Re: Leak testing HPOP system at 2500psi should it hold?
Many people experience hot no-starts. That means on cold oil the engine starts, but not after the oil heats up.
That is because cold oil is thick enough to not leak ,,,, depending on the size of the leak.
That is why air is recommended, but you have to do it correctly. You have to push all of the oil out of the system so the air can get to the point that is leaking. Sometimes that takes awhile. Lots of people don't wait to start listening.
If you see leaks at the injector top washer, you have an issue.
