Mike,

                I had to deal with a similiar scenario ( leaky O-rings in
collapsible pushrod tube ) I had a new stock tube and Bentley says you can
replace the stock pushrod tube by squeezing the ends to insert it in place.
I tried this and failed mightily, could never get the tube to compact enough
to clear the head. I spent hours on this based on Bentley's gospel. I
finally gave up and went to the FLAPS and bought 2 new O-rings for the
spring loaded pushrod tube. Problem solved.

                Also, David gives excellent advice on the reinstallation of
the rocker arms and pushrods.

Hope this helps.
