Its a 65 chevy street truck, 350-350 turbo, I had a cam changed last year because the lifters were making metal against metal noises. It was great for a year then now in the morning it sounds like I am missing 3 quarts of oil until the engine warms up and the noises go away, sometimes it returns when I reve it up at a stop sign. The oil pressure gauge shows good pressure, should I just change the oil pump? what do you Chevy guys and gals think? thanks, Kool 65
