Hi guys,

I found a small oil leak, driver side, engine oil cooling on my 2011 GC.

I think it is difficult, if not impossible, to know if it is only the gasket or the housing that I have to change.

Has anyone done the repair himself ?

I check the part 68211440AC or 68211323AB ; they looks similar ; anyone knows the différence ?

Thanks for answer
(sorry for my english)

My PCV hose was seeping oil and dripping onto the hose connecting to the oil cooler. I thought there was a leak there until I worked out where it was coming from.

It's the thick hose shown in the front of this pic. If you run your hand under it you will probably feel a bit of oil:

Yeah, mine looks the same, the PCV hose is right above it. As Lewy says, the hose will look a bit different to the pic I posted, because it has had a catch can installed to collect the seeping oil.

Ok, I'm beginning to understand, sorry. I don't have this PCV hose, and I don't see where it could connect to the oil cooler. Unfortunately, I don't think it would solve my problem because the leak is visible under the exchanger. Yesterday my mechanic told me to change the gasket, and he said me also that we can be sure that the cooler is OK only at the time of its removal:eek:

What do you think ?

If he's looked at it and says it needs replacing then hard to argue.

The PCV hose doesn't connect to the cooler, it just runs above it and it can seep then the oil drips down onto the cooler and looks like it is the cooler that is leaking. Easy way to check is run your hand under the PCV hose and the other large air intake hoses at the top of the engine bay. If you feel oil underneath it then it may be dripping.

Here you go, PCV hose, runs next to the air intake box and above the oil filter:



Mine drips from this air intake hose:


Just run your hand down under it:
