Dealership called last week to say truck has failed lifter(s). They would need to tear it down to see the full extent. Gave several possible repair options, two of which were repairs, and depends on if it’s just lifters or rods and camshaft, etc… 3rd option is a new engine.
What is the likely hood they can accurately diagnose a failed lifter with out tear down? No engine codes, and my Blackbear tuner diagnostics only show a couple random misfires that never go beyond a counter of 1 but quickly go back to 0.
truck has always had some sort of tick, but dealer while under warranty always said it was high pressure fuel pump and / or vacuum pump.
fast forward to last week, son ran the truck down to almost empty, filled up with 93 octane, and about 20min after called me to say he can now hear a loud tick driving(now can be heard inside truck with windows up.
im definitely not interested in repeating this with GM lifters/rods/cams just to have it fail again, nor do I want another GM with the AFM crap.
Trying to decide if I roll the dice and have a local performance shop to the AFM/DOD Kit, with a chance there’s other damage like metal shavings from camshaft other other parts impacting bearings and such
Other option is a Jasper remanned 6.2L with AFM/DOD delete. 13K installed but has 3 year 100K warranty.
truck currently has a slow rear main seal
leak, and was quoted in the past 1800-2400 dollars due to labor involved, so swapping engine would also solve this at no additional labor cost.
i guess one other option is maybe a full rebuild with AFM/DOD delete, but reading this might be more with labor cost and less warranty
thoughts/opinions?
