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 |

Got this one sorted out. In a fit of desperation, I took the rockers off, pulled the pushrods out and put everything back on, then it was OK. We then used the Krusty method to adjust the valves and TDC appears to be 90 degrees off.
Some help here: If the car is truly at TDC for piston 1, both valves will be closed (ie both pushrods will be all the way in and not extended)? Attached is an image down the pushrod tube BEFORE I removed everything which fixed the issue. |
