Don't worry. They'll come. Hang in there.

I had my shims done at a BMW Mech here in JHB. Reason was, shims take about 2 weeks to arrive from Germany. So you need to measure all your clearances, work out what shims you need, order them, wait, install and remeasure, praying that you measured correctly the first time...I took it to someone who had shims in his workshop, so it was a quick job
This is helpful. Thanks. Which Bmw mech in JHB was it if I may ask? I would pm you, but not sure how to do it in this forum.

Buy it and put the motor in a 3 series box šHaving said all that, the E34 M5 is not that fast, especially at altitude

Peter AEW, he is on this forum
haha, nah e30 doesn't look as sleek as the e34.
The mechanic in question. Most of the troubleshooting tips he gave in this post were problems you found while fixing the car.
Yep, that's why I turn to this forum for advice. Plenty of clever chaps over here.
Hey guys, its me again. It looks like the water pump on the s38 (different water pump to the m30) is in its death throws and BMW don't stock them anymore. They seem to be difficult to come by. It seems we may have to rebuild the original which I know is obviously not ideal but there seems to no alternative. Does anyone recommend a guru in SA that is capable of rebuilding such a water pump?

Unlucky...I have exactly the same situation with mine...someone used locktite to keep the viscous fan on the pump - so the water pump got damaged while trying to remove it š¤¬
Unfortunately, none of the OE suppliers seem to be stocking this anymore either, seems even the cheapie $30 dollar pumps are NLA. I have heard of guys transplanting the internals of a M30 pump into the M5 housing, you need a bench press and be very careful indeed... would also assume that the brand/manufacturer of the 2 pumps would need to be the same.
Surely someone needs to make another batch of pumps at some point...please keep us posted

Alright guys, some developments with the old beast:
1.) Managed to refresh the entire rear sls suspension with new accumulators and had the shocks themselves re-conditioned with new seals. Previously the ride was very harsh and uncomfortable, now it rides really nicely. So far I'm glad we stuck to the oem standards and keeping the suspension as original as possible.
2.) After some major anxiety we were able to find and order a new water pump for the car as the old one was in terrible shape (so much vibration that the fan fouled with the shroud and broke) So, new pump, new fan and new shroud. We're sending the old pump to be re-conditioned, hopefully it's not too far gone.
3.) I'm quite keen on doing the valve clearances on the s38 but you need a fancy tool to depress the buckets to extract and replace the shims. This tool you can no longer get from BMW themselves. Luckily, there are aftermarket companies that manufacture the tool, so we managed to order one from Schmiedmann in Denmark. So valve clearances are next on the to-do list along with changing out one of the rear speakers and a good detail. "Nearly there!" I say cautiously but optimistically. Enjoy the weekend.

Hz it.. I would say, clean your injectors. I fitted the 260cc injectors on my 535 and what a transformation, but the consumption and black unburnt fuel wen cold was a issue..
Hi there, we had the injectors redone properly, also replaced the o rings
