Hello Mario,

The problem that I have encountered with the faulty cams was discovered when adjusting valves.

After performing a valve adjustment, it was noticed that rockers for #4 cylinder had more lash at the rockers when past TDC for that cylinder, so check for that.

Since the engine was recently rebuilt, if it was cleaned properly it should slide in and out without to much effort once you have the end of the drive gear out of the oil pump re-enforcing ring.

Yesterday, when I was setting the end play on the 2 engines I am building, the drive gear would slide out slowly all by themselves when I had the engines turned upside on the engine stands and remember this is with the oil pumps NOT INSTALLED.

Of course I had cleaned and wire wheeled the shafts of the drive gears.

You are correct that if you want to service or check the drive gear bushing in the car, you will have to lower the crossmember to get the oil pan off.
