Thanks for the ideas, guys. I guess I should have mentioned that the lifters are in fact solid. I haven't been able to pinpoint the exact lifter, but it sounds like it is either on the #5 or 6 cylinder. I don't think it will cause problems, but it is just real annoying. One of these nice spring days I'll recheck my adjustments, and I may look into that Delo oil. Thanks again!!
