tension settings for big end and mains

[Libran]

G'day could someone tell me the torque settings for the big ends and main bearing on a vp v6 PLEASE!!!

Con rod bearing cap bolts: 24-30 Nm + 47-53 degrees.

Main bearing cap bolts: 31-39 Nm + 42-48 degrees.

Don't use those specs of you aren't using new bolts

Yup, they're tty specs, try that with old bolts and you'll either snap em or they'll fail later when the engine is back together.

Sorry to jump in on an old thread. I've got a VY V6 3.8 Ecotec and am trying to figure out if I can reuse my rod and main bolts. But only if they fall into spec. Would anyone know the torque settings if they are being reused? Manual says that it's okay to reuse the side bolts as long as I put some gasket maker/sealant on them and give em a good clean first.

Also, would anyone know the correct bolt length specs so that I can compare them for reuse or maybe get them checked at the machining shop? I have a copy of the Haynes manual and the Holden FSM but stumped if I can find these specs anywhere.

For torque settings, the manual says;
Conrod bolts are 24Nm to 30Nm + 50deg
Main cap bolts are 70Nm - 360deg -> 20Nm -> 40Nm + 35deg + 35deg +35deg
Main side bolts are 12Nm to 18Nm + 45deg

Cheers if you can help
