Engine + Driveline / Clutch/TO bearing Replacement

Thanks! One question - when you removed the trans did the engine need a separate support? I see a jackstand under it in one photo.

I don't have a decent manual for my '91 318IS(M42) and the throw-out bearing is going south fast. New parts will arrive Monday (clutch kit, pilot bearing, bolts, etc.) but I'd like a DIY tutorial to guide me through the process. Anyone have a good link, or a PDF from the Manual?

M42 Reference / Cylinder head flatness
« on: August 14, 2006, 08:30:35 PM »
I took the head to a local shop for the resurface and pressure test. They removed the cams to let the valves down. He called later today to say he would have to remove the valves also. Seems there is only .003 inch clearance between the present head surface and the edges of the valves. I'll have him measure the overall height to see if it's still standard (140.00mm).
Does this sound normal to you? Pretty close!

That's what I was looking for! Thanks, and where do I find the rest of this manual?

I live in Salinas, CA, and it's hard to find a good shop. The last one I used when out of business. I may have to look towards San Jose.

It's funny how the manual says to check for warp, but doesn't say what the limit is for this engine. The most stringent requirement I've found is .03 mm, or .0018 inch. The least stringent is .10 mm, or about .0070 inch.
The car was running fine. Just replaced radiator for broken tank and housing cracks. But, on cold startup, engine would misfire for 20 seconds or so. I pulled the plugs and checked compression - OK. I pulled them again after overnight cooldown; ejected water from #2 cyl. Not much, but enough to know something wrong. After pulling head, the gasket is shiny on low side of #2 cyl.
Stoned entire surface with fine machinists stone; high spots adjacent headbolt holes, and lows between cylinders and on exhaust side of cylinders, between bolts. I think a new headgasket will compensate for warp, but I'd like to be sure. I'll check into cost of resurface and/or rebuilt head. I'd like to avoid messing with cams and lifters, though.

It leaked thru the warp area just slightly. No visible cracks. I stoned the whole surface to highlight the highs and lows. The deepest warp is adjacent to #2 cylinder ( the one that collected coolant overnight) and is about .0025" deep.

I've searched and searched through this site and others but can't find the acceptable limits of warp for my M42 head. Mine is a little wavy, about .0025" (inch) out of flat near #2 cylinder, where the leak in the gasket occurred (overheat incident). Should I resurface?
