Re: Rocker stud repair
ARP head bolts are to be torqued to 63# with their lube. I have gone to 70#, but I wouldnt go more than that. ARP studs are a bit more...80# with their lube.
That pretty much jives with what I remember doing.
I'm adding the 2 ft-lbs for RTV being used as a thread sealant.
Thanks for the offer on the head, Alex... I got my head back. I really need to start paying closer attention to voice mail, it was actually done around noon Tuesday, the day it was dropped off.
I had to wait on a head gasket anyway (should be here today, supposedly), so it really wasn't a big deal.
As it turned out, there wasn't ever a helicoil in there... what pulled out, was the original threads in the cast.
I suspect that the casting there was shaky originally, and too many cycles of stud removal did them in.
It was actually a good thing that it made me remove the head - I found the funky lifter issue, found an exhaust leak on the turbo flange, and found that my previous repair on the turbo drain leak didn't work.
Would have rather had a few extra days padding to get it all back together, though...
