Anyone every have this issue? There was a little oil coming out of the bolt holes where the intercooler bolts to my hard pipe. Towards the front of the car. I havent seen this before on my car and wondering if anyone else has seen it? I know on srts you need a catch can to prevent this but dont see where on this car would need it. Any idea?(group)

the only guess I have is the lube shop over filled my car by 1/2 quart. That might have something to do with it?
 
This is common I would think to get alittle blow by in the intercooler. Use to happen on my Subaru's too. I dont think its anything to be worried about.

your oil is coming from your valve cover>into the intake tract

remove the vacuum tube from the back of the valve cover that connects to your intake tube
plug or cap off the intake tube and install one of these on your valve cover
clean out your TMIC and hoses...problem solved

I figured that was what it had to be but looked in the intake tube and seen nothing. Ill try this. But it never happened until the over fill of oil. Must be the extra oil in the head. No biggie, I wasnt worried just curious if others were having the same issue. Its nothing compared to how much oil srts get in their intercoolers. s*** is crazy.
 
yea i never had oil in my intercooler either. As for htat lil crank breather filter. Its beed tested and datalogged that on the ms3 it scews of the short and long fuel trims. Its basically a no no mod.

Unsure about that, but Im just gonna put a catch can inline. No biggie.

yeah, my cars runs like crap now lol
did I mention I beat up on a MS3 last night....I attribute the slaughter to my lil breather mod(laugh)

like this?

don't bother...I've had it hooked up venting as shown and re-routed back to the vacuum source on the intake tube. Not enough oil accumulation to warrant the can ( the baby filter is sufficient )
try placing your catch can between your PCV and vacuum source on the intake manifold.....
 
How would venting open the PCV nipple on the motor screw with your fuel trims?

the back of the valve cover is not the PCV...it's a baffled vent
the actual PCV valve is located under the intake manifold>mounted to the PCV catch tank bolted to the front of your block

after you get a few thousand more miles on your MS3's pull your intake manifolds off and tell me you have no oil
 
I think the problem was just my car being over filled with oil. I dont think its a big deal. Im gonna add a catch can any how. ONce Im running higher boost levels. Say 22psi on pump then Im gonna want one anyhow. Thanks for the replies guys.

Ps. Are you being sarcastic about there being oil in the stock can or is there none?

hes being sarcastic. He's ALWAYS being sarcastic with a hint of condescending....

lighten up dude

although I probably use sarcasm way too much...I just joke around a lot

the facts are:

I can't confirm your oily intake tract is from an over fill situation.
but I would bet against that theory

honestly
to keep things clean pre and post turbo inlet
a catch can can be employed between the valve cover and intake tube plus another can between the actual PCV valve and intake manifold.
I didn't want two cans which is why I use the little breather on the back of the valve cover

to those that may think this is overkill I must strongly suggest you remove you intake manifold and inspect the inside and the intake itself as well as the intake valve area of the head. It's actually disturbing how much crap is in there after a few thousand miles of use.

The other culprit to oiling up the intake tract is the EGR valve but that's an entirely different story

adding a ctach can between your intake tube ands the back of the valve cover is a good idea and will not affect fuel trims as laloosh explained venting would cause

see that wasn't so bad and it was informative.
 
here's a pic of a MZR intake I'm porting
the EGR has been cut off - filled with epoxy
same for the VCTS butterfly holes

what promted me to do this was the oily conditions found when I had my intake off while removing the VCTS butterflys months ago
there is an insane amount of oil accumulation in our intake and head from the PCV and EGR

in a few weeks when I get this back from being powder coated....I'll install it and the oily mess will be a memory for me

This is common in the lightning. We fixed it by plugging one end of the PVC hose with a ballbearing and changing the PCV valve to a different type. As you raise boost, it will tend to pull oil up from the valve cover for whatever reason. On the trucks, it was really bad.. we're talkin 1/2 to full quarts worth.

Meth injection will solve this problem easily. If you dont need emissions, than you could take care of plugging the EGR setup. Just use common sense when you do it as you can create a lot of CELs and idle issues.
