Hi, How can the compression be tested without removing the plugs !

It can't. You can do a cylinder balance test with a scope to see how even they are, but plugs would need to come out to measure the compression in each cylinder.

Thanks, I may be looking at a pre inspection on a Mitsy V6 and the VTNZ lot said they have a "machine' that will do that . yea .

If it hauls ass and doesn't blow smoke the compressions probably fine. mitzy v6 can suffer noisy lifters thou

HOW TO CHECK COMPRESSION
Compression can be checked two ways: manually with a compression gauge, or electronically with an engine analyzer the measures cranking compression. With electronic testing, a computer analyzer estimates compression in each of the engine's cylinders by measuring slight variations in engine cranking speed.
