ARP…235 ftlbs. with their moly lube unless you want a damaged crank snout.

 

I use thread inserts, helicoils and make my own taps like pictured. I know the problem is already solved but I really doubt you would have ever fixed those threads, being that those threads were messed up on the end of the bolt it would have torn up every thread on the way out.

I wouldn't worry one single little bit about using a time sert, they are just as strong if not stronger than the original threads. I've used them several times to repair spark plug threads in cylinder heads and they hold better than the original threads.

 

Thank you. The Time-Sert seemed to go in well and the bolt bit and torqued so we'll see how it goes. I hope it holds up so that the engine doesn't have to come out and be torn apart. I'll try not to worry about it.

 

The tension of the bolt will keep the time sert tight, just like when you put ARP studs in a motor.. you don't tighten them at all, just finger tight, but the tension of the nut pulling on the stud keeps the stud tight against the threads and in the motor.

 

Also, the bottom of the Time-Sert expands and stakes itself on installation, and is installed with red Loctite on its outer threads.
