Tech / General EngineIs your car making a strange sound or won't start? Thinking of adding power with a new combination? Need other technical information or engine specific advice? Don't see another board for your problem? Post it here!
I am having this same sound and wondering what that is. It only comes on after the engine is just turned off and is about 5 sec. on the passengers side of the engine. I did have the heads milled down to 63 cc from 65 and not the intake. Could it be pressure being released after the engine is turned off and a bad seal from the intake not seated and leaking from the intake gasket?
