Ouch, anyone have some Mecurochrome to put on the stab wound in my back? Must have not use a sarated knife as I don’t feel any pain. I guess I was right when I said a loose adjuster nut was the cause of the problem. He never mentioned that the nut was loose in his original posting, as he now states. He’ll be back, as a guest so no one knows, just to see if i reply. Sir, the part is called a tappet not lifter (tappet is solid and a lifter is oil filled) and I doubt it was stuck. If the tappet was stuck, as you state, there would need to be a cause which you have not addressed and the problem will reoccur in the future. As for your apology, I doubt it was meant for me so I’ll just go find someone who can understand 70+ year old humor.
