    Oil pan leak

    So after a routine oil change, my dealer detected what they called an upper oil pan leak. After ordering parts, I brought my car in for the fix. They've now had it for two weeks. Apparently, it's quite a job to disassemble everything to get to the seals in question. After five days, and a road test, they discovered that it still leaked . The tech had to re-do the entire job. I'm still waiting to hear back as to results and as to when my car will be ready. My previous DTS had the notorious half case leak. I'm beginning to think that GM can't build an engine that doesn't leak. The car has 28,000 miles. Has anyone else had this problem? How common is it? I'm not impressed that everything has been removed and re-done twice.

    Re: Oil pan leak

    Itís not as common as the old case half leak. The oil pan is sandwiched between the engine front cover and the transmission so front cover removal is part of the repair process and that is good amount of work on its own.
    A very efficient tech should be able to complete this oil pan job in a day or two. Then maybe a half day or overnight of letting the sealer dry before refilling the fluids and starting the engine. For an average or slow tech, itís a much bigger task and could take an extra day.
