    Re: Head issues. Dealer says i need new engine!! HELP!!

    EDIT: Waitaminute......what bolt holes keep stripping ??? What gaskets - head gaskets don't cause an oil leak - unless the head(s) are nearly falling off the car (overhead cam mechanism oil feed passages).
    ----------------------------------

    I believe GM had a standard TSB (Technical Service Bulletin) concerning the use of GM-approved Timesert bolt hole inserts in all 20 head bolt holes during Northstar top overhaul for failed head gaskets. I believe the thread machining and insert procedure is also called for in the GM Service Manual, at least it is in my 2002 Seville manuals.

    If the dealer tried to replace the gasket(s) without inserting the head bolt holes, and they have thread failure, it's not your or the engine's fault: it's the dealer using non-GM repair procedures.

    If push comes to shove, either you or the dealer call Jake up at www.northstarperformance.com - Jake is the manufacturer of Northstar head stud kits. Bulletproof.

    so how do i appraoch them about possibly not using Non-GM repair procedures?
    Do i just bring up the Northstar Performance Suregrip Stud kit and ask the dealer to contact them adn use them?

    Re: Head issues. Dealer says i need new engine!! HELP!!

    If they say yes, then the bolts wouldn't be stripping.

    Did you authorize them to replace your head gaskets, and get a price from them or are they just forging ahead on their own nickel if you will. If you drove the car there and they took this repair work on without you authorizing it, I would think they just bought you a new engine.

    FWIW I'm doing some snooping around on websites and can not find reference one to either Northstar block bolt hole repair or GM's use of Timeserts; it's like it all dropped off the face of the earth.

    The procedure for Cylinder head bolt hole thread repair begins on P.6-414 of the 2002 Seville manual.

    Re: Head issues. Dealer says i need new engine!! HELP!!

    I authorized them to do the headgasket repair and got a price after they told me that "Check Coolant LEvel" message on my DIC and leaking oil that i found on my driveway was casued by the headgaskets.

    I figured it be easy and done by now bc of all the info i've read on this forum.

    Re: Head issues. Dealer says i need new engine!! HELP!!

    Sub, as far as i can remember GM stopped officially recommending timeserts as a dealer repair (but why stop a good thing, right?)
    the parts from TimeFastener (the TimeSert company) in Nevada used to be a J-tool number, but one day a few years ago they changed the numbers
    and after asking the TimeFasterner folks on the phone they said that GM no longer 'approved' of the repair and that's why they couldn't use the same numbers
    (all they did was add BS, for BigSert, to the end of the J-tool numbers for the dowels and inserts and i guess that was good enough for GM)

    it might have been around the time the last 2003 engines were out of warranty

    Re: Head issues. Dealer says i need new engine!! HELP!!

    mrgoodbar, maybe you had a lower block seal leak and not a head gasket leak? if anyone had tried to fix it in the past (are you the original owner?) they may have messed something up down there and 'fixed' it so that it couldn't be truly fixed when it started leaking again

    Re: Head issues. Dealer says i need new engine!! HELP!!

    if they weren't using timeserts it would be good to know what they were doing
    tapping the heads and using inserts was the only repair that works (as far as i know)
    maybe they messed up and are trying to hide it
    how much $$ are you into them for so far?
    you need to get as much information down as you can
    maybe communicate via email if you can so you have every word they say
    don't make it obvious that you're looking to keep a transcript of what they tell you but it's always good insurance for the worst case scenario

    I wouldn't even mention Timeserts. Don't let them know what you know........yet. Just ask what exactly they did and why the bolts won't hold. Try to get something in writing.

    Re: Head issues. Dealer says i need new engine!! HELP!!

    WHY NOT JUST TELL THEM THAT I KNOW ABOUT TIMESERTS AND MENTION THE Northstar Performance Suregrip Stud kit....

    I KNOW MY ENGINE IS NOT F'D UP ENOUGH TO NEED TO BE REPLACED. ITS ALWAYS RAN FINE NEVER GIVEN ME PROBLEMS... JUST NEEDED HEADGASKETS REPLACED. HOW CAN "STRIPPED BOLT HOLES" AND JUNK THAT GM HAS APPROVED REPAIRS FOR CAUSE AN ENGINE TO BE REPLACED? THE HEADS ARE NOT CRACKED..NEITHER IS THE BLOCK, EVERYTHING INTERNALLY IS FINE....IM SURE OF IT BECAUSE THEY HAV NOT SAID ANYTHING ABOUT THAT.

    STRIPPED BOLT HOLES? GM HAS APPROVED REPAIR PROCEDURES FOR THIS, HOW CAN A CADI DEALER NOT KNOW ABOUT IT OR DO IT WRONG?
    IF THIS REPAIR HAS BEEN DONE MANY TIMES ON NORTHSTARS AND HAS WORKED, WHY WONT IT WORK ON MY ENGINE WITH ONLY 103K MILES, WELL TAKEN CARE OF AND NEVER GIVEN ME ISSUES BEFORE THIS?

    I FEEL LIKE THEY'RE TRYING TO STIFF ME...BIG!
    GET ME TO BUY AN ENGINE...REFURB MY AND THEN SELL IT. WITH THEM WINNING BIG.

    I FEEL LIKE TELLING THEM THAT I AM NOT STUPID AND WANT THEM TO DO THE JOB RIGHT.
    ...I TOOK IT TO GET THE HEADGASKETS REPAIRED AND THEY WERE GONNA DO IT.
    WHAT IF THEY SAY THEY COULDNT, CANT OR WONT FIX IT. PERIOD, AM I OBLIGATED TO PAY THEM FOR A FIX THEY COULDNT DO? I MEAN, THE CAR WAS MOST LIKELY IN BETTER SHAPE WHEN I DROVE IT IN.
