2003 Pontiac Montana Question: metal gasket and cleaning out engine



Visitor, Jasper, AL, December 09, 2010, 11:44

The mechanic has told me that the intake gasket needs replacing and the engine cleaned out because coolant has gotten mixed in. He also recommended a metal gasket, because the old one was plastic and that a plastic one will eventually fail again and I will have the same problem again. I understand the need for metal over a platic one, but is cleaning the engine out necessary and should it cost $1,000 or more as he told me it might.

    gm has an updated intake set that will not leak as the old ones did. i would not vary from gm gasket.
    flushing the engine is a must as coolant in the oil will destroy the bearings.
    the price is a little high but in the ball park. we are at 985 plus any accessories it may need.

    Thanks, I thought I might be getting ripped but I'm not. It seems my mechanic is being honest. Sad for my pocket book though.
