Im getting ready to disassemble my valve springs and im using an adapter to keep the valves up with compressed air. When I put the adapter in and hook up the air hose a lot of the air is getting past the piston rings. Its equal in every cylinder sound wise I don't have a pressure gauge. This is a 496 big block chevy that has never been fired. Im thinking/hoping it's because the rings aren't seated yet??? Its not leaking past the intake or exhaust valve just the pistons. What do you guys think? I cant find anything online that's helpful with a new engine. When I compress the valve springs there is still enough air present to keep the valves up even with the triple spring setup I have. Any ideas?
