Dip Stick pops out

[balderman]

When ever I start the car the dipstick pops out about 6".. I can only assume that my crank case pressure is very high. What is causing that and what can I do to solve the issue?

Thanks for the help in advance

I had a problem like that once. I put in a rebuilt 351 that I bought from a guy cheap, it had leaks all over. As I corrected them I started having this same problem, what I did was pull out the PCV valve from the top of the valve cover and modify it to allow more flow. Mine had a little weight looking thing that acted as a baffle I think. I just cut it out so it could flow as much as needed, with the pressure I was seeing, didn't think I needed a baffle. worked fine for years. Don't know how the PCV valve is setup on a these cars, but the principle should be the same. I always wondered if the engine maybe had a blockage in it somewhere, or a gasket that wasn't sitting right, but, the car is still around 5 years latter and the guy that owns it now still hasn't had to do anything to the engine.

u could just need a new PCV valve. it's $10 and u can get it from ur dealer

The PCV valve is new. I had a larger on on when I fisrt put the mortor in and it was allowing oil to get into the intake. So we put int one that goes with a stock 302 motor.. and now no oil goes into the intake, but the dip stick pops up.,

I really don't care if it pops out a little, I just don't want to know if the extra pressure is going to cause harm to the motor.

I once had a camaro that the dipstick was rubbing the crank, and it would push it out. I pulled the dipstick out and there was a groove were it was rubbing. I would check your dipstick and make sure of that. I don't know why my car did that, so I can't really help you on that. It was a stock dipstick too...
