The way I messed up was that I forgot I had the intake timing clamp on the camshaft and spun the motor by hand using a socket on the harmonic balancer.
It was tight so I saw the clamp on and removed it. Thinking I just tightened the balancer bolt what really happened was the vanos intake gear moved. The car never started up and I realized my error. So now I almost have the head off and want to do a leak down test before actually removing the head.
It has been running rough for a while and I thought it was intermediate levers. I had ordered and installed some different levers from a functioning motor and that seemed to help but still had uneven combustion. If the bottom end is good I will get a donor head and make 1 good one out of 2.
Any thoughts on this? Could the cam shaft be worn? Can I use a caliper to measure cam lift to verify. At least I am becoming an expert on the tear down of this motor.
