Oil Dipstick?

[Kenneth]

I have a 98 camaro with 234000 miles on the car and a motor with 144000mi. The problem i'm having is that the dipstick pops out whenever I run it hard. It seems to run ok still. Any suggestions?

Check/Clean/Replace PCV?

Already done! Ever have a bad valve that seems ok but is messed up internally?

Not personally, no. With 144k miles, it's not outside the realm of possibility that the rings are getting shot. only thing that can cause a dipstick blow out on a stock 3.8 is excessive crankcase pressure.

Guess I better get the compression tester out. I'll update soon.

readings are cylinder#1-170, #2-165, #3-175, #4-160, #5-165, #6-170. Cold engine or at least it was when i was done! Hayes manual says 100psi min. with 30% difference from highest reading. I think it's ok but would love some input. Sorry for how long that took forgot I posted this.:work:

Did some research just now and it looks like my reading would have been higher with warm engine. Also opening the throttle would have helped alittle. Anyone have other numbers? like 220-250psi?

motor actualy had 164,000 now has 170-180,000 on it and strong as it ever was. Needs a 00-02 cam for that extra .008 in intake & .003 in exhaust lobe lift with the none log manifolds.

What you have is a blowby. I don't think those pressurize test will tell you the whole thing.

What I would do is for you to plug your TB hole that goes directly to your PCV. Hard it hard again and if your dipstick pops then you seriously need new rings.

It doesn't always blow the stick out though! You are probably right though it lopes a bit sometimes.
