ARP bolt tightening torque - niciou - 20-07-2016
Hi everybody
es that someone know the proper torque for ARP 1.9 td breech head
How newtonmeter ?
RE: ARP bolt tightening torque - Frosty - 20-07-2016
Pretty certain it's 100lbft, not sure what converts to in newton meters. I got it wrote down at work. Do it in 3 stages though. I'm sure someone will be along to conform for sure though.

100ftlbs is right doing it in 3 stages if you have the head off if not just go straight to 100ftlbs
RE: ARP bolt tightening torque - Frosty - 21-07-2016
Just had a look in by toolbox at work. It is 100lft which is 135nm.

you have an idea of the reliability of the cylinder head gasket with ARP bolts for a power of 180 hp is 1.6 bar
How kilometer before the seal silk Off ?
RE: ARP bolt tightening torque - Dave - 23-07-2016
I wouldnt expect 1.6bar to give you 180hp on a stock head.
Also MLS gasket with ARP studs shouldnt give you any head gasket issues with that boost unless you have serious VNT causing lots of low down boost / rediculous exhaust backpressure.
