Cylinder 2 and 3 put air to it for a leakdown test does not pass valve bent or stuck not sure called the place we got motor from and there sending new with air in the cylinder you can actually feel it coming out of the exhaust its crazy has 145 compression at idle or just by cranking and no start still 145 leave compression tester on it bring the rpms up and compression starts to drop thank you guys for all the help

Wow - that's very odd that it was doing that. Lifter maybe pumping up and not allowing the valve to close under rpms... or weak valve springs?
