I don’t honestly recall. Whatever was called out in the Cummins book. did it way back in December. I just remember thinking that maybe the gasket blew out on the outside of the jacket.
I’m gonna give this deck plate a go. Gonna pressure the water jacket to 15 psi and then try to pull vacuum thru the cylinder and see what happens. That’ll be the final test and then I’ll just start putting it back together, see what happens from there.
