It must of gotten jambed somewhere and is totally hung up. If air does not work have you tried a long probe and a shop vac? I know you likely went with a magnet so I don't know what else.

Sometimes you have to just take a large breath and take it all apart and redo the work. It might be easier in the long run since you can spend lots and lots of hours searching for the washer. If you don't find it then you are never sure. My vote is to spend another two hours at it ; if it does not show then split the case, cleanup the adhesive, located the washer (take a picture of all of us!), and then assemble. It will give you a chance to check how well the sealant worked etc.

I had to redo my cam towers (both sides) after forgetting the aluminium baffles that are underneath the oil return tubes. As soon as I realized my mistake I had a few choices ; remove the new oil return tubes and use expandable ones ; undo the head nuts and pull the heads up off the pistons or redo the cam carriers ; I voted for the cam carriers since I could check the Threebond seal with the cam towers. In the end it worked out well and I only lost 4 hours...

Best of luck!
