Valve Rocker Arm Bolt 19 N·m + 30° (14 lb ft+ 30°)
A GM dealer shows me another source, which says 32 Nm (24 lb-ft). Not sure which one is right but they screwed up my car.

I presume that you are connecting your Intake manifold to the cylinder head after replacing your intake gasket, if so they are 30ft lbs, and 360 in pounds. Hope that helps

Torque specs 2003 olds silhouette rocker arm 3.400


Here is a suggested updated torque spec for this engine's rocker arm bolts;
Rocker arms
Step one: Torque to 11 ft lbs then tighten an additional 90 degrees of bolt head rotation. Some guys don't fuss with the torque specs and just get them good and tight. Either way, be careful, as the heads are aluminum. You do not want to over tighten these bolts

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.

I need the torque specs for the exhaust manifold on a 2000 Chev Venture van engine size 3400 and... valve lifters @ t.d.c.


The torque for the exhaust manifold bolts is 12 ft. lbs. The rocker arms are to be torqued to 14 ft. lbs. first then turned an additional 30 degrees. Sounds kind of odd but that's how they tighten the rocker bolts properly.
