That is rough dealing with fishing it out. Even with those screens I still used a lot of paper towels. Added to the paranoia is that I already did my oil pan gasket and rod bearings and would not want to do it again .

Yeah I plan on placing a lot of shop towels in every potential area where a shim can fall into the engine when I do my valve adjustment in the next few days. I don't want to go fishing for shims. How hard was the DIY on the Rod bearings?

It is not bad, but it is A LOT of things to keep track of since you have to take off the power steering pump and front subframe. Then your shopping list gets long while you are in there (you of course don't have to)... you can replace all power steering hoses, want to upgrade to different steering rack? upgrade/replace tie rods? other suspension and brake components? Etc. I would suggest getting an engine support bar or renting one.

Here is a great diy: http://www.m3forum.net/m3forum/showthread.php?t=455681

It's not that bad, honestly, especially for a pre 2002. Tedious, yes. I stripped a few of the bolts on 2nd or 3rd step just because of weird positioning on my part (getting enough rotational clearance, did it on jackstands so that also does not make it easy, torque wrench I had was like 3 feet long, etc). Absolutely doable, don't sweat it.

Since we were chatting vanos cam bolts and locktite, there is another little gem under the oil pan that requires a bit of locktite attention, the oil pump nut (reverse threaded).

If you have the time/means, do it! Prob time to replace some of those parts anyway (if anything else, preventatively), and you'll learn a tonne.

Agreed! I learned a lot when I did the rod bearings on my car!

sorry if I am asking a stupid question, this is next on my list once I figure out the clunk problem I am having (This THREAD).

Anyway I have converted to electric fan, just wondering how to go about turning the crank around and what socket/tool I need? THANKS!

First page of this diy (a very detailed diy) lists everything you need, like "32mm hex socket or BMW crankshaft torx socket (PN: 83300491056) or 36mm 12-point socket - see step 44 for details" and how to figure out which one you need (depending on production date).

Question - I have observed others, and was taught myself, to turn the motor by using a wrench on the camshafts rather than the front fan nut. See here, between cylinders 1 and 2, where the camshafts are not round:





I have not seen online anyone else do this... I am wondering if I was taught incorrectly or if this is an acceptable method, as it saves from having to remove any of the fan components.
