Oil coming out of my dip stick

[1fast95stang]

have no idea whats going on. I have a 1995 mustang, and just got done installing an ATI procharger. And now it seems that there is oil coming up out of my dip stick and spraying everywhere. Is this typical with a pressured intake system. or is this a different problem that i have. I have the PVC into a, T, one going back to the oil fill spout and the other going to a breather cap. Any one know what might be causing this.

your gonna either have to put a check valve in the pcv to it will not pressurize the crankcase or eliminate the pcv all together (better option imo) the check valve will also work very well at this, but a pressurized crankcase is badnews!!

the problem it is causing is that when it makes boost it starts pressurizing the intake and all the other lines that go off of it, if I were you I would get a check valve, these cars are installed with them from the factory in the line going to the cruise and one going to the brake booster to protect them, if you want you could go to the junkyard and get one from those locations and install in in there and that should remedy your situation.

check valve

doesnt the 95 mustang already come with a check valve built into the pcv system im not for sure on this, but i thought so

The PCV valve itself is "supposed" to be a check valve...but was never made to seal out boost. You can go to a stealership and pick up an OEM pcv valve from a turbocoupe or svt mustang which will keep the boost out of the intake. You will also need to be sure that you either have eliminated the vacuum line that runs from the throttle body to the valve cover or re-route it to the supercharger inlet....as that too will pressurize your crankcase.
