I would use some wd40. Plus it’s also a rust inhibitor.

Cant this be counter productive and keep oil away the way that baffle is set up ?

I did check the crank for scoring and saw nothing. I’ve seen several engines and this 4g is the first I see with such a thin casting for the thrust washer. To me it seemed some what incomplete.

The lip where the thrust washer sits. The other side has more meat to sit on. Thank you for your reply.edit. Towards the bottom center is my concern.

This part of the block has got me iffy as it seems very thin. I saw some pics of another block but can’t tell if it’s normal. Surface is where the thrust bearing sits.

Thanks for the replies. Yes I was planning on going .020 over but now will be waiting to see what my machinist says. I bought the engine used just to get it running and dropped it in. I know the previous owner was beating on this engine and had it sitting. Perhaps he knew of the issue. Engine...

In the process of rebuilding my engine I stripped everything down. Inspecting the block cylinder 2-3 have wall damage. It feels like ribbed grooves. Did 2-3 run too hot? 1&4 are good.
