Yes, I'm serious. Yes, it's ghetto. No, I don't care.

I had great luck with something I think was called K&W Nanotechnology. I think it came in a green bottle? Worked great in a Saab 900 turbo I had about a decade ago. I made sure to follow the instructions on the bottle to the letter, though.

No personal experience but Blue Devil got some good reviews here a while back I believe.

Let me know how the bottle works on your Corvair?

Blue devil!

Fixed our e36 lemons car during a race, and held for the next 17 hours, full throttle, banging the limiter.

Then we didn't fix it right and lent it to another team (with full disclosure of said blue devil). They raced a full weekend no issues. Then they bought the car from us, and I know they reported at least one more full weekend no issues after that.

Pretty good I'd say.

Disconnect heater core will plug it up!!! I bought a civic that had been done very little heat.

This has me wondering if the Blue Devil will actually seal up cumbustion chamber cracks running between the intake and exhaust valve seats (aluminium head)???

Is this in regard to the M3 with all the dents you posted a while back?

If so... nothing is going to seal it. If the HG is gone it's gone between 4 & 5 and pumping compression into the water jacket.

E46 328i. Haven't seen the car yet or heard it run, just considering some options. Sadie the budget-friendly E36 M3 still runs like a raped ape.

Ours was not an m3, (95 325, so m50 motor), and we never tore it down to see where the hg blow was, but it WAS pumping compression into the water jacket. Blue devil fixed it right up.

Moms hubby called me a few years ago asking what to do with a Saturn they keep only because they can flat tow it behind a big motor home. I gave the Blue Devil recommendation. No problems since and I'd guess 30-40 thousand miles of normal regular driving by a guy in his 80's.

Blue Devil or K seal. I have used both and had good success with both.
