OK, so I am going to tackle the D.Vanos on my 3.0 X5 with 220K miles.
I am wondering what else I should do while I am in there. I have the full replacement gasket/seal kit and the valve cover gasket. I'll check the plugs and would like to test the cylinders for PSI. What should the PSI be for the 6 cylinders? BTW, what type of torque wrench do I need? Values: 80-120 lbft or
120-240 lb ft? Not sure. Should I replace the chain rail guides?
Thanks in advance for all your advice.
