I haven't inspected the valvetrain yet. I'm leaning toward thinking the valves/rocker arms need adjusting or it might be a worn timing chain tensioner. The noise seems quieter in humid weather. I'm wondering if I can add an oil treatment when I next change the oil/filter that will quiet this sound? I don't want to damage the engine with or without introducing a product to the engine. I've seen mixed advice on several forums about the use/effectiveness of oil treatments. Is there a safe, effective product on the market made to help this? The engine has 70K miles on it and it consumes about a half quart every 1K miles. Thanks.
Adding OTC Oil Additives on a regular basis, when oils today have so much better detergent packs, doesn't make economic sense.
I think there are certain additives that can be used on a one time basis or few times basis to attack specific problems.
Otherwise, you're wasting your money.
