Leak down test can help you determine what is going on without tearing down the motor. My personal knowledge of diesels is limited to those with glow plugs as you can access the combustion chamber through the plug hole in the same manner as a conventional engine.
This leak test shows how much is lost, where it goes, and provides a great indicator of engine health.
