at idle, you take the oil filler cap off a 95 hyundai accent 1.5L, and you can literally hear and feel air coming out of the valve cover...:lol:

also, nice metallic pinging sound, not all the time, but definitely there, and you can feel it when you have your hand resting on the intake manifold.

whats your bet on what let go?

oh i forgot to mention...the reason we found this out is because he brought it over to check the CEL codes, found a MAF code...MAF sensor wasnt even plugged in (for at least a few months hes been driving it this way)...

im thinking something got pinged to death. you can hear it more from the rear end of the motor away from the exhaust/valve cover so i dont think its a spring/springs, though thats possible

this has a 3/8" vac hose going right from the valve cover to the intake manifold....and its quite a strong push you feel coming out of it. it was too dark out to look for the PCV at the time but...i'd say it was more air than the PCV could ever move

With the MAF unplugged the car would just run in safe mode and run on the rich side.
How many miles are on the car?
