Hello all,
I have a 2007 Chevy Tahoe - 5.3L FlexFuel engine with 170k miles on the clock. About 3k miles ago I switched from M1 5w30 High Mileage to LiquiMoly Molygen 5w30. For the past 1-2k miles I've noticed a lifter tick when cold - it does go away once warmed up. I am assuming this is a sticky lifter. In the past 10k miles I have run Kreen through the system twice, so I am questioning if any more additives will help. My plan is to switch back to M1 HM 5w30 and run AutoRX (figured I might as well). I've seen a few YouTube videos on spraying Berryman B12 onto the stuck lifters to free them...
Does anyone have any experience with this?
