I'm looking for an answer, not a blank page. What is the problem with my question, because I don't know?



Why do you want to know ? Do you want to rant about something? In the big picture does it really matter ?

It is what it is, nothing is going to change the way the parts were made decades ago.

Personally I can't think of any other engine that had wet exhaust bolt holes, but I have not worked on every engine ever built.
