fluttering pressure release sound
I have a 2000 f150 xlt 5.4 engine, recently whenever I shut the engine off. Theres a distinct release of pressure with a plastic fluttering sound with it. Sounds like its from the PVC valve or that area. Could it be a valve leaking pressure past guides causing the little plastic piece in the PVC valve to rattle around.
Any Ideas what it might be??
I think I still have extended warranty coverage from when I got it last year, should be covered right?
