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 |

If that doesn't work, keep in mind that people swap out fans and some folks here have reported fans where the marks were wrong or flat out missing.
If this is the case, revert to the Capn's method. You don't even need to find TDC using the fan or distributor. Simply rotate the engine till one bank is showing three valves closed (one exhaust and two intakes - rockers will be "rocking") and one valve on the opposite bank is open. This is one TDC. Then if you rotate the engine 360 degrees around, the other bank should then have three valves closed and the opposite bank has one open. This is the other TDC. |
