The crown of the piston is always 1050-1100 degrees, boosted or NA.

Mr. Davis what is your thoughts on JB weld ontop of a piston. How really is it? 

Since we have a documented case of it working, I'd try it with a good measure of confidence.  It's the same theory behond why EGTs are hotter than the melting point of the head/piston with no ill effects - there's enough engine/mass to help thermally transfer excess heat away from the "hotspots" so bad shit doesn't happen.  

I'd use the 1000 degree stuff ktown posted up, though, if it were my labor.

Only time I saw JBweld fail

seen that a many times when people use it for radiator fixes

I've used it to fix cracked plastic radiator tanks many times. Just drill a hole to stop the crack from spreading, and JB it up. Our F150's been running a JB'd radiator tank for about a year, still not leaking.

i'm talking holes in the aluminum tubes

I have used JB weld to fix a rim that had a chuck missing from it before I powder coated it.  The rim reach a temp of 400F for 20 min and the JBweld help up fine.

Out of curiousity, what does a Rio with trashed timing belt sell for?  How extensive is the engine damage, usually?

bout 500 or less out here.

depends on mileage, options etc etc. I try not to spend more then 500 on one with under 80k miles and semi straight.  What you see in the pictures is about 75% on how they come to me. Sometimes I can clean up the pistons and slap a head on, or just replace 1 or 2 pistons. Really varies, I got the super hook up on parts, retail heads are 675, my cost is 430 (fully loaded brand new). They are not huge money makers for me. But they are so god damn easy to work on and sell fast. Someday I'd like to try and build one of these engines blindfolded.

 I know a guy who retired from working for the Wyo. DOT. buy Kia Sophias, Rio, and Sportags usually between $100 and $500. Then fix them and sell them $1,500 or more.

He helps me find Honda/Acura parts in JY and his other connections.
