I haven't adjusted my BJ8 valves in a couple of years. In the past I have bumped the starter with the solenoid but that is really hit or miss. I have never been able to turn the crank on the front of the engine with a bar but also did not take out the plugs when I tried. Shall I take out the plugs, put the car in gear and move the car to find the cam position for each adjustment. I have never tried this method before. Suggestions please.
