If the overhead valves were out of adjustment, you can get some false positives.

Hey Rawze, how exactly does out of adjustment valves cause a false positive on an injector leak test. I've been chasing leaky injectors and I'm trying to figure out if I'm getting bad reman injectors or if there's something else going on.
Thanks

Because if the injector cam rockers are out of adjustment, they do not hold the injectors down in the closed position all the way ... making for a false positive on the test.
