Thread: oil leak

  1. #11

    Sounds to me like it could be leakng from the intake manifold, those neoprene gaskets are know to leak espically in the corners. I dont even use them, I use RTV and leave them out. Or possibly the valve cover gaskets, I just repaired my oil leak which was comming from the VC gaskets, thought I had a main seal leaking until I removed the cover and it was dry in there.
    From working in dealers for many years, i will say that they are hitting all the right spots, although they probably would have been farther ahead now if they would have pulled your engine and did a total reseal.
    Good Luck at the new dealer.

    No other dealer will touch it because of all the repairs even when it's under warranty

    This sounds like a job for the Ask GM Customer Service here on the site.

    We have another guy from Coventry RI on this site. He ought to come over to your house and fix it for ya! I hear he is a genius.

    I gotta go with Bigg Ron on this one. The rear of the intake manifold leaks whether you use gaskets or silicone sealer on them. Then it runs down between the engine block & the trans bellhousing making it appear like it's the rear crank seal or the rear pan gasket/seal. That's about all that's left that they haven't tried to repair yet.
    Serg, why don't you reach down behind the intake manifold & firewall, touch the joint between the mani & the engine block & see if it's wet. If it is, this is about the only thing that is that high that could be leaking.

    Hi sorry im 3 months behind, but My suburban is doing the same thing as your car. Did you ever check around the back of the Intake manifold and find a leak there?
