    Spark ping on light acceleration is almost always EGR.

    If you did a successful 125 mile drive and WOT runs, you're good to go.

    Now clean up the mess and enjoy the car..............

When all else fails, read the instructions.......An e-mail to ARP might be enlightening.

    Think about it: If I use EOS, you use cup grease, Joe uses 10W-30, and Mary uses bear grease on a crankshaft cap assembly, whose torque reading is real, given the 4 different lubricants ? Torque does not, in any way, "tighten" a fastener. The required torque stretches the assembly (bolt/stud) primarily to assure even, repeatable, retainer and clamping pressures.
    Right, Ranger - I agree - I think that's part of the reason for the angular tightening specs - 120 degrees lubed is the same degree of clamping force/tightness as 120 degrees dry

    Re: Check out my Headgasket Job in the car!!!!

    update:2000 miles and holding temps around 200, with a/c on runs about 10 degrees hotter.

    I got a question, does anybody know of doing the headgasket job in a seville while the engine is in the car? Is their enough clearance in the back after tilting cradle forward.

    I know I know dropping the cradle is easier but im just not comfortable doing that and no garage so............what do ya think?

    I'm pretty sure the engine bay would be the same configuration and size as the one you just did, so long as it's around the same year.

    Re: Check out my Headgasket Job in the car!!!!

    Hey AAC,
    Thanks for updating. I have read over this thread and was wondering if they were still holding. I have a 2000 STS with 112k and moving to an apartment with no garage. Your thread gives me hope if my HG were to ever go.... By the way was wondering if you ever heard if this was possible on a Seville without dropping engine? Also was wondering if its possible to do above on a Seville with Jakes kit?
    Thanks,
    OSU411

    Re: Check out my Headgasket Job in the car!!!!

    whats goin on. Ya man you can do it but cant use jake's kit unless u drop the engine. But Norms is holding for me, if doing it in the car use norms because there pretty beefy. If droping the engine use jakes kit studs is the way to go, but norms works if doing it in the car.

    Oh okay. All I can do is laugh. I live in an apartment complex. Am I supposed to drop my subframe/engine/trans and leave it sitting in the middle of the apartment complex for the days it takes to complete the job? What about others in the same situation? If they do it in the car they can simply close their hood at the end of each day they are working on it......

    BINGO just shut the hood, u cant just shut the hood when its jacked up and what happens if it rains for 2 days not good for engine, maybe tarp it up...idk.
    In the car is a major PITA, but it is auite possible just not enjoyable.

    Actually most apartment complexes don't allow any work on your car. So it's possible they are going to tell you to stop.

    Re: Check out my Headgasket Job in the car!!!!

    Hello to all, 2 wks ago i was rear ended in my deville by a napa autoparts truck in a 45 mph zone and really messed up the car. So the insurance company said they can fix it for 2850$(ya right) and that the car is worth about 6K.In NC if the damage is 75% of the value then by law the car must be written off as a total loss. So im trying to get another estimate on the damage right now by a GM body shop. I really want them to write off the car so i can buy this 2000 DTS with 186K with blown headgasket.

    ? 1: Can the 2000 deville HG repair be done in the car?

    ? 2: How much should I pay the used car lot for the dts they want 3900?




    O ya btw i had put almost 10,000 miles on it since I installed norms, dogged the shit out of it before and after the repair and didnt lose a drop of coolant or overheat once so im going with norms again repairing in the car.
