Random lifter tick on a 2013 Silverado 5.3 with 48,000 miles. Dealer says they can't hear it and I have tried 3 different oils and it does not change. The tick is on the same side. Left Rear. Apparently I have super sensitive hearing or everyone else is deaf.
Since it says it will/can help with lifters i thought trying it wouldn't hurt?
ACDelco Engine Oil Supplement is a multi-purpose additive concentrate designed to help eliminate lifter sticking, reduce valve train noise, reduce camshaft lobe scuffing, and reduce break-in wear. The use will maintain the additive levels in oil to promote designed-in oil detergency, disperancy and wear protection, especially under severe service conditions such as high load and high operating temperatures. Not for diesel applications.
