    2004 DTS Question

    I have a 2004 DTS with engine id JKB. A list posted here indicates this engine has the 1.5mm head bolts known to pull in the 2000 - 2003 models causing blown head gaskets. My car is about to cross 100,000 miles with my third party warranty expiring and I'm concerned about a head gasket failure. Is there an average when these head gaskets fail? From reading, it appears the repair would cost $3,000 plus and wonder if it's time for me to start looking for another car.

    Any advice would be greatly appreciated!

    --------------------------
    Is there an average when these head gaskets fail?
    NO - and before you ask -
    there is absolutely NO WAY to predict
    whether or not YOUR head gaskets will EVER fail -

    From reading, it appears the repair would cost $3,000 plus
    depending on where you live -
    between $2000 and $3000 is accurate -

    wonder if it's time for me to start looking for another car
    IF you are going to lay-awake at night worrying about it -
    OR stop driving it because you are afraid of "hurting" it -
    YES -

    get rid of it BEFORE you loose all your hair -
    or have a heart attack -

    on the other hand -
    realize that the pulled head bolts probably affected
    less than 10% of ALL Northstar motors ever made -
    so - the actual probability is very low -

    Thanks for the feedback. I was thinking this was more of a common problem with these engines.

    Thanks again.

    You may have the updated head bolts. The following post has some information on how to tell.

    I agree with Bass. Relax. HG failure is relatively rare in an '04.
