Title: Please tell me they are best painted not polished !
Post by: McCabe-Thiele (Ted) on September 12, 2023, 02:30:13 PM: After yesterday's euphoria realised today that I had not polished the cam cover partly as there are some marks on the end cam bearing faces so was not sure if I needed to find a better one.

I have been advised that the upper bearings are not as critical as the lower ones in the cylinder head as the camchain & rockers push down.
The middle two journals look okay to me there is some radial scoring on one end in particular.

Bearing photos to follow.

Shame about number 4 journal surface, but it's usable.

I'd be tempted to dress that down a little, just on where the really rough areas are. Just in case it touches the cam.

I will definitely clean up the outside before I paint it - I was thinking painting is easiest tbh.

Not sure how you dress down a journal how do I do that please Ken?

I have some 1200 will that be a suitable grade of wet & dry?
