Chevy Cruze Eco Oil leake

Have you checked the cap of the oil filter? Maybe it has cracked?
I'm just guessing.

From what I saw it's fine. tomorrow ill get some hot water and dawn and clean the area and feel around the back to see if it's leaking.

Also check under the plastic cover. There are some cases that oil leaks from the PCV valve that is located on the cover.

Photos 1 and 2 indicate a coolant leak at the plastic connector above the thermostat.

You may be looking at residual coolant mixed with all the accumulated dirt.

Address that first before looking too hard.......and then clean/degrease the whole thing so you can determine if there is a secondary leak source......currently I don't think it is oil.

I just replaced the PCV Valve/Valve cover I will re check to mack sure no leakse but I used the proper torque spec and sequence.

A good point but I cant seems to find what that part number is. I will look harder or try calling a GM parts department.

You'll have to call the dealer...the part has been updated with a new #......comes with the hose.

I thought the throttle body leaks were related to the PCV system and failure of the check valve in the intake. The check valve in not serviced by GM parts except as an intake assembly that comes with a throttle body, intake manifold, and injectors. It's fairly inexpensive for what you get. I believe it's about $300.

Gus?

I am unable to figure out what question you are answering.......currently we are discussing the coolant leakage at the by pass junction and the need to address it (and clean up) before a oil leak can be pinpointed.

What did I miss?

OP didn't mention the usual issues with the broken PCV valve, and didn't mention the check valve when he replaced the cover for the PCV replacement, so I am inclined to discount oil leakage as the primary problem here.

It sure does. Members have had that plastic outlet fail as well as the top hose. So a coolant leak gets my up vote.

Then it is possible that the gasket of the Valve cover didn't sit right. I had the same issue. Oil leak after replacing the valve cover on the back of the engine, above the induction manifold.
The gasket was misaligned and it didnt seal properly, resulting in oil leak and engine light on (lean mixture if i remember correctly).

Fix the coolant leak first, replace the hose and water outlet with the newer revision parts.

After that's fixed checked the valve cover for leaks. I don't think there is much else on that side of the engine that may leak.

Dealership has the house I need it's 12 bucks they have 2 in stock. I'll ask to see a diagram of the area when im in there. I dont have any SEL code or a light. The oil filter cap is the cleanest thing in that area. I'll ask to see an exploded diagram when im at the dealer and see if there are any likely candidates.

Just bought the housing and the line. Going to try and remove the intake hose/MAF look like it would make life much easier to replace it all and track down the leak. It looks like there is a fair amount of plumbing and housings in that area that could be the culprit. Fortunately even though I live in the woods I have three dealerships within 50 miles.

My only other GM vehicle was a 99 Corvette and every "dealer only" parts generally started at 200 bucks so 40 is bucks for a proprietary hose and coolant manifold seems like cheap insurance.

Well looks like the oil is related to this issue:

I'm picking up the oil feed tube in the morning a couple quarts of oil and a gallon of collant and will butten the car up tomorow and update this thread. It this fixes it I will Edit the thread title to make it more searchable.

I dunno......with these photos that cam cover looks mighty juicy as well........gotta start at the top.....ya know, gravity and all that.

But you really need to get the engine degreased.....it is just too grimy to make accurate recommendations.....
I see a damp valve cover, a juicy trans line, lots of blowback, as well as the coolant dribble we saw earlier.

Get that puppy cleaned up before you go insane replacing parts.

I see that there is oil inside your throttle body indicating a stuck or gone PCV valve in your intake manifold. Also you might wanna check your innercooler where the charge pipe connects to it. Oil will backflow into your charge pipe and down to your intercooler.
Did you wipe up your TB before taking those pics? I had oil leaking at the charge pipe and TB connection. With clamp as tight as it could be it would still leak out onto my transmission. I bet youve had that leak for a long time.

That's not oil it's coolant that splashed in there it was clean when I pulled the cold air pipe.
