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.

In the end, the plaintiffs claim the EcoTec 2. Thread Tools.

General Motors debuted this engine in , and due to its reliability, it remained until However, the engine has plagued owners with several problems; timing chain failure, high oil consumption, leaks, and high carbon build-ups. However, every engine comes with its glory and pitfalls. But if you want to get a ride with the 2. The 2. General Motors has fitted this engine to a wide range of compact and midsize cars.

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.

PCV plays an important role in engine efficiency, as it draws gas out of the crankcase, sending it through the intake manifold and back into the combustion chamber where it can be used.

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.

A Chevy Equinox Ecotec engine lawsuit alleges the piston rings, spray jets and PCV systems all contribute to oil consumption and engine damage. As complaints continued to pour in, GM offered a special coverage adjustment in May of A lawsuit says the 2. Drained the oil, and the oil that had been squeaky clean about 20 minutes earlier came out black as ink.
