Its pretty common, I had it on my first Silvia, pukaasilvia has had it, and the owners mate of Nishan Tandoori in Hornchurch has had it as well. We got talking about S12's when I went to pickup some food.

It it worth replacing those bolts? Does it always pop near No1?

Chanced are you've snapped the shaft
snapped what shaft?
it did seem to tighten up alright, but i wouldent be suprised if it did pop out again, then it will deff need a helicoil, but i havent done any helicoils before so i dunno what i need/how to do it, ive probably got a mate who could help, but he's always busy.......

Snapped the actual rocker shaft that you are bolting down. I've seen them snap.

Its best to remove it completely and check for cracks.

Its an 8.3mm drill size...

if it hasnt snapped the rocker shaft you would be very lucky. check for hairline cracks in it. You need a m8 helecoil kit. Dont risk anything else.

I was lucky that my bolts although ripped out were just bouncing about in the stripped hole and not got jammed up inside the head.

Helecoil the lot. its very easy compared to doing exhaust stud thread replacements
