What Owners Say
"lobe prematurely worn for #6 cylinder. Had to replace top end"
Anonymous, BC (2010 GMC Sierra 1500 4.8-L V8)"It was leaking for 5 years before gm finally fixed it under warranty"
Anonymous, ON (2010 GMC Sierra 1500 SLE 4.8-L V8)"When engine was warmed up the oil pressure would drop until the stop engine light would come on. Have had it in the repair shop where they tried to fix it and were partially successful. It still drops oil pressure, but not quite as low so the stop engine light doesnt come on. The repair shop recommended a new motor soon."
Anonymous, MB (2010 GMC Sierra 1500 SLT 5.3-L V8)"Engine development a ticking noise at 190000km valve lifter failure. Which damaged the cam shaft. Cost me 7000.00 to repair"

"Lost cylinder vacuum. Mechanic recommended engine replacement or drive anyway. He suggested Marvel mystery oil swap with one qt oil at oil change. That fixed the problem for a couple years. Now the engine is hesitating again. Deciding whether or not to replace engine."
