#105573 Hello first my english is not so good so I will try my best to explain my problem..
This problem happens to someone?
On a SIR head when I put all the cam holder on the cam and I follow all the torque procedure until 5e from the timing belt its all good ,the intake cam turn and exaust too but if I torque the first intake cam holder from the timing belt it doesn't turn anymore but the exaust cam continu to turn.
I tried an other set of cam I had and it's the same thing.A cam holder can be too tight? There is something to do with that?
If anyone have an idea your welcome!!

thx

#105724 No need to double post, my friend.

Cam holders can be torqued to hard, like everything else, enough to not let them move. if you go by the factory specs for cam holder torque, and everything SHOULD work properly.

Possibly a warped head, cam, or cam cover may also be the problem.
