Acetylene or Propane plus Oxygen is much hotter, works WAY better.

As said--heat the plug, not the casting.


Tried that once. Enormously too much oil along with the refrigerant. Messy as...

Dinosaurs all died 65 million years ago. Ten years on processed oil doesn't seem that much by comparison.

Not what I'd expect. I'm not in a position to challenge B&M, but I'd have expected 170--200 in the pan, not in the cooler return-tube. Many modern cars have transmission temperature sensors on the...

.031625 X 1.5 = .0474

I don't think it's anywhere near as critical as some folks have made it out to be.

How much lifter plunger travel do your lifters have? I've seen OEM lifters with more than a quarter-inch of...

That's .031 at the adjuster nut. Not .031 at the lifter plunger where it matters. You're not taking rocker ratio into account. The lifter plunger is being depressed more than .031.

3 psi is probably insufficient.

The gaskets aren't soggy because the fuel level is too low.

What you have going for you is that there's three needles 'n' seats instead of one. More-or-less...

I'd expect that would lower volume, but not pressure. May be so slight that you'd never notice.

Pressure is set via the internal spring.

Oldsmobile restricted their heater supply, so did Chevrolet.

No promises on Buick and Cadillac, but my guess is that all GM divisions restricted the heater core flow somehow. Either a small hole...

Totally depends on the geometry of the headers.

First Guess: Not likely due to the width of the trans bellhousing where the torque converter dust pan attaches.
