Gents, In the last 48 hours it seems that I have developed lifter noise. I checked my oil was a bit low (~1 qt) guess should have checked earlier..I guess. Anyway oil pressure reading good and even after topping her off full w/ Amsoil 0W-30 I still am getting lifter noise. Thoughts? Suggestions (Besides Should Have Checked your Oil!), Experiences? Thx cp
