DONOR LHEAD LEAK DOWN TEST RESULTS

[boucher]

HELLO:

I PERFORMED A QUICK LEAK DOWN TEST ON ALL CYLINDERS LAST NIGHT AND THE RESULTS WERE ALL THE SAME.

HISSING COULD BE HEARD FROM ALL EXHAUST VALVES. COULD THIS BE AS SIMPLE AS CARBON BUILDUP ON THE VALVES OR SEATS?

THANKS

PETER

Usually one of four causes, 1-guides leaded/carboned up and valves sticking slightly open, 2-lead/carbon deposits on valves faces and seats, 3-soft tired springs, clearance set to tight.
