Not pumping??

So THAT'S why it wasn't tight to start with!! The cupped washer was facing OUT when I took it apart!! Makes complete cense now!!!

Btw post #46 shows a pic of the key clearance.
Yup....it's good when such mysteries are solved. Can't tell for sure from the pix but it looks like the key will extend nearly through the thickness of the eccentric. The cam end should extend all the way through the eccentric when in place and a bit more. In that fashion, the center of the washer can compress all the way down to the cam end, and the washer cup's rim presses the eccentric hard against the gear face; that clamps the eccentric in place pretty well and the key is then does not have to do as much work for holding the eccentric in place..

And yes, the comments on the added washers vs the cam end play is right on, such washer stacking has to be done right if done at all. Check the end play on the cam once this is clamped right.

Did you look at the back side of the old cam gear and the thrust plate on the block? The thought is that with the old cup washer assembled backwards, the cam gear and thus the cam may have been walking forwards and backwards. If it the cam moved back a lot and this was in place for a while, then the cam lobes and lifters may be worn in together in a certain way, and tightening things up may move the cam forward (to where it shoudl havae been all along) and the wear contact points will change and the cam will now wear down rapidly. It depends a lot on how long this was run with the cup wahser backwards.

Don't mean to panic you! Anyone else's comments on that point should be heard too. Maybe you just put it back to gether right, hope nothing was worn differently, and see what happens. In some engines, you can pull up a lifter pretty easily to inspect for this but I am not sure on this one.
