Finished dismantling my second 3.2

I bought an engine in pieces last year. I got the engine into my car this past summer and now have over 1500 miles on from track use as well as breakin.

I felt confident enough to take my original 3.2 and start to break it down for rebuilding, so this is the first engine I have seen broken down and not cleaned and machined.

I was surprised at how little wear was visibly apparent.


This is the bearing for the timing chain sprocket. Is this wear because the timing chain is pulled against this side of the bearing where the timing chain wraps around the crank?





This wear is the last bearing on the crank at the flywheel. It's the only crank bearing to show any wear at all. I am leaving the bearings in place for the machinist to see if these mean anything.

Is this normal because the greatest force is here because there is no other bearing beyond this point?




These are the crank bearings and you can see they are nice





I know there is a lot of debate on whether we should use o-rings and oil or o-rings and silicone. I used o-rings and oil on my rebuild.

I have to say this looks a lot like the factory uses a sealant other than oil and o-rings.

Thoughts?
