ke,
My AERA software says:

Main Bearing Cap
(STEEL BOLTS 10.9) 15 FT/LBS, + 90° - USE NEW BOLTS

Connecting Rod
15 FT/LBS, + 70°, + 70° - USE NEW BOLTS, WASH & OIL

The AERA data is mostly from factory information so that should be correct.

You, good sir, are a f*cking legend.
Thankyou very much, now I can piss off this miserable little shitbox.
