Low compression test vs leaking injector

Low compression test vs leaking injector possibility in my thread (link) got no respect.

Check out link for fuel pressure regulator, leak down test that can spot leaking injectors.

Bad ring, broken ring, or bad bore is not the only potential cause. My low cylinder jumped all the way from 60 up to 175 psi with a good shot of Marvel Mystery oil in the cylinder. Seems like too much gain.

Let the engine cool down enough to remove the plugs and the wash down from a leaking injector is long since complete. Right?

Might a couple of treatments of Techron clear up the problem?

I replied saying disangage fuel system by pulling fuel pump fuse out and then starting the engine. It will work for a few seconds and then stop since fuel is not injected at normalized pressure. Then repeat the compression test. Have you seen that response?

yep, i guess its fuel wash also. way too much gain with the added oil to be a phisical problem.

Pulled fuse and ran engine to clear out fuel pressure. Wash down verified, or at least compression up to 150 psi. Wonder how many cars have been sold or engine "rebuilds" done for assumed bad ring when prob was wash down from reaky injector?

Im sure quite a share of them were put down without any respect. Im glad you confirmed this, great deal!
