anyone else have oil coming out of the valve cover (i guess cam cover since it overhead cam) gasket on the pasenger side? its going in on tuesday for fixing. im guessing the bolts were not tightened enough. And my rear pasenger side brake is makeing on and off bad noise. and wearing really weird, might be a little pebble there but ill get it looked at to then.

Its very little oil, but it seems like it squeezes out when i stomp on it and does almost nothing when i take it easy.

 

I would suggest taking that to the dealer.

if oik comes out like that, there could be something wrong with the PCV valve..

 

I actually just randomly had noticed the same thing tonight on my car.. I think I've seen a few other guys on here having the same issue before.. Dealer is getting a call from me tomorrow for sure

 

i checked the torgue of the bolts and the ones on that side tightened more with almost no effort. this looks like a case of gm under torqueing bolts again. and then when the warrenty runs out it blows and u have to pay a crapload to fix it. i suggest everyone check and take it in and get it fixed. im assuming that ill be needing a new gasket cause the damage may have already been done there plus the oil needs to be cleaned from under the gasket itself. so ya its going in tuesday.

 

both myself and Moepwr on here had the same thing... a couple twists of the ratchet and and we've been fine ever since.

 

What year is you car and what mods have you made?

 

I just had my car in for a leaking valve cover. I had spots of oil in various locations all around the seal of the cover. When I took it in to get looked at, the dealer said that the oil was seeping out. It took them about 3-5 days to get the new gasket.

If you plan on waiting for you car expect to be there a while. It took my dealer about 3-4 hours to complete this. I also had the recall for the charge piping done and had them look at my rear brakes.

Put about 150-200 miles on the car and I haven't noticed it leaking any more. Only time will tell if it comes back.

 

I know the question wasn't dirrected at me, but would mild mods play a factor in this issue? Plus not to mention you are a GM engineer so you asking a question about mods for a possible warrany job might make some folks nervous.. lol

 

09 hahn intake and charge pipe, dashdaq, water temp gauge and oil press gauge and american boost gauge. nothing much. thats all

 

He is just here to help like everyone else. I doubt he cares what people do to their cars because GM knows that some people will go aftermarket ASAP!

 

no they wouldnt, this motor is built tough and it shouldnt happen cause otherwise it would have happened to my sunfire with more mods than i had on this thing. its because of under torqueing the bolts. gm had this issue on the 3.4 motor on their mini vans with the head gasket. the only person i know where the head gasket didnt go is the one guy who knew about it and told the dealership to torque the bolts proper before he even picked it up.

His head gasket never blew and her is way past the milage where they usually did blow.

im not gonna keep it there for 5 days, they will see what the problem is, i already showed my mech so he knows about it, then if they need to order the gasket then ill bring my car back when its in, that how i do it. its not bad enough that its a problem so im not scared to drive it.

now i got to figure out what that rattle is under the dash by the passenger side a piller, on and off sounds like a loose screw. so anoying. gonna have to pull all my wiring i did for my ipod out of there to see if thats whats doing it.

 

Sorry I asked the wrong person. For oil leaks at the cam cover some mods can have a dramatic affect. If the mod changes the PCV how routing or the vacuum provided for crank case ventilation then yes. especially any turbo mod where the crank case vacuum source (part of the LNF turbo and not part of any aftermarket turbo I have seen) is changed. The pressure can then build up and cause any and all gaskets to weep.

 

Alright, fair enough, although I'm not trying to imply that he's like some scumbag spy infiltrating the forums for GM to undermine us all.. lol.. I was only curious as to why he asked about mods is all.. Maybe he knows of some mod that guys are doing that is somehow connected to this oil leak problem, and maybe not.. Maybe I'm just paranoid, and maybe not..

hmm, I have a CAI however I am still using the stock flex elbow connected the turbo with the case vent on it.. I just clamped my CAI off of that (right where the stock airbox clamps in) as to bypass any issues that might have come up down the road with the case vent.. Could the CAI be part of the issue even though I am using the stock flex intake elbow?

 

If the connection to the CAI of the PCV system is in the generally correct location and not restricted it would be ok. The really important connection is vacuum supply that is part of the Turbo. After market turbos don't have the supply and moving it up stram doesn't work the same. Also with increased boost there is increased blow-by and that inturn increasses the crank case pressure. All can add up to oil weeps at any of the gasket areas.

 

I have the same problem with my car but the dealer dismissed it as "normal"

 

It's in no way is normal for the oil to leak out..


Too much pressure is a sign of other problems. If it was just loose then it's fine. Tighten it, but if it's still leaking after after proper torque, the gasket is bad or there could be a mechanical problem.

 

I know I'm sounding like a broken record, but it looks like my VC is leaking on the passenger side too a bit. I have zero (0) mods to my car done.

Its starting to get easier to tell you where the motor isn't leaking oil from. Two of the local dealers have also told me seepage is "normal".

Really at a loss of what to do with this car. I've actually quit driving it for now and been DD'ing my Syclone. When you think your Syclone is more reliable than your Cobalt, you know somethings up Especially if you know anything about working on/owning a SyTy

 

Are you sure it isn't just old oil.

Spray nine will remove the exterior oil, then if it comes back you can bring it to the dealer and basically...

"Tell Them To Replace The Seal' because it is not normal for any new car to leak oil

 

My valve cover is weeping like this too.

Along with the charge piping braking, the rattle under the dash and a shot wheel bearing. My dealer is going to have quite the list when I finally bring it in for warranty work.

Car is stock.

 

Holy ****. That sucks.

 

meh, none of these things are what I consider a major inconvenience.

Just stuff that needs to be fixed, none of them are preventing the car from operating properly so it doesnt bother me.

What does bother me is the dealerships, they are a royal pain in the ass to deal with, hence why I have not gotten anything fixed yet.

When these problems are causing me more grief than the dealership will, then I'll take it in.

 

It's a new car. It should just work...

 

I agree.

Like ogc said, nothing MAJOR going wrong with my car... but the sum of everything is beginning to tire me. This strikes me as a vehicle that could nickle and dime us to death down the road.

Also, don't know about these other guys... but all of the oil I'm seeing is fresh. Especially under the high pressure fuel pump.

 

im sure its not old oil cause its running down the side and when i put my finger to the gasket i get a nice wet oil on my finger, and this is after i cleaned it off 2 times. took it in and they said they are getting me a new gasket and gonna torque it right. And my rear brakes apperently the inside pad is down to the metal already, the outside is low to but not close to that. 8 months and they are gone already?? is that normal, and im not even that hard on em, sure i went to 130+mph a few times and then had to slow down fast, but that was 2 times. but now im getting the basic pads in the back instead of high performance, they wont wear as fast and they are still higher end basic. lol he gave me a good deal, charged me $60 for full set of rear pads. that was something like 20-30 off

 

I just checked today and there is oil leaking out of my valve cover along the front and side? I will have to take it in this spring. My mods are Cia 3" catted dp, Synapse intercooler (just installed), dejon charge pipes, dejon sri.
