Karl and fellow vanagon types
I spoke with Larry on Saturday and went over the problem and he did mention
the loose head nut. Tightening the heads is a multi sequence operation first
snug the 25 pds then 37 pds you cant miss one nut that many times.
I don't see that you can say AVP messed up that many times no way Leonard
does this every day. I do think you could say that the nut did not stay
tight and why ? For me the rebuild OEM heads would be my first concern
Karl did the engine you are talking about have rebuilt OEM heads.
I cam to the conclusion that the coolant system had not been bleed corretly
by the shop that did the radiator repalcement and Larry felt he may have
exhuast gasses in the coolant but the test they did showed negitive rezults
Time will tell
party on
going faster miles an hour with the radio and the heat on
Its almost spring right
