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.

Originally for Equinox owners, the coverage eventually extended the warranty to 7.

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.

Figured I didn't have much to lose, and it would burn through 1 quart every miles. 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. Drained the oil, and the oil that had been squeaky clean about 20 minutes earlier came out black as ink. Refilled with fresh oil and a new filter, and I can report that after miles, there is NO noticeable change in the oil level.

Likes: 3, A Chevy Equinox Ecotec engine lawsuit alleges the piston rings, spray jets and PCV systems all contribute to oil consumption and engine damage. The following errors occurred with your submission. Anything else is the owners responsibility. 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.

Lower temeratures means less fricition.

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.

All times are GMT Refilled with fresh oil and a new filter, and I can report that after miles, there is NO noticeable change in the oil level. Soft Ride. And because that's not enough, it's widely believed that the Ecotec has a defect in its PCV system. RIT 77 Replies. Lower temeratures means less fricition. Less fricition means longer durability and increased performance. A Chevy Equinox oil consumption lawsuit alleges the 2. As you might imagine owners of all other model years with the same exact problem were less than thrilled. But the Ecotec's PCV may be vacuuming more than just gas vapors as it also allegedly pulls oil off the valve trains and into the intake systems where it gets burned off.
