Hey guys
I do not know much about ATI blowers but I need some advice. My neighbor has a 97 LT1 355 A4 w/ an ATI blower. It is the self lubricating head unit. The problem is his intercooler is full of motor oil. Let alone the whole bottom of the car. I disconnected the hose that goes from the blower to the intercooler and their is motor oil in that too. How does motor oil get inside a self contained unit like this? Is their some line that connects the blower to the motor? BTW, he does have a "breather" on the valve cover. I read a thread once that opening the pcv system was not recommended for blown cars. Don't know if that is relavent to the problem though. He has also notice alot of oil loss on his dipstick since the problem.

He is probably pressurizing his crankcase. He needs to check his pvc system and some other stuff that I can't think of right now. Maybe later my brain will be working.

 

he is getting blow by. Also the oil came out of the dip stick because the crank case were pressuried. He needs to vent the pcv oil separator canister. He will lose oil every time he drives the car hard. They are few solutions to this problem. I sure someone will chime in.

is the crankcase connected to the blower intake at all ?

 

was gettng the same thing so I disabled my PCV system by unplugging it from the intake tube and plugging the hose coming from the pcv valve and plugging the hole left in the intake tube.

 

That was it. Thanks for the help guys. I sure am glad I dont have to clean all the oil thats under his car. He has like 8k in the motor and ran it around knowing this for months before wanting to look into it. It freaking every where. Geez.
