Looks like -40mm and bigger rims is my best choice then  sounds like a curse word to get it slammed and I can see it being a disaster waiting to happen. Also on a completely different subject, my engine has started tapping constantly... I know this isn't good news but is it completely buggered? |

Looks like -40mm and bigger rims is my best choice then sounds like a jolly pain in the backside to get it slammed and I can see it being a disaster waiting to happen. Plus according the Haynes bible of Sierra, you need to remove the drive shafts to fit the rear spring. What a bloody load of hassle  Also on a completely different subject, my engine has started tapping constantly... I know this isn't good news but is it completely buggered? What engine has yours got? |

Sierra - here we go again! He has an illness, it's not his fault.

I'm sure you could plant one firmly in the weeds but as mentioned there may be issues with pretty major rear negative camber and the front is likely to catch like buggary. If you have the time and skilzors I say go for it. But you want a relatively hassle free life get the -40's and some decent adjustable dampers.

Which rear end does your Sierra have (discs or drums??)
I found when swapping rear springs on the 4be that is was a fairly quick job. On mine, drive shafts were connected to the diff with 6 Torx bolts (t40 I think). The safest way to undo these I found was with an impact wrench. I used on of those cheapy 12v jobs you can buy for wheel nuts. Never rounded any of the bolts, which is quite likely if you lean on a breaker bar to undo them.
I also found that I couldn't do it without disconnecting the brake hoses as I couldn't drop the rear arms far enough otherwise.
Never worked on a drum braked rear though, so don't know if it's exactly the same or not.

Drum brake rear ends have driveshafts which just slide in rather than the bolt-on ones, I don't think I had to remove the driveshafts when I put the -40mm springs on mine.
Not entirely sure about the tapping noise as all the CVH Sierras I've driven already tapped! Hydraulic tappet seems the most likely cause though although that's where my CVH knowledge ends I'm afraid!

Having lesft that Q to the others all i can add is that i have *heard* that the tappets are hydraulic, often take a couple minutes to sort emselves out, and that hight mile engines get more chattery.
Apart from that i dunno, a service may make you feel better if it has not has on in a while, works wonders whether it fixes oey or not!!

 it doesn't matter if it's a Morris Marina or a Toyota Celica - it's what you do with it that counts  |

CVH tappets are indeed hydraulic and are famously noisy with old age (unless you have a RS1600i which have solid units), a new set is pretty cheap if i remember rightly.
as Re-an says, they take a while to sort them selves out as the oil drains out of them when they are standing. if it still happens once its well and truely up to temp and a italian tune up hasnt helped you could replace them. if its not bad then you could live with it, fresh oil and filter may help, but as i said before, they are pretty cheap and are ceartainly easy to replace. (pop the rocker cover off, then each rocker un bolts, the lifters pull out. reassembly is the reverse (you might have to torque the rocker nuts up, cant remember)
cams wear badly (considerably quicker than most engines aparently) but i have no experiance of what this would sound like, would it cause a ticking noise? new standard cams are pretty cheap on ebay.
early engines also had shonky valve stem oil seals, and later 'modified' ones are far better and again are cheap and easy with the funny tool for valve removal.
lastly, the tend to get clogged up around number 4 cylinder making them pretty asthmatic but i don't know if it is very easy to sort without popping the head off.
hope that helps. they are not bad engines, a few faults with them but they are easily fixed at pretty low costs.
