Cold engine. No
oil placed in cylinders. This is with a new leak gauge.
Summit Link
Cylinder 1 - 3% leak
Cylinder 2 - 3.5% leak - minimal hiss in exhaust
Cylinder 3 - 2% leak
Cylinder 4 - 4% leak - minimal hiss in valve cover
Cylinder 5 - 3% leak
Cylinder 6 - 3.5% leak - minimal hiss in exhaust and valve cover
Cylinder 7 - 4% leak - minimal hiss in valve cover
Cylinder 8 - 2% leak - minimal hiss in valve cover
I would think that with these numbers, there is not significant blow by. Especially when the engine warms up, the rings should get tighter and less blow by in the valve covers. I'm not sure about the exhaust hiss. I have hydraulic lifters. They may be too tight - they are set at 1/2 turn past zero lash.
No smoke in the exhaust. No water in the
oil.
Going to add a 5/8 inch line from the PCV to the throttle body. Going to add a 5/8 inch line from the breather to the intake filter. See what I come up with. No current photos of the motor, but will add photos soon - likely tomorrow, though.
