Diagnostic Techniques
If one or more cylinders are identified as
having 10 to 15 PSI greater compression
loss than the others, you can listen for
escaping air pressure to diagnose the
problem. Air escaping at the following
locations indicates a potential problem.
1. Oil dipstick tube indicates pressure
escaping from the cylinder into the oil
jacket. This usually indicates stuck,
burned or worn rings or cylinder walls.
2. Carburetor or fuel injector
intake indicates stuck, burned
or worn intake valve.
3. Radiator filler opening bubbles or
sound indicates pressure escaping into
the coolant jacket. This can indicate
cracked cylinder walls or a damaged
head gasket. In case of a damaged
head gasket, often two or more adjacent
cylinders will show the same problem.
4. Adjacent cylinder indicates a
damaged head gasket.
5. Tail pipe indicates stuck, burned
or worn exhaust valve.
