    Head Gasket Repair after using Steel Seal

    I am new to the forum and this is my first post....I recently bought a 2002 Deville that had a misfire problem and multiple problem codes. I fixed the missfire (Front Coil Pack), and did plugs and wires. The car ran great and I loved driving it. One day this past winter my car overheated out of the blue and I had no idea why. It slowly started to do it more recently until now where it does it every time I drive it. I have done all the diagnostic work.. Thermostat, radiator serviced, chemical test.. and i have concluded that I have a bad head gasket. I started searching the forums for the past months for fixes and posts on replacing the engine. I finally concluded that the car is not worth the engine replacement so I am going to try to repair it. I have visited many sites and I may have stumbled upon a solution called steel seal. They have a Northstar Division and claim to have a 95% sucess rate on northstar V8's. The tech was very knowledgeable and explained why a special kit is needed to do the headgasket repair. He informed me that the thermostat malfunctions under pressure from exhaust gasses entering the coolant system from the head gasket breach. I am going to try their kit which cost 262.00 and is backed by a money back guarentee and if it works, ill post full details. I am going to add the URL's for their site as well as a link to a youtube sucess story. Anyone used the Northstar kit from Steel Seal before? Any Thoughts???

    Here is the link to the info page on the Steel Seal Northstar Fix.

    Re: Head Gasket Repair Data - Steel Seal

    This (Steel Seal and a host of other magic potions in a bottle) has been discussed in here, Seville, and Northstar Performance endlessly, year in and year out.

    The basic advice is: Don't use BandAids ........ repair the possible failed head gasket(s) properly. A BandAid might work for a day, a week, a month - but the Northstar head gasket failure is a constantly moving target. Study to find out why.

    MUCH info in the sticky posts at the top of the Engines: Northstar Performance threads as well as cooling system operation advice. Also up ^^^ in the top black bar "Cadillac Technical Archive". More info in Discussions, Cadillac Tech Tips.

    The thermostat does NOT "malfunction" due to exhaust gases in the coolant. Read the recommended threads/posts.

    If the 2002 Deville is in better than good condition, body and interior-wise, it's "worth" repairing. Repairs and maintenance do not factor into the "worth" of a car - that's cost of ownership.

    Yes. An insert kit or stud kit. If he explained it correctly, he must have told you that the problem is that the head bolt hole threads pull out, the head is able to lift, and the gasket cannot seal. It's a forever moving/widening gap, and CANNOT be sealed with magic potions in a bottle. What these products will do, is clog small coolant passages, and make a mess of the block and cooling system, making it harder and more expensive to actually repair the problem.

    He informed me that the thermostat malfunctions under pressure from exhaust gasses entering the coolant system from the head gasket breach.
    WRONG. An HG breach allows very hot combustion gasses into the cooling system, which overheats the coolant. The gas also stops coolant flow, since the water pump cannot pump air.

    I am going to try their kit which cost 262.00
    You'll be wasting $262.

    and is backed by a money back guarentee
    I'm sure it's worded so that it'll be very difficult to get your money back.

    Any Thoughts???
    Don't.

    You performed a block test. Did the fluid change color?

    It's your money, but I hate to see you waste it on this snake oil. Like Bass said, good luck getting your refund, cause it ain't gonna work.

    Re: Head Gasket Repair Data - Steel Seal

    if the price if the product was only $5 -
    I would have said it's a TOTAL waste of $5 -

    if you understood what caused the head gaskets to fail -
    you would understand WHY there is no mechanic-in-a-can product
    that can possibly work on a Northstar motor -

    here is the short answer -
    the bolts that secure the cylinder heads
    strip the threads right out of the engine block -
    so the bolts no longer hold the heads down tight -

    the ONLY way to fix the problem is to drill out the stripped threads -
    and install larger bolts - or special inserts -
    ----------------------

    read their ad - under The Solution - Step #1 -
    they claim -
    "Air pockets that develop while the engine is under high demand
    (freeway speeds) cause the thermostat to malfunction and close"
    that is NOT what happens at all -
    hot exhaust gasses get pumped into the cooling system -
    past the breached head gaskets - causing air pockets -
    the water pump can not pump air -
    so the coolant isn't circulated throughout the engine -

    it has nothing to do with the thermostat -

    ---------------
    and even if that stuff DID somehow
    plug up the current breach in the head gasket -
    the head bolts will continue to get looser and looser -
    so the breach will get bigger and bigger -

    ----------------

    and now you are going to say "but it is GUARANTEED" -

    well - it is NOT going to work - it simply CAN'T work -
    so - you MIGHT get your money back -

    but I will GUARANTEE that crap WILL cause additional problems -
    like blocking the PURGE LINE - heater core - and or radiator -

    plus the fact that it will make the job of PROPERLY repairing the engine -
    MUCH more difficult and expensive because of all the additional clean-up
    that WILL be necessary -

    IF you do in fact have failed head gaskets -
    a PROPER repair will cost between $2000 and $3000
    depending on where you are - and how it's done -

    if the car isn't worth that investment -
    cut your losses - and get rid of the car -

    ------------------

    by the way - SEVERAL cars have been MISdiagnosed with blown head gaskets -
    by "mechanics" through the "process of elimination" method -

    it's a Cadillac -
    it is overheating -
    coolant level is low - no external leaks found -
    BLOWN HEAD GASKETS

    when - in fact - the problem turned out to be a blocked up PURGE LINE -
    do a search for - and check the PURGE LINE -
    -----------
    THEN do a BLOCK TEST -
    that is the DEFINITIVE test for failed head gaskets in the Northstar motor -

    For the OP...

    I was eatn a gallon and a half of coolant every two days


    I once used blue devil for my 98Cadillac Deville to "seal" the problem

    It lasted 6 to 8 months

    Now my Deville eats 1 1/2 gallons, ( sometimes more ) of coolant every day

    So u can see... The stuff jus doesn't work.
