Title: Carnage Pics
Post by: derek9702 on November 22, 2008, 02:58:04 PM: Monday morning I started my 94 318i to go to work. After about 10 seconds, at idle, I heard a loud rattle, and then the car shut off.....not good. I then tried to start it and it was locked up tight....again not good. It sounded like a rattle from the timing chain, and I was hoping that one of the timing chain guides let go. I opened up the oil cap and saw plastic, so I figured upper guide???. Just to be safe, this weekend I started pulling spark plugs. I came to the last plug and noticed the electrode broken off. So I decided to take the head off, the accompanying pics are what I found.

I know one piston is a loss, so I was thinking about honing the cylinders and installing new pistons, and replacing the head. If anyone has a good rebuilt head laying around, let me know:)

Maybe you should just upgrade and swap in an M42+getrag 240. They come up for sale very regularly - I think there are some now in the for sale section.

I don't think they had M10 engines in '94. :D

Good luck with the rebuild.

Good luck.

Post by: Jimmy Lewis on November 24, 2008, 01:27:53 PM: You could have a shop reman your current head for much cheaper than $725. But how do you know that your current head is shot? This isn't an over-heating issue, I doubt the head sustained any real damage, besides the valves, retainers, and obviously the timing components. If you aren't up to the rebuild just find a low miles M42 out of another e30 or e36 and swap it in, there are tons of people swapping out perfectly fine M42s for 24v motors all the time. Find a decently low miles one, replace the timing components, check for problem areas such as the upper pan bolts, and throw that bish in there.

Post by: derek9702 on November 24, 2008, 01:39:27 PM: The head surface is ok, never had an overheating issue. I know for a fact that 4 valves will be replaced, and I'm going to replace the lifters as well (146k Miles). I'm working on disassembling the lower end now. Any tips on crank bolt removal?
