well long story short. Had a problem with a head stud stripped inside the block. Basically when i go to torque down the stud and nut it threads the stud out of the block. SUPPOSELY the shop put a heli coil in it and problem was fixed. Brought it home and problem is still there. You think that JB weld would hold up to the head in the block? im so sick of carrying the engine back and forth to the shop....espically in the TRUNK!@!! sucks....opinions? let me kno. thanks

 

I wouldn't trust a helicoil or jb weld for a head stud.

 

Definitely not.
Have it Helicoiled properly by a competent shop.
What do you torque your headstuds to?

the shop didn't put the helicoil in it then, or they messed it up when they did.

a helicoil setup is stronger than the original threads in an aluminum block because they have steel threads on the block to hook into now, and a larger surface area of the steel against the aluminum on the other side of the threads.

 

i was torquing it to 25 ft lbs!!!! it was spinning and not tightening...dam over and over and over. so fustrating.

 

That's sounds right. I have never had to have one in aluminum. I stand corrected. JB just sounds like a bad idea.

 

FYI, most of your aluminum race engines designed to be rebuilt constantly will have helicoiled studs and even oil pan bolts.. (damn those things are easy to strip!)
also look at brake calipers and other aluminum parts.. most of them designed for severe duty will all be helicoiled.
