The engine may develop oil leaks from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

    A UPDATE --- I was told by A Cadillac Motor Division Rep, that My 2005 Deville Leaking oil was a normal thing... considering the age and miles, I was stunned by what she told me! I told her it was leakig from "3" diff. areas.. her response was "It's Normal for the age and miles!!! What answers for people that have spent Thousands on these oil Leakers!! SHAME C.M.D.

    It started at 97000, and continues to this time at 157,000 miles.
    Perhaps a class action would be in order with GMAC.
    It leaks and leaks, I do not feel its burning, but leaking from bottom of motor,
    the crankcase I think.
    Can we do anything or just complain and eat it?
    Does anyone have any ideas?
    I now use 3 quarts between oil change, which is cheaper than repairs at this time.

    From the first Northstar engine I brought, 1997 Deville , has cost me 1000's of dollars because of the many problems. The 2005 Deville I also have now also leaks oil and my mother inlaw also has a 2005 DTS that leaks oil.

    The question is: Who was the dummy that designed and who allows this engine to be put in Cadillac. After all problems you would hope they would fix this problem. But they don't!!

    I have owned Cadillacs starting with a 1959 though 1990 and never had problems. But now from the time they first install the Northstar engine they have been nothing but junk.

    I will never buy another Cadillac again.

    Steady drip from oil pan gasket. Quoted over $1,000 repair due to the labor involved. Tried gasket sealer liquid. Waiting to see if it works.
