buzz reverberated through the car. The unmistakable noise of an exhaust pipe touching the underbody. Right here.  The reason that one hanger was removed was because they were too short. A simple fix at least by sticking a couple of slightly longer (50mm diameter) hangers in there instead.  While in that corner I investigated the non functional reversing light. Just a case of dirty contacts, after a quick clean it was back in action - though it needs a good clean and ideally a new lens.  As I had hoped the condensation in the nearside headlight has cleared up completely.  Annoyingly I then spotted there's similar damp in the offside one...it will get the same treatment next week.  Was interested to discover that the inner two elements in the headlights aren't actually used for main beam (as on the Ford Sierra to name one car with a visually similar structure to the lights) but appear to be front fog or driving lights. Really need to track down an English PDF of the handbook! |

Love this - a proper estate and a real survivor. If you ever thought about making it quicker, I could just mention that rotten SLK 230Ks have never been cheaper. I'd imagine that it wouldn't be too hard to drop one in  Instant supercharged TE  |

I'd imagine that it wouldn't be too hard to drop one in Instant supercharged TE In all honesty I'm really surprised by the turn of pace this car has exactly as it is. I was expecting performance very much on par with my Saab from a few years ago, but this car *feels* like she's got more poke. I'm quite surprised how nippy she feels to be honest as on paper 134bhp looks pretty modest in such a big old barge. Fun though bolting things like superchargers on may sound, the relative mechanical simplicity of this car was one of the big draws for me so she will be staying standard for the most part. |

Couple of things done today...first of which you likely won't be able to see on camera - cleaning the inside and outside of the windscreen. It's nice being able to see where I'm going now. Inside was particularly bad with a really thick, greasy coating on it.  Had a nose around under the bonnet with a view to seeing what I need to move to get the rocker cover off. Doesn't look like it should be too bad. Found a nut and a few washers so have replaced the missing nut on the exhaust manifold.  Couldn't actually see or hear any sign of it blowing there, but at least I know it's bolted up properly now. While the exhaust manifold doesn't seem to be leaking, the rocker cover definitely is. Oil everywhere.  I am seriously looking forward to cleaning this engine bay. Not only will it be immensely satisfying, but it will be really nice to not get covered in black grime every time I so much as walk within ten feet of it. Realised this afternoon that I'm going to need to spend more money before the proper cleaning can start though as my pressure washer died a couple of months ago. This shows that she really needs a good clean outside as well as under the bonnet.  Sadly my pressure washer died a couple of months ago...so I need to replace that sooner than later. Spotted something that needed immediate attention today...this looks like it might be a vacuum leak.  Yep, that will be letting a bit of air in.  Found another one of these in a similar state over on the offside inner wing. I don't have a diagram of the vacuum system yet so not actually sure what this does just now...There are a lot of vacuum lines on this car as a lot of things operate off vacuum. Central locking and headlight height adjusters to name two.  I'll probably go around and change all of these boot connectors at some point as they're all a bit soft. Thankfully the lines themselves are plastic and still seem in fine shape. Speaking of rubber that needs changing, the supply line for the self leveling suspension is looking rather sorry for itself.  Will look to get that changed soon. I do need to confirm what type of fluid this uses - though the initial glance at Google seems to suggest that it's basically LHM with a Merc logo on. Which would be nice as I've a load of that in stock. It certainly *smells* like LHM. I think one of the first non mechanical tasks will be seeing what I can do to straighten this roof lining trim.  This panel needs to come out anyway for two reasons. One is to replace the tailgate gas struts, the other is to fit rear speakers as there currently aren't any. The moulding is basically fibreboard and I imagine has got wet at some point. Hoping that with a bit of persuasion I might be able to get it to sit flat again. Apparently getting this hooked back in place is a pig of a job so hopefully I'll only need to do it once. |

