cholag Posted May 7, 2008 Share Posted May 7, 2008 Hello, I am assembling my motor and I had my cam reground with delta cam and I now need to torque the cam tower bolts. But I cant seem to find anything in my FSM about the torque specs on those bolts. Also I had searched and cant seem to find anything.

z-ya Posted May 7, 2008 Share Posted May 7, 2008 You don't have a manual on hand that has the torque specifications? From memory the torque is 12ft-lbs on the cam tower bolts. Torque them like you would torque a head, start in the middle and work your way out. Quote Link to comment Share on other sites More sharing options...
zcarnut Posted May 7, 2008 Share Posted May 7, 2008 The cam tower bolt torque spec is not in the FSM. The text “How to Modify Your Nissan/Datsun OHC Engine†by Frank Honsowetz has 10 to 13 ft-lbs, so z-ya's memory is pretty good... Quote Link to comment Share on other sites More sharing options...
cholag Posted May 8, 2008 Author Share Posted May 8, 2008 YES YES YES YOU GUYS ROCK!!!!! I was going to guess and make them 30 or something, but while you have that manual open, can you tell me the torque spec on the hydraulic lifters that are also on the P90A head that I have.

z-ya Posted May 8, 2008 Share Posted May 8, 2008 If you torque them to 30 ft-lbs by mistake, you will most likely strip the threads in the head. The head bolts do most of the cam tower holding. Quote Link to comment Share on other sites More sharing options...
