Re: What is the jiggle test? 200 88

Start the car

Open the hood

Unscrew the oil filler cap but don't take it off

The oil filler cap should be held down due to negative pressure from the engine. If the cap "jiggles" or "dances" around, the crankcase has positive pressure and the flame trap is probably clogged and needs to be cleaned or replaced.
