Just installed new ARP head studs & a new MLS head gasket on my boosted LS... All went well, went to fire her up... 0 compression, just spins freely.
ARP studs are down to 62 ft-lbs, though I've heard to go to 65, 76, and 80.. Not sure which one to go Do but it felt like they were going to snap at 62..

Any ideas? Boosted LS in a 1997 EJ6 sedan..

 

Timing?

 

We marked the timing belt and cam gears before doing anything, but I'll check to see if it's lined up with the crank.. Hmm

Also, is 62 ft-lbs for arp studs too low? I haven't really found a solid answer on what to torque them down to...

 

no sparkplugs?

 

No compression? That's an automatic timing off.

 

Exactly, that's what I'm saying. Make sure everything is lined up at TDC.

 

0 compression as in u did a compression check or as in it won't start?
Not trying to by an ***.

 

Timing was off 90*, somehow. Fixed, runs great minus something fell into the lower timing / crank area and makes a clanking noise at random times. Going to fish it out tomorrow

 

good job on finding the issue
