How well does JB Weld hold up submersed in oil?
That could be used for both the attachment and heat transfer

The overflow nipple (plastic) on my jeep broke a few years back

and

instead of buying a whole new radiator I decided to fix it with JB

Weld

and some alum tube.  It worked great for about a year until I

decided to

go on vacation.  Driving through the desert in 108 deg heat the

stuff

practically melted off (cracked and lost its seal and most of its
strength).  Soon I was out of water and overheating.  Spent 36 hrs

of my

vacation stuck in a place called 'weed' or something like that.  I

now

have a new radiator.

Probably good advice. I've never actually used it yet for anything.
Has there been any known failures from the intake port flow mods that

Bruce

and Tracy advocate on the six port secondarys? Or plugging small

vacume

holes on intake manifolds?
I would guess that port sees pretty close to 200 deg. while running.

JB weld is supposedly good to about 400 F; although I have my doubts
about that.  I mended a crack in the radiator tank seam on my van about
3 years ago, and it has held up just fine.  I also used it to plug the
holes in the tops of the rotor oil feed banjo fittings where I cut off
the vacuum line connectors.  Only a few hours on the engine for the dyno
runs, but its fine and looks the same as before the runs.

Were you careful about the mixing proportions Dave?
