Default OK What the F' is this crap...

Since i bought my 2000 Trans Am, I have noticed that every so often i'll pop the hood and my oil dipstick will be raised slightly off the tube. So everytime i push it back on and the same thing happens.

When i got it dynoed at Thunder Racing i mentioned it, they cleaned the pcv thinking that might be the problem. Well they said it could be blowback, if the engine is worn down but i put 318/328 down stock. Of course while it was on the dyno the dipstick didn't move.

Anyway, i still have this prob every now and then, so what could it be?

That'd probably help with the diagnosis...

get a valve cover breather cap (replaces stock oil cap) and give it a try.

sounds like preshure in the motor.
i had a 98 gtp that was makeing a wierd noise like a belt squeek and it even did it with the belts off and i replaced the pcv valve and it still did it.
i for some unknown reason was under the hood messing with the car and took the oil cap off when it was started and the noise went away and there was a good amount of presure in there.
i fixed it by drilling a tiny hole in the oil fill neck right under the oil cap.
so eather that will fix it or a breather cap.

If a dipstick is popping up it is due to excessive pressure in that unit and it has to have somewhere to go if where it's going is not sufficient enough.

The drilling the hole sounds like a good idea. I guess i'll go to autozone and pick up a breather cap. Is this what you you guys are talking about?

ive never heard of it but try the breather cap idea. those are strong numbers so it doesnt lead me to beleive that something is seriously wrong.
