I was told by an engine builder to put a tiny amount of anti-sieze on the flange of the bolt head, that contacts the face of the cam gear. That makes it easy to break it free when you want to take them off. We all know how hard it is to break these loose.

I did it on my cam bolts and torqued them to 60 ft lbs. All I had was the torque to angle spec in the manual and the builder said he has torqued them all to 55 ft. lbs for years and has never had one come loose, so I just added 5ft lbs to that.

Food for thought

Glad they worked well for you! They really make it much easier to break those stubborn bolts loose.

In-lbs, definitely wrong. It's more like 75 ft-lbs from what I recall. Hold on...

72.4 ft-lbs

Edit: just realized this is ancient OP is asking about an AVCS car. ^^^Those are non-AVCS numbers.

Default AVCS intake sprocket torque

It's 22ft-lbs and then an additional 45 degrees...which equals out to 54ft-lbs, NOT inch pounds! I just did this yesterday on a 2010 WRX driver's side AVCS intake cam gear.

I had the torque wrench set to 54ft-lbs for the torque to angle and it was perfect at 45 degrees with a degree angle tool.

72ft-lbs is for the EXHAUST gears ONLY!! The AVCS engines use 2 different bolts is why. The intake cam gears use a hollow bolt for oil to flow through, hence the less torque.
