We, walterolin and I, were trying to adjust the valve on my newly rebuilt engine tonight and we couldnt get the intake valve on #1 to loosen. We found TDC, 0 mark on the fan and #1 exhaust valve adjusted just fine. The problem is that I loosened the screw completely on the intake valve and I still could not get the feeler gage in there and it wouldnt budge (slightly rattle) when we tried to shake it by hand. Its REALLY tight.
After that we turned the engine so that the valve was for sure all the way open, and nothing. The screw is all the way backed out and its completely tight no matter what position it is in. What could cause this? My engine builder told me that he adjusted all of them to .006, so it obviously was correct at some point. At a loss here.. THanks |

Thanks. He did adjust the valves before giving it back to me, but I wanted to adjust them to be sure which is how I found the problem. If it really was an unseated pushrod, which Im not 100% sure of, maybe it happened in transport? Seems like a long shot.
I made sure to check the retaining wire, it is good. Also, pretty sure my dizzy is not stock since the previous owner megasquirted the car, which may be why he set it off. That should be an easy fix now. |

Its a good 1/4 inch difference. It was put in wrong, adjusted wrong. rich |
