This is my first attempt at a blog, so why not use it to document my first attempt at rebuilding an engine?
I picked up an m10 from another FAQ member last night with the intent of doing as much of the rebuild myself as I'm able. I'll farm out machining and perhaps some of the head work, but I'll do the teardown and final assembly.
The engine in my 2002 is running fine so I'm going to take my time on this build. There may be long lapses between updates but that probably means I'm out enjoying my 2002.
When the engine is finished, I'll swap it out for the engine currently in my 02.
My goal is to build a street performance engine that can handle a bit of track time. Not quite sure exactly what specs I'll go with but I'm thinking 9.5 or 10.0:1, 292 or 304 cam, and mild porting of the head. More research to be done.
I'm currently running some bolt ons to an otherwise stock engine. This will be my baseline at the end of the project.
This is with a shorty header stainless downpipe, and stainless exhaust, all from Ireland Engineering. On the intake side, I'm running a 38/38 Weber on a hogged out stock manifold. Ignition is pretty basic with a blue coil and pertronix.
Tonight, I got the engine moved from a pallet
To a stand
Then I pulled the intake and exhaust manifold. Aside from a failed exhaust gasket on the #3 cylinder exhaust port, it all looks pretty good so far.
There's some sludge in the top of the head, but not too bad and nothing looks out of place here. Valve lash was good on 6 out of 8 rockers. The other two were just a tax loose.
Head is still at the factory 129mm thickness
This engine came with a 121 head. I also have an e12 head that I picked up a few months ago. I'll use whichever one my machinist thinks is in the best shape.
Any suggestions, feedback, comments, or questions are welcome.
