    GTO Intake Gasket

    I took my 04 GTO into the shop for an oil change. One of the mechanics said my intake gasket has failed, and that I was leaking oil. I havent noticed anything, i.e. oil, smoke, loss of performance, etc. When I asked how much oil, where the leak was, the mechanic that found the leak was mysteriously gone. Sooo, im not sure if they are taking me for a ride or what. Is this a common problem with Ls1? The motor is stock with a K&N filter. I have 75k miles and have not raced it (its a daily driver . I plan to wash/clean the engine down at start looking for a leak. Assuming it is bad, would now be a good time to upgrade my intake manifold? If so will a new one come with the gaskets that I need? Help!

    Does you car use oil? Does the oil on your dipstick look milky?

    Its not possible to have an oil leak from the intake gaskets on our engines.

    Exactly. I am wondering if they meant head gasket.........I really don't know what in the hell this "mechanic" is talking about?

    I don't seem to be losing any oil. My driveway is clean and the dipstick is not milky. I asked the mechanic if he meant the head gasket, and again said the intake gasket. I guess I need another shop to look at it?

    another option is it could be the oil pressure sending unit leaking maybe?? Either way don't go to that shop again because someone is either trying to milk some money out of you or they don't know these engines. Like was said before oil/water does not flow through these intakes.

    Mark and Orion are both right here.....but the bottom line is this "mechanic" does not even know what to call the "thingy doohickey"....so I would go to another shop friend.

    Its not possible to have an oil leak from the intake..... If any thing it would be a vacume leak from the intake.

    Im thinking if it is really leaking it has to be the timming cover gasket

    If it is coming from he intake area it has to be either the valley cover, the OP sending unit or yes...it could leak at the timing chain cover...but that would not be on top...I dunno......this mechanic is a dumbshit.....
