I'm afraid to say it. I might jinx it.It worked. I followed the procedure in your blog for making a groove in the pushrods to let air get out of the lifter and it worked.I drove the truck a bit yesterday and climbed some hills today and the ticking is gone.I hope this is the end of this phase of renovation so I can move on to other things. Like the from end,the gas gauge,the rear springs.---Thanks ---Jack
