New here just made an account to ask a few questions but I'll stick around for a little while. I have a 12 Silverado 5.3 LC9 114xxx miles. I had cylinder 7 throw a misfire code pulled plug and it was oil fouled. I'm getting the notorious litter noise. I don't know exactly how much oil it is consuming but I would guess at least 2 qts every 2-2500 miles. I guess my question is should I even worry about the lifters going out with that much oil lost and the cyl 7 plug fouling out? Or should I just save my money and put toward a new engine? I don't mind pulling the heads and putting lifters in but if it needs pistons anyway I guess I'm thinking what's the point.
