The first and rear main bearings look excellent!

Someone mentioned zddp being taken out of the newer oils, so true, watch out for that. Supposedly they are taking the zddp out to save catylitic converters and energy conservation efforts.

Just for some quick info on that, I recently messaged castrol's "expert" chat, and they said that the Castrol Edge 5W-50 (formulated for classic cars) has 1800ppm of zddp! I did not ask about the phosphorous levels though. For some reason I never thought about the zddp levels protecting the mains.

I am assuming that you pulled the main bearings off since your going to put some fresh ones in, that is an excellent idea.
