Had some more time yesterday/today to continue diagnosing, long story short decided head gasket's gone or head's cracked. Blowing bubbles in the coolant. Not going to fix it, was gutless anyway with the 33's. Working on getting drivetrain swap parts together, going to look at a donor vehicle sometime this week/weekend. Look for an engine swap thread coming soon to a forum near you.
