2004 3.2L 986
I took some time to consider all the good feed back in my previous post "Engine Rebuild" and realized I was possibly out of my league for this task.
Because of some of the comments and guidance that was given I spoke to a local race car driver and he recommended an engine rebuilder 2 hr drive away. After that two other people I know agreed with the choice of rebuilder. So I swollowed my pride and drove the stripped down engine there today.
The Findings;
We already knew the IMS bearing race was ugly, additionally one chain guide is broke (other piece close at hand), #4 cylinder had one broken ring and the forward most crank bearing turned!
All other bearings visually in great shape remainder of engine visually looks good.
Tomorrow parts are to be washed, assembelded to tourque and then measured.
If the main crank bearing needs to be turned are there oversize bearings (0.010 or 0.25mm) available? What other options are there?
What about the IMS bearing race, can the outer chain sprocket assembly with race be removed and replaced with new?
