I believe Randy hit it right on the head.

I changed out the rear two lifters and the problem has been fixed. My dealer had everything I needed in stock. That's a first for me with my 14 year old Evo.

I have adjustable pushrods but still had to loosen the rocker boxes in order to remove and reinstall the intake pushrod. Even collapsed it was just a little to long to come out. I think I will replace the front two lifters soon, just for peace of mind.

Thanks for all of your suggestions.
