    2006 DTS - Oil leak ?

    Proud (partially) owner of a 06 DTS with what I've been told is a common engine oil leak. Apparently there is a shim with a seal on each side of it that resides between the block and the oil pan? I'm told pulling the motor is the only way to cure it. Is there any other solution?

    Re: Engine Oil Additive to stop leaks?!?

    Wrong forum. Your car has a Northstar engine. Please don't dredge up 9 year old dead threads that have no association with your car/engine.

    Moved from the 4100 Engines forum to DTS (2006 and later).

    Please see your PM Inbox - several ideas to look for. The halfcase reseal requires total engine removal and disassembly. Check the oil level sensor, oil pressure sender and oil filter adapter before you do anything else, and do NOT pour snake oil into the crankcase.

    The "shim" is actually the oil distribution manifold. There's a bit more to the Northstar than meets the eye. Take a look at a multi-year subscription for that car to www.alldatadiy.com
