If all the above problems are related to hydraulic lifters, Larry Bible on this site had a great suggestion that I have used with good success: Run a diesel oil in your engine for a few oil changes. Use a 15w-40 type. The diesel oil has better cleaning and oil impurity suspension qualities. It helps in cleaning older engines and their valve train.
