I wanna pull a couple pistons to take a peek at the rings/bores/bearings

I'm know these motors use TTY and angle torque specs.

Can someone offer a general guideline on when it's ok to reuse any fasteners on these motors? mains, heads, rods ideally. My forum search has me more confused than ever...

Thanks for the schooling.

Rod bolts are okay to reuse. The ones I don't reuse are the head bolts.

I personally would not Re-Use Rod bolts...
they are a stretch to yield bolt....
once they are stretched into place....they are worthless if you pull them out.

new ones are cheap... just go buy some new ones


this also goes for Main bolts and Head bolts
unless you have bought specific ARP versions made to be reused in some applications...
do not reuse them.

I think TTY will forever be confused with torque angle tightening.

TTY is a type of bolt. The rod bolts and main bolts are not TTY.

duh.. I totally forgot the Rod Bolts and Main bolts on an LS are torque angle bolts not torque to yield

Jeez.. what a brain fart....

I kind of though you knew that! :-)
It is confusing for sure.
Balancer bolt is also TTY
