Re: Valve Lifters & Tappets

Thank you Wes, for the benefit of your experience. I'm pretty sure that it was at least one of the causes of the tapping. Every lifter but the stuck one tested out beautifully with the "kick-back test". And actually, the stuck one seemed to have the right kick back as well. I was hoping for a dirty lifter to be the cause of my problems but I'm beginning to think that's not the case.

I also had a lifter with the exact opposite situation. When pulling the lifter, not only did it come out easily, it was coated with oil and there seemed to be space enough to wiggle the lifter in the tappet bore. Something tells me that shouldn't be the case. Perhaps that signals a broken tappet? After reading through all the threads, I'm beginning to think I've opened a real can of worms.
