This is my solid lifter that began tapping then knocking in about 4 Minutes before I could get it parked. got 1400 miles on the engine. I Drained the oil and strained it, no large flakes ,but a glittery tint to it . Checked the lift on the camshaft lobe and to my surprise it was only off by .002 .. Whats the best bet replacing just the lifter and crossing my fingers or new cam and lifters all the way around ? and is there any thing else I need to check to prevent this ? Not sure what caused it.Faulty parts..incorrect install..?? I have good oil pressure.
