Hi John

Sound like I'll try to take it for a spin.

The sound didnt go away after 5 minutes of idle, and the engine
sputters a bit, like it has lost some power.

I can replace the hy-lifter without pulling more than the pushrod
tube,      valve train,  pop new hy-lifter in, put incollapsible
pushrodtube,  replace valvetrain?

Sounds good.

I could pull the rockecover, but I havent got a new gasket - willthe
old one break when I pull the valvecover?