What do you need to do to pull the rocker cover on a W123 with this engine? 1. Remove air cleaner housing (4 10mm nuts and pop two PCV hoses off). 2. Remove HT leads from the little plastic channel they sit in. 3. Detach the throttle cable at the engine end (little ball and socket setup, just pops off) and feed it back through the cable bracket.  4. Remove the nuts (noting that one is a bolt and post arrangement to hold the ATF dipstick in place). 5. Lift off rocker cover. That's it...ten minutes tops. It's almost as though someone during the design stage thought that you might need to service a car one day. Speaking of servicing, that's something somebody earlier in this cars life didn't pay much attention to. She clearly never had regular oil changes... it's quite manky in here.  Sadly there is evidence of damage due to this...the camshaft in particular looks to have taken quite a beating, a couple of the lobes on cylinders 2 and 3 have some really rather nasty scoring.  That is why you should change your oil and filter regularly, folks... Valve clearances were a mixture of slightly loose, perfect and slightly tight. I think whoever was last in here just set them all roughly to 0.2mm from the feel of it. With them reset she does sound better, though a couple of valves definitely are still clattery. I suspect trying to quiet things down far is a bit of a lost cause given the state of that camshaft. One thing I am definitely going to do when I've next got an hour free will be to pull the spray bar off and make sure that all the holes are clear, if it's clogged the cam will obviously be starved of oil. Solving the issue properly isn't necessarily a huge headache given that I just happen to have a complete spare head sitting in my conservatory.  In which the camshaft looks like this.  So somewhere down the line one of two things will likely happen. A: I swap the camshaft and rockers over from the spare head. B: I drop the spare head off to be professionally cleaned, inspected, valves lapped, new valve stem oil seals fitted etc...and then just swap the whole head over. B probably makes the most sense - though in the same breath the bottom end of the engine has suffered exactly the same degree of neglect...so dropping a lovely rebuilt head onto it without doing any other work might be a bit silly... though I do keep being told how hardy these engines are...so we'll keep an eye on things basically. Regular oil changes will definitely be adhered to though going forward! I'm not immediately worried, but definitely want to keep an eye on things. |

Given we had obvious signs of poor lubrication on the camshaft that at least verifying that we had clear holes in the spray bar made sense. Especially as I had a spare present on the spare head, so simple to clean that up and just do a swap. Here's it having just been removed - it has four pretty small holes in it which provide a drip feed of lubricant to the cam lobes, one for each pair.  They are pretty tiny.  Despite the head that came off being about 93% cleaner than the one on the car, only two of the holes were clear...doesn't bode well for the one on the car. I gave the "clean" one a thorough clean and got it flowing nicely. Ten minutes later, had them swapped over.  Having clean metal to contrast it against really highlights how grubby that top end is. All back together.  Has it made any audible difference? Not really. Though at least I know there's a good chance of lubrication getting to where it should now. The old one was pretty manky indeed.  Only one of the holes was clear, one other was about 50% clogged and two were completely missing in action - and you couldn't even see them for the gunk...so I think this was worth doing, even if most of the damage is already done it makes me feel better. Being finished messing around under the rocker cover for a while I decided it was time for us to actually change the oil and filter. Went out for a run first to get everything nice and warm and to ensure as much of the gunk was stirred up in solution as possible. Sump plug unsurprisingly is really easy to get to and came off without excessive effort. What came out was really dark but I've definitely seen worse. It was dark brown rather than black ink like you tend to find in diesels. Oil filter has some crud immediately visible on top of the filter even before it was pulled out.  This definitely looks to have done its time...the fact that part of the filter has collapsed tends to suggest to me it's a bit plugged.  It has actually pulled the element away from the top cap there. Out of curiosity I will dissect this filter to see if there's any evidence of issues visible. New filter in, new O-ring and copper washer fitted to the filter housing...  The old O-ring had (like the rocker cover gasket) pretty much turned to plastic. Double checked I'd refitted the sump plug... possible to do easily from next to the car as you have line of sight of it from above.  Then refilled with some fresh oil, started up and checked for leaks. None present. I'm not used to seeing this sort of thing actually making any visible difference...but this has where hot idle oil pressure is concerned. When at full temperature, in gear at idle I used to see 1 bar or fractionally above of oil pressure (it jumps off scale as soon as any revs are really used).  So it looks like I've gained somewhere in the region of 15psi of oil pressure at a hot idle. Not going to complain at that. I may try 15W 40 for the next change (10W 40 or 15W 40 are recommended) and see if that makes a difference. Think my oil change program on this car is basically going to be "Change it as soon as it starts to look dirty" for a while. |

Worth running some super thin/flushing oil through it? I don't want to get too aggressive and have never really trusted the use of flushing oils in a really grubby engine. Main reason being the potential for large chunks of crud to break off of wherever they have been sitting for years and ending up blocking critical oil paths. I'll be using a more gentle approach and just using oil specced for diesels instead. This has a higher detergent content to deal with the carbon which inevitably builds up in them more. |

If the car is cat less, find an oil with ZDDP in it. This will help preserve what is left of the cam until you decide where to go with the engine.
Fair play though, you are doing everything that can be done. Trouble is these cars suffer from the attitude of its "bombproof, so I don't need to be worried about the servicing". Annoys me. Previous owners not as thorough as you, or as caring and practical.

