Strange sound

While manually turning the engine I can hear a pssssss like sound from what seems to be coming from the #4 head. Is this caused by valves being too loose?

You have 4 heads on your motor? Laughing

Not really it's just squeezing the air and then letting it out. That's what it sounds like to me. Do a compression check to be sure. Cool

Correction, The #4 cylinder/side of the head.

I always get that sound when turning the engine over by hand, i think its normal.

I was hoping it's normal but It only seems to be coming from the compression of one piston rather than all four. I will definately get a hold of a compression tester.

Put in only one spark plug at a time to see if really sounds different.

correct me if I am wrong, But your rings should not be rotating after they have set, right?
