Does the hydraulic lock happen in a middle of a run lets say or upon start up after turning the engine off and restart?

What's the best/easiest way to find out if you have a reversion issue?


everytime mine has happened, it was when I was slowing down from a high RPM run, I have 11k worth of new headers that should fix my problem.

Was it hydraulic lock or broken exhaust valve?

hydraulic lock leads to broken exhast valve wich leads to broken piston wich leads to broken block wich leads to broken heart wich leads to broken wallet wich leads to broken family....

The highest rate of reversion occurs at or close to idle. Reversion will cause corrosion of intake and exhaust valves. Depending on the cam grind you will get a great amount of cross talk between intake and exhaust at low engine speeds (idle).

The biggest problem with reversion is that water ends up in your oil. Most people mistake the water in the oil for a blown head gasket or leaking intake manifold gasket. Since water doesn't like being compressed when it enters the combustion chamber it squeezes past the piston rings and milks out the oil. If this goes unchecked your oil will break down rapidly.

Best way to check for reversion is to warm the engine up the run at or close to idle. Shut down and immediately remove an exhaust manifold/header and check for water. If it's wet you have reversion.

What is the "QUIT SYSTEM" of which you speak?
