Here are the findings from a leak-down test: I had the compresser set to 80 psi and I set the regulator on the leak-down gauge to 70 psi
Cyl #1 down 2psi
Cyl#8 down 4psi
Cyl#4 down 9psi
Cyl#3 down 5psi
Cyl#6 down 22psi (air is coming out of the exhast port on the lower unit)
Cyl#5 Down 2psi
Cyl#7 down 4psi
Cyl#2 down 2psi
All of the air that is leaking from #6 is coming out of the exhaust outlet on the lower unit. I am gatherng that I have a problem with an exhaust valve and/or since it is a fresh water cooled engine, possibly the head gasket. I am still burning large amounts of oil, and the plug from number 3 and number 5 have a white calcium crust on them. The remaining six look pretty good, chocolate/dark brown.
