Have a 502 MPI with 85 hours on full rebuild, yesterday on about a hour run it started to get some milky oil. Cylinder 2,4,8 have 140psi of compression cylinder 6 has 130, there appears to maybe be some rusty water stains below the head on that side but wishful thinking wants to believe it was from washing everything after rebuild. Would it be safe to say it needs a head gasket? motors are in a 32 fountain and about impossible to check the other bank. Boat stays in 60* building all winter so know its not a crack from cold. Ran great the last 3 weeks out as well as yesterday. attached are the plugs 2,4,6,8 as well as the oil which starts off green as Kendall use to be
