2.3L Engine Swap - The Bad and Ugly

Some parts of my engine swap have not looked so good. The flywheel was a nice shade of pink and had a few cracks. I'm glad I have the GS aluminum one. I had the Viggen clutch and pressure plate installed 2 years ago, it still looks good.



The ugly showed up when I removed the cylinder head. I knew the engine was burning oil but I just replace the head gasket and cleaned the pistons 6 months ago. It looks like some sort of coral reef is growing on the valves and pistons. It's not just a discoloration, it is 2-3 mm thick, cylinder 1 on the right is the worst. I’m not terribly worried about the bottom end because I have the 2.3l, but the condition of the valves disturbs me since I just rebuilt the head 6 months ago. I am hoping the head will be okay with just a cleaning. Only cylinder 3 looks good. Cylinder 1 looks terrible, lots of oil in it. I can't believe how well the engine ran, except for the smoke cloud I would not have known.

Eric, can you pull the 2.0 apart and just pm or put up a post on the casting numbers (basically like the 2.3 thread) I have a spare block that looks like a 2.0.
