Anyone know who makes a tool to do a leak down test on an engine with the cylinder head off? AST made the following tool but they say it has been discontinued for a few years:
The reason I need it is I took the head off a 4 cyl. car suspecting a blown head gasket and after putting it back together it still has over 80% leakage in the 2 center cylinders. After pulling the head again and taking it to a machine shop, they said the valves vacuum tested fine and the surface flatness is in spec. and for me to check rings. My third world test is to bring the pistons up to the same level in each cylinder and pour in an equal amount of transmission fluid and wait 24 hours to see how much the level drops. I'd like to do something more scientific if someone makes such a tool as AST did.
