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. Those gaps allow oil to sneak past and burn up in the combustion chamber. To make matters worse, the Ecotec engine uses oil cooling jets to reduce piston temperatures. Lower temeratures means less fricition.

That last responsibility falls on the oil control ring which is found at the bottom of the control ring stack. The following 2 users liked this post by Silverado They might make an allowance.

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. General Motors and Sanchez v. General Motors. According to the lawsuit, the Ecotech engines can burn one quart of oil every 1, miles which causes engine knocking, low oil pressure, fouled spark plugs, damage to the timing chains and eventually engine failures.
