Not the marks you like too see when doing a head gasket. Still feels smooth. Leaning towards broken ring?# 5 is the whole stoke. You can see #4 but haven’t rotated it

Saw your video about 5.9 oil squirters. I’m helping a buddy rebuild his 2006 5.9 and I’ve always noticed the blue or plastic plugs in the mains. This Eng uses bolt on style but also had these. Machine shop removed them and did there machining but never sent them back up. They did send a set but has small hole and not physically blanked. Do they need to be blanked or can they be used and not worry about loosing oil pressure?
