So I am trying to get my engine back in the car and figured it would make more sense to adjust valves with the engine on the ground. I have never owned a vehicle with a distributor or adjustable valves, So I forgot how this works. I started with TDC on #1 and adjusted valves to .008" which is the smallest gauge I had. turned the crank 90 degrees so the distributor would be firing #4 and adjusted #4's valves and so on. I got to the #2 cylinder and something didnt seem right. the rockers had way too much play and the adjusters wouldnt tighten far enough. I double checked my work on all the cylinders again and they all seemed correct...except the last cylinder. Is it possible that the guy who "rebuilt" my engine put in the wrong rockers or cam? Stumped.
