2.4 ecotec oil consumption fix

GM made updates to its 2. As the crankcase's oil level drops owners experience bucking at low speeds, engine knocks and ticks, fouled-up spark plugs, and irreversible damage to critical components like the timing chain. And it's all made worse by an oil level monitoring system that doesn't do a darn thing until it's too late. There is good news, however, as multiple settlements have extended protections to certain owners. Let's take a look back at how we got here. GM switched to direct-injection for the 2. The new design relied heavily on low-tension oil control rings, spray jets, and a positive crankcase ventilation system to lower fricition, increase efficiency, and boost performance. Each piston has multiple control rings to maintain compression, transfer heat, and keep oil out of the combustion chamber. That last responsibility falls on the oil control ring which is found at the bottom of the control ring stack. As the piston moves up and down, the oil control ring scrapes oil off the cylinder walls and prevents it from exiting the crankcase. But the oil control rings GM chose are way too thin and wear down quickly allowing gaps to form in the ring's coating.

Yeah, unless you're barely over. The policy is for oil consumption.

The 2. General Motors produced this 2. At the basis of the 2. Like the original 2. It has a cast aluminum cylinder block with a highly rigid lower crankcase a reinforced "Gen II" block. The engine block also features direct-mounted accessories. Early engines were equipped with GKN forged connecting rods. In July , GM switched to C70 forged connecting rods. Engineers introduced into the block design piston-cooling oil jets. Oil jets or oil spray squirters continuously spray the underside of each piston, increasing longevity by reducing engine operating temperatures.

The class action alleges defective piston rings are prone to premature wear and excessive engine oil consumption that causes damage to the Ecotec engines. The consolidated class action lawsuit arose from three separate actions: Berman v. General Motors, Hindsman v.

The engines also contribute to the oil consumption due to spray jets that spray oil onto the piston skirts and cylinder walls. This allows even more oil than normal to sneak past and faulty or worn rings into the combustion chamber. Received 23 Likes on 19 Posts. Their focus is on safety-related issues. This time dealers are told to diagnose the problem and replace the pistons. Send a private message to Soft Ride.

While previous bulletins only offered software updates to reduce the recommended oil change intervals, TSB C acknowledged oil consumption as an issue for the 2. Ran it at RPM for 15 minutes after it reached operating temperature, kept an eye on the oil pressure light and listened for strange noises. Also doesn't seem to be getting as dark nearly as quickly as before. Please consider creating a new thread. Advanced Search. GM switched to direct-injection for the 2. Less fricition means longer durability and increased performance. Quote message in reply? Their focus is on safety-related issues. Major class action law firms use this data when researching cases. What could have caused the 2 connecting rods to be damaged? And because that's not enough, it's widely believed that the Ecotec has a defect in its PCV system.
