09 Sedan here.
I am a spirited driver.
I was at injen, they were fixing my intake, and i noticed my intercooler piping had oil around the lower coupler, right were it goes by the radiator fan. I thought at first maybe its just water because of the rain during that week, then i wiped it off with my hand and noticed it was actually oil.

Injen tech told me that since the turbo is oil cooled they sometimes shoot oil through the turbo.

Then i went to a meet (dyno day in socal) and i noticed i was the only one with this problem...

Uhh... anyone else notice this? is this a normal occurance? lol... could be the other 8 maybe 10 turbo SS's didnt have it.

I havent taken the piping off to check it. havent had time.

 

No, Take it to the dealership that is not normal. That probably means the oil seal in the turbo is bad. There is no oil in my chargepipes. They are perfectly dry. It should not be PCV oil either there is no noticeable oil blow by on the LNF.

 

the turbo is not oil cooled, its liquid cooled, and i have a little bit on oil on the intake side of my turbo, im sure its not a blown seal but blowby over time collecting.

 

Oil shooting through a turbo is never a proper function....go to the dealer ASAP

 

the oil is probably comeing from the crank case vent hose, it happens. my talon did it, i thought there was a problem but apperently it is normal. whats why people put a oil catch can on the vent hose.

 

yeah my boss, whos been building the cars for a while now told me that its normal. just blow by, and yes our turbos are oil and water cooled...

 

There is no oil blow by normally on the LNF I drive really hard some times and all my chargepipes intake and IC have not even a film of oil in anything. He must have an issue with the oil seal in the turbo. I made a homemade catch can just to see and I drove it hard for a week stait and there was no oil in the catch can either. Gm has the LNF extremely well baffled so no oil gets by.

Trust me you are the only one I have heard of with this issue.

 

^^^ Like he said, I haven't heard of this one yet and have read a lot of posts.

 

Yeah mine are completely dry as well

 

crap i just dont want to remove my intake to take it to the dealer and then have them void my warranty...

i guess ill have to.

 

Your intake and any other mods you have have nothing to do with a leaky oil seal in the turbo which is most likely the problem. If the dealer is a PITA about it find another dealer.

 

dude its called BLOW BY all turbo cars have this problem!...my srt-4 had the same problem also---an oil catch can would fix it...the seal in the turbo aint badddd!cuz if it was u be blowing smoke at the exhaust constantly(black smoke).....the only reason u would get blow by.. is if u open ur car up...or u decide 2 do a couple of runs...then the blow-by would build up in the intercoolerpiping...if u drive ur car normally and barley openin it up of course it would be dry...i bet u money on it when u go to the dealer..they aint gonna know anything about it...because i remember when i had my srt-4 and i brung it in cuz i had the same problem they told me they didnt know anything about it....and they are still looking into it...but i read up on it and i made an oil catch can.. and it fixed the problem...the intercooler piping was so clean...only thing sucks if u dont clean the intercooler pipping it becomes sludge after a while..but i never had a sludge problem because of the catch can helping


plus depends on the dealer if they can prove that ur intake is the cause of the problem...then they can void it.. with no proof..they cant void it!! so all an intake does is make the car breathr better and in no way would that bring oil to the intercooler piping

 

no 2 motors are alike, so maybe u dont get blowby, but maybe he does, i know if ur in cold weather, and ur vent hose may be frozen when u first start it and u run it harder when the motor is still cold ur oil pressure can go up and past 100psi and u can get blow by. i had a clogged filter on the vent hose on my talon, and it was causing my oil pressure to go really high, i was getting blowby and oil comeout out by the oil cap and everywhere else oil can come out of. lol when i finally took off the filter everything went back to normal.

people shouldnt always scare everyone by going to worse case when its most likely just something simple.


take off the pipes, see if u got alot in there, clean it, run it another week and see what happens, if it gets worse or u got alot in ur pipeing/intercooler, then go to dealer. check ur intake pipeing, if u have oil in the intake pipeing upto where the vent hose enters, its blowby. check all the easy small things first, then look at if u have a bigger problem, that makes a good trouble shooter. otherwise u just make more stress and work for urself.

 

I took my intercooler piping off. No oil inside. I have no idea where this oil came from but the pipe inside is completely dry. LOL.

And the dealer does seem like a pain in the ass. But I found another one. The head mechanic seems cool. I'll take it there.

 

Could be from a recent oil change or leaking out of somewhere on the engine IDK. Check around the high pressure fuel pump.

 

I HAVE THIS TOO!!!! I thought I was insane at first... but I am somewhat 'relieved' (scared actually) that someone else is having a problem too.

So, the oil on yours, is it (like if you are looking under the hood from the very front of the car) the tubing on the right (which would be the hot side), or what? Mine is right by my ABS module, and I thought momentarily it was brake fluid leaking from that.

 

thats the spot, i checked the piping yesterday and no oil inside, turbo is completely dry...

and yes, the oil is right by where that spot, under the abs module right where you see the coupler.

i checked under the fuel pump, and yes there is oi. there, its dirty, doesnt seem like much but i can see oil residue on the engine...

crazy, an engine with 4600 miles already getting dirty with oil... i dont like that one bit..

 

Ok.. here is what is going on.. it is not a problem!!!!!!

Does everyone know that cool looking braided stainless line going to your actual intake before the turbo??? that line is coming from the valve cover, and what is in the vavle cover????


OIL! and when our turbos are making boost they are actually sucking air in(hard to believe i know) and since there is a line running directly from vavle cover to right before the turbo, it is inevitable not to get some oil in your intake track.


So no, it is not a blown turbo seal, and no it is not really blow by, it is just very tiny amounts of oil getting pulled from the valve cover, and over time it will build up.

Now, a "fix" for this is only available from one company that i have seen so far, which is dejon where they completely disconnect that hose from the intake, which is what i will be doing once i get my mods

 

read the previous post. No oil found inside intercooler piping. Anyways checked it again today and I'm completely dry. I guess I'll just have I keep checking.

 

Yeah, mine is ON not IN the piping. It seems to collect right around what looks liek a seam between the rubber hose and the plastic hose on the right side (driver's) of the engine compartment.

 

This is not an SRT4. You can ask anyone who has any knowledge about the LNF. We have no oil blow by unless there is a problem. Like I said they have the valvecover vent really well baffled so no oil gets sucked out trust me I used to have blow by issues with my LS2 I had to empty my catch can twice a week sometimes.

That sounds like your cam sensor or high pressure fuel pump area is leaking oil somewhere. that is not normal. Or maybe oil spilled on that area when someone changed the oil filter. IDK.


I will repeat myself. Unless there is a problem with his car there would not be oil inside the IC pipes. This particular motor has no blow by issues reported by anyone that I know of and I have read a ton of posts on here and another forum.

 

This is common, from what i have read here. i guess the o ring breaks real easily.. anyway, im gonna save myself from having to reinstall an intake haha...

 

Yes, quite a few including myself had the issue. Fix it yourself though dealership replaced my cam sensor and it still leaked so I used ultra black RTV on it and the high pressure fuel pump o-ring. No leaks anymore. There is a huge thread on it here. https://www.cobaltss.net/forums/2-0l-lnf-performance-tech-153/intake-camshaft-sensor-issue-153670/

 

See, the funny thing about mine is that there is no oil on or around the block or head. I haven't a clue where it is coming from, no traces anywhere else.

 

Maybe it splashed on there when the oil was being changed? IDK. Mine had a couple oil leaks that I found and fixed.
