My chevy 350 had this problem for more than 10 years. Everytime I heard the noise return, I would change the oil and filter. But, I would substitute one quart of oil for a product called Rislone. Rislone comes in a yellow quart can found at most auto parts stores. It always worked for me. It is so inexpensive, how could you not give it a try?

no harm in trying it, the noise just started. he likes to blame it on seafoam.
thanks for the info!

I had the same issue with my jeep, my mechanic swears by changing to Rotella oil, it's one of the last oils that have certain additives that really help with lifters tapping. Just a suggestion.

Rislone has been THE #1 product to quiet noisy lifters for years. Any mechanic, shade-tree or otherwise worth his salt always has/had Rislone sitting on his shelf.

Good stuff.

If the Rislone doesn't quiet things down, try adding about 8oz of STP to the oil. It works in both the 4.6L engines in my LTC and F150 and worked wonders on my old Chevy 6.2L diesel.

You might try the STP before embarking on a Rislone clean-up....It's the less expensive initial try to quiet down the engine.

Of course one of the lash adjusters (lifters) may be messed up, in which case a diagnosis to discover the bad unit and a replacement is in your future.
