Documenting my first engine rebuild

Entries in this blog

Popped the head off today

I popped the head off today. Lots of rusty gunk clogging the water passages, but everything looks pretty good. I see some light scoring in the cylinder walls of #1 and #4, but I can only just feel one line. Pistons are still factory 88.97, so lots of cylinder wall left for an overbore. Next, I need to give the cylinder head a good cleaning and inspect for cracks. Maybe tomorrow. I need a parts washer.

Peek inside the oil pan

Tonight I decided to take a quick look inside the oil pan and see what I could of the cylinder walls from the bottom end. Doesn't look too bad. I couldn't get any good photos of the cylinder walls, but no signs of scoring from this end. We'll see in a few days if it looks equally good from the top end when I get the head pulled. Minimal play in the oil pump chain. More sludge in the water pump. Impeller was in good shape and bearings felt good must be a newer water pump. The r

Hitting the Pause Button

I'm setting this project aside for a while. I just had my floors replaced and a 5 speed installed, leaving the project fund depleted for now. The car is running and driving great, so aside from a few small projects, I'm planning to just enjoy the car when the weather allows. Late spring or early summer, the 38/38 will be replaced by a 318i manifold and Ford edis-based megasquirt efi conversion. After that, I'm considering going turbo, which will completely change my build plan for the block.

First Look

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

Bottom end disassembly complete

I finished tearing down the bottom end and getting all the manifold studs removed from the head. Lots of signs of wear as I would expect from a 43 year old engine that doesn't appear to have ever been rebuilt. This post is basically just a photo dump to have a future reference. I got a new toy and will probably post an update in the next few days after I put it to use; http://amzn.com/B000XQ2T1E Need to reshoot the crankshaft. I thought I took a photo of each, but apparently n
