OK, I got my car back a month ago new motor put 1500miles on it and finally raced somone(gt mustang) street race onmy way home from work. The Question is I have some oil that sprayed under the hood. Not sure where it came from, hard to tell. Any sugg. from the sts turbo experts?

 

When I first installed my setup I had the same problem!

only mine was caused by the dip stick popping up

I check my wiring and the pressure switch for the pcv diverter

valve had a loose wire on it. I think it pressurised my crankcase

for a sec and caused the oil dip stick to pop out. better

it did that than blown out a seal. IT REALLY MADE A MESS

and smoked when the oil hit the exhuast manifold!

which side was wet with oil under the hood? passengers

or drivers? mine was on the pass. side by the dipstick.

or maybe your divertor valve vented some oil under the hood.

the divertor vavle when under boost does vent to the

atmosphere under the hood or it might be excessive blowby

happening even though you have a new engine . that really

doesnt mean anything... Excessive piston ring clearances

will allow your crankcase to see more boost than the sts pcv

system can handle. it might be time to do away with the pcv

system or alow it to flow more or use a catch can !

some one did a write up on the catch can idea on here.

 

When you boost your car it needs extra crankcase/head ventilation. I ended up with a oil pan vent (-8), an air inlet for each valve cover, and an air outlet to a catch can from each valve cover, before I stopped having problems.

Do you have pics of that? Im really stumped on how Im going to set up my pcv. Do you think two lines from the valave cover to a catch would be enough?

 

Here you go:



You can't see the other side Inlet Filter or Catch Can fitting, but they are the same as this side.

Obviously not an LS1 but still applicable.

When I bought the Canton Racing oil pan, I had them put 2 extra 1/2" NPT bungs - One for blower drainback and one for breathing. At the front of the pan, because when you are really building cylinder pressure (acceleration) the oil is sent to the rear of the pan and doesn't get oil in the vent - very little oil comes out of the oil pan breather filter:



Now I see almost no crankcase pressure, which is really good for the ring seal, and I have enough case ventilation to move up to a YSI head unit for the track.

see what you got yourself into!!!

turbos are definatly not for everybody! even as simplistic

as our kit is i think the pcv system could be upgraded

with either a larger eletronic valve or do what he did above!

 

Thanks for the pics One question is ( does it matter how far you have the catch can away from the motor???) I also have a sts with a 422 lsx, But my concern is I want to run a set up I seen on here befor a guy used some home depo pipe ends and some fittings and hoses. but under my hood is crying for room I want to mount where the air pump was is this possible????
