She was in storage for 5 years and I had to replace the engine. The shop installed a remanufactured Powertorque engine. I never heard of Powertorque, but they remanufacture engines sold by OReillys. The engine comes with a 3 year 100K mile warranty. I’ve had the engine for 14 months and 16K miles so I’m well within the warranty period.
It doesn’t leak oil. Its burning oil through the tailpipes. It smokes on startup for about 5 seconds, but not every time, about half the time. It loses about a quart of oil every 1,000 miles, which is double the acceptable oil consumption rate as per GM bulletin #01-06-01-011I. I would understand for an older engine, but this one only has 16K miles.
The engine runs smooth and I don’t notice any loss of power. I opened a warranty claim and took the truck to the local GMC dealership, where they checked the PCV system – no trouble there. They think it’s a problem with the exhaust valve stem seals, but they don’t want to deal with it: the Powertorque warranty only pays a fraction of the repair cost.
I pulled sparkplugs this afternoon. Each plug has a clean side and a side that looks like a burnt marshmallow.
From what I’ve researched online, it could be valve stem seals. I’m planning to replace them. But what if that doesn’t work – what else could be causing my Powertorque engine to burn oil like that?
Any thoughts?
