    small oil leak from engine. Aged out of warranty. Repair tech tells me "oil is cheap!", meaning that I don't want to spend the money it would cost to repair the problem.
    Very irritated with Buick, especially since this engine has been around for years.

    crankcase seal needs replacement. Buick says pull engine and repair (likely also do spark plugs and water pump for parts only). Cost $2860.00

    my mechanic says they all do that. at least $2500 to fix 24hours of labor to remove engine and trans split motor and replace seal...he says if you're going to fix this best to change all gaskets AC compressor and other acsessories because thats the only way to get at and change those too.

    I went in for a tire repair and was told that they found a leak in the crankcase. It was a massive job that took several days to fix. It was very expensive. I was told it was out of warranty. I thought that modern cars were built better now.
