Hey guys, I will tackle it this Wed, just curious if anyone knows. Behind my exhaust manifold shield I have a tiny oil leak at the motor and it is leaking on my cat, burning up. The oil is NOT coming from the valve cover . I will be taking the shield off this Wed but what could be back there???


thanks
Ralph

If the line is not insulated, you might want to pick up a replacement. I think they started in 2013. It keeps the oil from coking the line from the heat soak after shutdown. If you're pulling the line, you're doing all the work anyway.

well guys, took the exhaust manifold shield off and realized that not only I have the updated oil feed line , it is also NOT leaking :(. Something between the top of the catalytic converter and cylinder head is leaking oil and it is not taking coming from valve cover. I tried to take some pics. I know there is some stuff next to the engine block but I dont know whata carrying oil or vaccuum. I would appreciate anyone help, Looks lik the exhaust manifold might have to come off.

Sure its not from a oil change. Maybe some oil dripped when the filter was replaced? Doesn't look like its fresh oil from your pictures.

having a hard time actually seeing the oil mark in the photo's. Is it to the lower left of the turbo oil line in the photo? I would check the oil fill cap for cracks. It's not shown in the picture, but it would be up and to the right of the pictures shown.

You will have to back up the camera for us to ID the linke on top of the turbo oil line. I believe it's coolant. The entire oil filter housing is an assembly, complete with a heat exchanger for cooling the oil. It mates to the engine block with gaskets, which could leak oil, but you would be one of the first on the forum with that problem.

The nut of the oil filter housing is 24mm, and a lot of technicians put this on with 1/2 breaker bars/wrenches. The gasket on the cap just needs to bottom out in the housing. I think the torque is around 12-15 ft/lbs. Less than a spark plug. In a hurry with too big of a wrench, and this could easily crack causing oil to drip down on the turbo.

Thank you all for the replys. I will look further into to. I am going to drive about 70 miles today without the manifold cover and see if there is fresh oil coming from. It is def oil that burns on the cat and stinks. I will verify the oil filter cap. I do my own oil changes with amzoil, I am not sloppy with them either. Talk soon

I had three oil leaks a couple months ago. They were all repaired under warranty. Camshaft actuators leaked, oil pan gasket leaked, pcv cover leaked. Have a dealer look at it. Most know what to do.

Pull the dipstick out and check the two o-rings around the seal. I had one of those rings break and it made a mess of my engine.

The car has no warranty and after what I experienced with two different dealerships I am done with them.

2012 1.4l turbo with 144k - I have had this leak for a few months, just came from under the car from doing an oil change and noticed leak coming from up by the oil filter housing bracket/holder.

I have nearly identical oil on my engine in exact same place. Searched everywhere for leak (just had oil pan resealed under warranty). Afraid I had yet another leak but almost 100% certain it is from oil change. Took awhile for oil to noticeably spread but even small spills can look like a big leak.

Hello all could it be coming from the oil cooler behind the turbo. Im have same issue cant figure out where its coming from also. I cant find it but i can smell oil burning while stoped at a light or idling. Everything is dry last oil change 1000 miles ago and still at full mark.

I am having the oil smell at idle as well. The dealership put a uv dye in my oil system and found two leaks. One from the oil pan and one from the oil filter housing.

Hey guys. I took my engine shield off from under the car and there was oil EVERYWHERE. Now, about 10k miles ago I had a bad valve cover gasket leak that was replaced under warranty but they never cleaned the bottom of the engine. I sprayed the entire underneath with engine cleaner and washed it/wiped it down. I am leaving the shield off for now and it looks like I was just burning up the oil that was on my engine. I will update you.

thanks again

Ralph,
Sounds like you may have a early Cruze model, those cars had a recall to modify the under car shield. All that oil is a fire hazard! GM recalled these cars and cut out a large section of that shield so the oil wouldn't collect there, apparently they had some fires as the exhaust pipe runs close enough to ignite the oil.

If this is the case I recommend you take it in and let them do the modification, it could save your car one day!