Previous owners not as thorough as you, or as caring and practical. Good point, I keep forgetting that they don't put the zinc additives in most (any?) oils these days. Not sure if it's something I'll find on the shelf anywhere locally but additives you add to the engine yourself are readily available online it looks like. |

That poor engine looks so neglected. I wonder when the last oil change was carried out before you got to it!? Not that long ago, this neglect is historic. Sadly back in the day some people seemed to take these cars reputation for durability as meaning they didn't need any maintenance! -- -- -- After 30 or so miles today the rocker cover still looks to be oil tight...except for the oil cap which looks to be weeping.  I did check that the PCV was clear when I had the cover off and it seems to be. The problem I think is actually that the paint is flaking off the rocker cover meaning that the sealing surface isn't flat.  My solution is pretty simple...scrape the remaining paint around the cap sealing surface (having stuffed a rag in there to catch the flakes). Yes I did spot I'd missed a bit after taking this photo.  We'll find out next time I have the car out probably tomorrow. Only other thing I did today was to get the new front speakers fitted. These had been upgraded at some point in the past, I'd say somewhere around 2000 based on the speakers found. Discovered why they rattled so badly... because they weren't screwed in. Just sitting on top of the dash. Turns out this has also has resolved one of the main rattles in the dash in general. The new ones are just cheap units (all of £16 from Halfords) but that really does show how far speaker technology has come over the years in that they're far better than the Sony ones that came out.  The dash moulding here is actually metal under the surface so now these are screwed down they are very securely anchored. The grill just fits over the tweeter thankfully. Equally thankfully the neon orange is completely hidden behind the grill. The passenger side one sadly has one broken clip on it so the grill doesn't clip down securely at the front edge, I'll need to see what I can do about that - as I'm certainly not paying the £50 someone is asking for one of the covers on eBay at the moment. I need to take some measurements to confirm if I have enough depth to play with, but if so I'll probably just throw a set of the same speakers in the rear. As you've only got little 4" enclosures to play with (though the front ones do have proper acoustic foam in the enclosure behind them) I don't really think there's a huge point in paying big bucks for speakers. What I'll probably do is look into getting one of those little self contained under-seat combined sub and amplifier boxes to just help things sound a bit more rounded out. Should be easy to just run the wiring through the centre console as well without needing to dismantle too much. Speaking of wiring...I really do hope that Mercedes included wiring for the rear speakers as part of the loom as routing wiring all the way back there will be a major faff. Especially with the speakers being mounted in the head lining. Not holding my breath there though! I know audio is really low priority compared to a lot of things, but it's one of those things which make the car nicer to live with so I'd like to get it properly sorted sooner than later. In more useful news, a set of bootlid struts have now been ordered. The next specific task I'm probably going to go after will be the trim on the bootlid. It's tried to cut my wrist twice walking round the car now and I really don't want that happening to some random member of the public who then decides to sue me. Trim is one of the things which just aren't available new for these cars and the prices for used parts are just silly if you look at the likes of eBay, so it's a case of make do, mend or wait patiently until something turns up at a sane price, most likely found through word of mouth rather than any internet search. Tyres will probably be getting changed next week or the week after. She will be getting a full set of Uniroyals fitted, and (if it's better than the current one) the best will be retained for the spare. She does wander around a bit so I'll have the wheel alignment checked while we're there - I think the main issue though is just a bit of play in the steering box which we might be able to improve a bit with some adjustment. So we are doing more important things than just replacing speakers! |

On the oil bar (that you replaced) - those pin holes look v v small - couldn't you open them up a smidgen (literally a minute amount) to help things slightly? Just a thought.

I'm tending towards assuming that the designers of the engine knew what they were doing. I reckon so long as the engine isn't neglected it should be absolutely fine. Especially using decent quality modern oils. Let's face it, if it was a major weakness in normal use these engines wouldn't have the reputation they have for dependability would they? |

It was interesting to see engine vacuum being used in the 80's for so many systems in a luxury car. There is a YouTube channel "Auto Anatomy", who restored a barn find 1966 Ford Thunderbird. Just like you, he found that the rubber hoses had perished and failed. If I recall, he just bought a new roll of hose, replacing all the old hose with new, one piece at a time, because he did not have a hose layout diagram. That's a lot of work though.
I love a nice estate/wagon - you have a keeper there.

Engine vacuum is one thing, but this car has an engine independent vacuum system. One pump and a few accumulators, plus metres of plastic pipe running to door locks, headlamps, fuel flap.
All "powered" from a central pump. It's great when it works, a curse word when it doesn't, but unlike electricity you can hear it leaking, or see it using a Wilko plant sprayer and washing up liquid solution. Oh, and it doesn't need a multimeter and won't blow fuses.
