Low compression.

Check for exhaust valves that are sticking or burned.
Remove the cylinder head and recondition the exhaust valves. Refer to paragraph
3-89.
Step 2.
Check for compression rings that are worn or broken.
Remove the air box covers and inspect the compression rings through the ports in
the cylinder liners. Overhaul the cylinder assemblies if the rings are badly worn or
broken. Refer to para- graph 3-96.
Step 3.
Check for cylinder head gasket leaking.
To check for compression gasket leakage, remove the coolant filler cap and
operate the engine. A steady flow of gases from the coolant filler indicates either a
cylinder head gasket is damaged or the cylinder head is cracked. Remove the
cylinder head and replace the gaskets or cylinder head. Refer to paragraph 3-89.
