    Re: Sucessful Northstar head gasket repair in a bottle

    Bianca just had her HG's fail

    no bolts had pulled out
    just the gasket compromised mainly around one cylinder

    i didn't want to take the chance on putting some sealer in her just in case the bolts pulled down the road
    so we pulled the motor and inserted the block and put some bigserts in there

    she's all back together now and getting a test drive overnight and she'll be home tomorrow

    it has been nice driving a '13 cts in the meantime but i do miss her plush blue leather seats
    the cts is a bit cramped like a cockpit ... my only complaint

    Chris was it #1 that failed that's the main one I have seen, you did your self and the mechanic a favor by not using that stuff. I have had only three northstars that showed alum. on bolts when taken out. I have one apart now that they put the miracle juice in and let me tell you its nasty in there. I believe that alot of these failures are a lack of cooling system maintenance

    Re: Sucessful Northstar head gasket repair in a bottle

    yeah, actually 1 and 3 were compromised and 5 was starting to go

    the plugs looked fine though

    was running rough after startup for the first minute or so of running for a few weeks and then began to hydro-lock at startup for the last few days before i pulled her off the road

    my coolant was just recently changed out (radiator went this winter)
    had probably been 3-4 years since the last coolant change

    the new radiator leaked and was replaced a month or so ago
    then the water pump leaked and i got a new pump and the new cover design

    then almost immediately the rough startup began

    now i just need to fix the elc compressor ... gonna frankenstein mine with another off a car that has a bad exhaust valve
    my elc compressor lost compression and doesn't move any air the vac lines were totally crumbled too

    it doesn't drip anyway ... if it did drip then i would have had them do the reseal job

    Re: Sucessful Northstar head gasket repair in a bottle

    I was actually down there a few weeks ago doing a dealer trade on a GMC Terrain at Bob King and drove through the lot. Lots of inventory down there and saw a beautiful WD '13 CTS-V Glad to hear the car has been fixed and will be back on the road soon!

    yeah that '13 WD w/ black chrome grille and red calipers was a special order that the owner backed out of... we kept the deposit naturally ... it's been sitting for a few months as you might imagine

    Gorgeous car. We dont stock V's as they sit too long on the lot before we sell them. I can't remeber the last time we had one.

    i don't know the whole process but it involves suspending the engine from above, dropping the cradle and somehow getting the exhaust pipe out of the way

    Yep. Just passed 3,000 miles since my fix-in-a-can. We've moved to Mesa, AZ and we've had days over 115 with me idling in the heat and repeatedly accelerating to 40 mph and then stopping. I don't get it, but it's not giving up.

    Re: Sucessful Northstar head gasket repair in a bottle

    the only way that a fix in a can will work on these cars is if the gasket itself is compromised ... if the bolts are pulling out the fix in a can will not work because the head keeps moving away from the block with every combustion event creating a gap that gets worse and worse

    That uses the GM special "engine support fixture" J-28467B and the companion brackets and lift adapter. You basically install lift brackets, erect a T-shaped special brace and hangers over the engine, take out the slack, and then remove everything from the bottom of the engine - cradle and all.

    BUT - with the support fixture in place any work - any work - is impossible on the top - valve cover - side of the engine.

    Re: Sucessful Northstar head gasket repair in a bottle

    My mistake, just looked at it again... It's been over 4,000 miles since my fix. Started at 99,934 and now I'm at 104,040. I guess it's just a miracle or something, but it's running like a train.

    BTW, I found the most awesome Cadillac video ever. Go to Youtube and search "White Walls Macklemore." Loved it.

    ------------------------------------
    if your mechanic-in-a-can "fixed" the head gasket leak - for 4000 miles -
    than you DID NOT actually have a head gasket leak -
    it was simply misdiagnosed - like so many are -

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

    oh - and about that video - IT SUCKS -
