I just got home from racing a guy and there is oil all over my engine compartment. I have an ATI DSC1 with 8 lbs of boost. What can be done about this and what causes it. I am new to FI so any help would be appreciated.

It's probably coming out of your PCV system, I have the same problem at about 8 lbs. Mine is now vented into a catch can. Hope that helps.

Read my Pics in my Sig to find how to setup the Catch Can... The problem is you pressurizing the block with your Blower.. Dont use a Check Valve. Just vent it all to a catch can, and run it to the open air like I do or run it back to the inlet of the blower.

I got everyting from everywhere. Are you talking about the Catchcan setup or my entire setup..

Get the Catch can on E-bay. A non Greddy catchcan like mine will run you 50 bucks.. Follow the instructions and cap off the passenger side of the intake. Get rid of the pcv system and run your catchcen to the open air like I do or run it back to the blower inlet, before the blower so it will suck, If you put your vent system after the blower at all your pressurize the block and keep popping up your dipstick.

I just run the tubes down under the car with no catch can on most of the cars we add force induction too.

I had the same issue on my old motor and it ended up being a broken ring galley.

God i hope it's not that. How did you finally know that that was the problem. What were they signs?

Thanks for the great info i will probably pm you when i go to hook up the the catch can system.

Just had the exact same problem. Tried the catchcan, breathers, bypassing the PCV valve... nothing.

Found out that 3 of the 8 pistons had chipped rings.

I take it this is a common problem for most forced induction setups. At what point of prs-boost dose this seem to happen. Is it just more common to higher boosted engines vs ones that keep it down low, say around 7-9 psi.

Is your oil dipstick lifting & spraying?
Where is the oil coming from?

I had my dipstick pop out as well 2 years ago. Turned out to the a hole on the side on the #6 piston.. Rebuilt motor!! Now my #6 piston is my paper weight in my office... I tell people this is what happens when you run too lean! Stupid ATI FMU and Stock Injector setup!!! Damn FMU was faulty and caused me a good chunk of change to rebuild my motor..

Yeah the dipstick lifted and sprayed oil everywhere. I am hoping that i don't have to rebuild the motor but it's not sounding good.

Yep, save all your Christmas money. I have been there as well, broken ring lands on 2 pistons. Let me guess, your car probably runs fine under 3500 rpms.....right, but when you get on it hard it probably chokes and loses some power and spits oil thru the ATI piping and maybe blows the dipstick out. I hate to see it happen to anyone but your not alone by any means. It's how us rookies learn.

When you rebuild it make sure to pressurize the oiling system before rotating the shortblock at all.....I'm on my second lesson after 500 miles on my new motor....this time W2W is building it!

As others have said in the past, do a compression test and cross your fingers.
