  1. 5.3L Vortec 5300 Engine Oil Consumption

    From 2010-2014 GM's Vortec 5300 engine had multiple design flaws that led to an excessive oil consumption responsible for soiled spark plugs, bent pushrods, and timing chain wear to name a few. The problem was compounded by an inadequate oi…

    GM may have used the wrong bolts to secure the seat belts in certain 2020 and 2021 Chevy models.

    Could the new bolts work? Maybe. But when it comes time to rely on the seat belts, it's better knowing the right parts were used to tether them to the frame.…

    GM is recalling 850 vehicles with improperly welded fuel pumps.

    The automaker says the joint that connects the fuel pump’s outer housing to the pump’s flange may not have been properly welded by the supplier. Over time, the weld could crack and cause a separation of the high-pressure fuel pump from the flange, allowing the pump to oscillate inside the engine compartment.

    The oscillating pump can bump into a nearby fuel line and calamity ensues.

    The recalled vehicles include the 2018 Chevy Colorado, Equinox, and Malibu, as well as the Buick LaCrosse, Cadillac ATS, and GMC Acadia, Canyon, and Terrain.

    The Bosch fuel pump that Chevrolet used in a small number of 2018 models is moving and creating a potential fuel-leak nightmare.

    GM says the joint that connects the fuel pump’s outer housing to the pump’s flange may not have been properly welded by the supplier.

    That weld could crack and cause a separation of the high-pressure fuel pump from the flange, allowing the pump to oscillate inside the engine compartment.

    The moving pumps can damage a high-pressure fuel line which is going to create an even higher-pressure situation when you start spraying flammable gas onto hot car parts.

    GM owners are still trying to convince a judge that Vortec 5300 engines have oil consumption problems and don’t give owners adequate warnings when oil levels are dangerously low.

    According to the lawsuit, the Vortec 5300 engines in the vehicles consume extreme levels of oil because of defects in the oil rings that allow oil to invade the combustion chambers … The plaintiffs claim the oil pressure warnings can fail to activate in time to prevent engine damage, something GM has allegedly known is a problem with the Vortec engines.

    The judge had previously dismissed the lawsuit and doesn't seem too interested in complaints about fires, oil rings, or inadequate warnings.

    The plaintiffs have a small, uphill chance if they can amend their complaints.

    Well, that didn't work.

    Last year a very reasinable argument was made that the Vortec 5300 engine is designed in a way that creates excessive oil consumption. It's also designed in a way that doesn't warn you when an excessive amount of oil has been used.

    However, a federal judge has ruled there isn't enough evidence to support the claims.…

    There's something funky going on inside GM's 5.3L Vortec 5300 engine causing it to use a higher-than-normal amount of oil.

    Some might even say it's excessive. A lawsuit filed in Minnesota says the problem is multi-faceted.

    1. GM used low-tension piston rings that allow oil to leak out of the crankcase and into the combustion chamber.
    2. The rings, which are already leaking, are then overloaded by a spray of pressurized oil from the Active Fuel Management (AFM) system.
    3. Even more oil is being burned off after being sucked into the intake by the engine's positive crankcase ventilation (PCV).

    That's a recipe for disaster, but the cherry on top is the somewhat useless oil monitoring system. Instead of measuring the volume of oil left in the crankcase, the system measures environmetal variables to determine the quality of the oil.

    Sure, there's only a pint of oil left in the engine but don't worry ... the oil quality is great.

    The lawsuit mentions GM has tried to improve the situation by updating the vehicle's crankcase ventilation and active fuel management system, but it never really helped. Eventually GM just updated the Generation IV Vortec 5300 engine and replaced it with a redesigned Generation V Vortec 5300 that stopped using low-tension oil rings and reintriduced an oil level sensor.
