Nothing major happened, apart from a necessary transmission fluid change. And - nothing to report here either. But I though it was worth mentioning that the oil smelled, looked and feeled like new. Not a single piece of dirt, no a hint of abrasion. Usually on old transmissions, I find a hint of dust-fine particles in the oil. Not the case here. So I guess the transmission is in good to very good condition.  Have a bunch of nice holidays! Cheers, Jan That look almost drinkable  |

Wee update; I had a bit of a dry spot at work, so I - again - tried to seal the leaking front screen. Looks like this time it was successful. And whilst the car was inside, I patched up the biggest holes in the rear silencer...  Would need a couple more, but I ran out of fcuks to give pretty quick... Center silencer is looking pretty bad as well, I think I'm going to replace it with a bit of pipe, should it fall apart. So the Taxi can sound all race-car whilst going really slow... Cheers, Jan |

Hey! Still alive... Just very busy with work & life. Taxi is still doing fine. 1.032.000km currently. The aux heater is missbehaving, not had time to look into it yet. I suspect a bad glow plug, since ignition is troublesome. Once it runs, it runs fine. Today, after work, I replaced the water pump. Since the car was runing hotter than usual, even with the low temperatures we currently have. So - time to make it ready for the warm season in time. All went well. But... I've never seen this bad cavitation damage in an automotive water pump. I guess it's done a couple of revolutions...   Didn't change much, though. Maybe the gap between impeller & pump housing is just too large for good efficiency. Due to the cavitation - and what appears to be mechanical damage (maybe impeller failure in the past? Debris that went through the pump?). So I'm replacing the housing. Should have a good one somewhere... And that's all for now. But there's a lot to come soon, you'll see. I just thought this was worth showing since you don't see it every day. One of the things with ultra-high mileage cars. Cheers, Jan |

Is that an original part? Surely it’s still got a bit of warranty on it |

You need to ask yourself....... why am I seeing cavitation damage....... ok (very) high mileage, but Mercedes didn't design it to cavitate. Is there anything that could be restricting the suction side of the pump, leading to the cavitation?
Agree that the housing is done for and needs replacement - just thinking it might be trying to tell you something.......
Cheers
Nick

I've been told that that's actually a mild case of cavitation on Mercedes engines... The thermostate is on the suction side of the pump. Maybe that's a bit of a long-term problem? Anything else seems to flow well. Radiator is new-ish. But you are right, it might be clever to look for blockages and not do it away as mileage related I don't know how old the pump & housing are... Anything between 500-800.000km seems plausible. Cheers, Jan |

Thermostat on suction side......?!  Maybe they did design it to cavitate then........ Is there a small thermostat bypass route/drilling? Is it clear? Nick |

Mercedes did some weird sh!t in the 80's... I can't remember right now, but as said - I'll investigate. I'm going to replace that housing anyway. Almost forgot to mention; the belt tensioner needed replacing. Again. I think this ist the 4th time now... This time I went for an pre-assembled kit, tired of replacing the bearing. This is another "weird" bit; using a ball bearing for an oscillating belt tensioner. In the 90's they switched to a bronze bushing. But of course not without re-designing the whole front cover & tensioner geometry. And I replaced the rear sway bar links - and whilst doing so I discovered a stuck brake piston. New calipers on order - don't have the time rebuild the old ones. Cheers, Jan |

Hey, not dead - just seriously busy, my weekly mileage increased to well over 1100km. All is well, new rear calipers & pads and recently 4 brand spanking new tyres got installed. Car's got a wheel alignment today as well, as it never behaved as nice as it should. And the inside of the tyres was wearing excessively. Should be sorted now. Oil chnage is past due, maybe during the week. Current mileage: beyond 1.040.000. And a couple of weeks back, I even gave it a hand-wash.  That's all...  Cheers, Jan |

Hi! Time for a little experiment... R134a refrigerant ist getting ridiculously expensive now. So - why not use what's used in common household refrigerators? Cheap, environmentally friendly and readily available. So I bought the cheapest propane burner I could find. Attached it to the cheapest r134a filling hose I could find. With a couple of random fitting I found in the workshop.  I used a scale to weigh the gas bottle. It's about 290g propane/butane mix to replace 1000g r134. And after a while, the compressor engaged and refrigerant started to flow...  ...and a cool breeze started to come out the dashboard vents. Aaaaaaaaahhhh. Nice! Only one slight problem; the evaporator has finally given up the ghost. So it strated to smell of gas real bad. I had to evacuate it - so I'm still sweating. However - it works. And it does so rather well! And it's 5€ for a fill. Not sure if I continue with this, but it was a nice little experiment with a surprisingly well outcome. It has some disadvantages though, hence the following: Disclaimer: do not try this! It's a not an approved refrigerant, it burns and may explode. And it may harm your health and make you dizzy. You may loose insurance cover in case of an accident. Always use the approved refrigerant for your vehicle. That's all... 1.047.000km. Cheers, Jan |

I ran propane in my air con before i pushed it in to an X-Trail. It works really well! Enough to freeze the system and stop it working until it warms up again! Obviously, I was a bit worried when I folded it all in half. Luckily I had no leaks of any kind, the gas only leaked when we tried to pull the pipes straight again. But, pretty much everything else in the engine bay is flammable... |

Like it but, as a smoker, I'll stick with less volatile stuff!

Well I never knew that propane was used as a refrigerant! I've an unused 47kg bottle behind the shed; should keep the other half's Freelander cold for a while, not so sure about my Scooby! Or, perhaps not |
