#105572 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
