Help - Cam Nut Torque During Dry Piston to Valve Clearance Check
 

I am in the process of doing the dry check on piston to valve clearance on my on a 3.0 SC with 10:1 RSR pistons and a GE60 cams. As this is my first 911 rebuild I am following Wayne's book very carefully.

I have just completed the cam timing and everything seemed to go well with the 5.0 mm intake timing setting for both cams. I did deviate from Wayne's recommendation to torque the cam nuts up to final torque of 110 ft-lbs. I only torqued them to around 60-70 ft-lbs based on "wrench feel".

Since I will be disassembling the heads, cam towers etc to do the final assembly with the sealants and gaskets, I did not think it was necessary to torque the cam nuts to the final value just to check the timing and clearance. I can't see how cam nut torque would effect the timing for the cams.

Can I get away with this and torque the cam nuts to their final value only once during final assembly?

Your fine Tom.

Thank the lord. Tom, I'm at this same stage and was wondering as well.

Hey John - I just sent you a PM regarding the profile you did for me.
