Sucessful Northstar head gasket repair in a bottle

[parts68]

trying it as I type
#3 cylinder has 75# so I seriously doubt it will work.
Just an FYI In mot counting on a permanent fix;
have a new motor ready when time will allow.

Parts68 - How did it turn out?

[twinbopilot]

1000+ miles and still no overheating

Congrats...I hope it lasts for you. I had a bad leak on my 90 Brougham and used a few things off the shelf including what you used...no luck. I hope yours is an exception

Blue Devil says right on the label "NOT RECOMENDED FOR NORTHSTAR ENGENS"

I tried that nanocrapology on a cracked Ford Model A block and it did nothing. Waste of time. They did however give me double my money back!

If these miracle liquids worked all that well, car companies would just bolt the heads to the blocks without gaskets and pour that crap in from the factory. It would save them a load of money. Gaskets are in the car for a reason and when they need to be replaced, there simply is no shortcut that can be taken.

OK. Mr. Coupe. Excuse my ignorance, but just out of curiousity, why does the engine have to be pulled in order to put studs in?

[submariner409]

Because there's NO room to work, especially on the rear bank of cylinders. You might get the head off, might be able to do the machining and drop in the studs, but you'll never get that rear head back on. No way can you rotate the engine enough to get rear head clearance.

3000+ miles later the engine started to overheat again as I was driving on the freeway. Oh no, I thought, here we go again, the fix didn't last after all. Towed the car back to the house and upon further inspection, the tensioner pulley for the water pump had failed! It wasn't the head gaskets! So I replaced the tensioner (very easy job - thanks to GM for a good design) and all is well again. So yes, the "Nanotechnology fix in a bottle" is still working....

sweet.

Makes sense.

The BS factor in this thread is too much for me to handle...
