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 |

That's a good find, and it does happen, but as Steve says, if the motor was out, he should have caught it before sending it back to you. Also, the dizzy being 90 degrees off is very common, especially if you're using an aftermarket distributor. I know that the SVDA on my car is not clocked the same way as the factory dizzy, so my plug wires all are reordered to match the true TDC. Good job on getting it figured out!
The only other thing I can recommend is be SURE that you have the pushrod rube retaining wire seated correctly. It's almost impossible to see if it's in correctly without a mirror and if it's rubbing on a pushrod, it'll eat a grove into it VERY quickly - ask me how I know. |
