Review on 🔲 ACDelco GM Original Equipment FC219 Engine Oil Filler Cap - Sleek Black Finish by Matthew Wheeler

Every GM vehicle built with the GDI (Gasoline Direct Injection) version of the 2.4 liter 4-cylinder Ecotec engine has an internal Positive Crankcase Ventilation (PCV) system that works at high temperatures is extremely prone to clogging or freezing temperatures temperatures. under 32F. The standard filler cap is a simple, durable plastic piece that completely covers the crankcase. The goal is only to meet the required emission standards and NOT the longevity of the engine. When the tiny passageways of the internal PCV system become clogged with mud or frozen moisture, the pressure rises to over 1-2psi, resulting in larger seals, particularly the rear main seal. Crankshaft sealing ring, withstands. Pushes out the main seal, your engine out. The FC219 oil cap is designed to relieve excess crankcase pressure in excess of 2-3 psi. Revain says this cap will not fit 2010-2017 2.4L engines, they are wrong. No, that's not the original specification, but it SHOULD be on these GM engines. FC219 is not a guarantee that the PCV system on these engines will not function or fail. The FC219 is darn cheap to maintain to try and prevent a blown rear main seal, oil loss and engine failure. I bought my used 2017 Equinox three days after buying the SUV. An EXTREMELY important point with all modern GDI engines is that the fuel gets into the engine oil much faster than in previous fuel injected engines. Fuel dilutes the oil, reducing its lubricity and dirt resistance. Gasoline in the oil also causes thinner oil to flow through the piston rings, causing carbon deposits in the cylinders and on the pistons. Gas thinned oil also causes excessive wear on the timing chain. How to prevent it? First, IGNORE the "Oil Life Monitor" especially on GM vehicles. OLM indicates that the oil change interval is too long. Use only fully synthetic oils that meet the API (American Petroleum Institute) May 2020 SP specification, which supersedes all previous oils, including SN Plus. SP Oil is specially formulated to combat sludge and other issues in turbocharged GDI and GDI engines. Change the oil and filter every three months or a maximum of 5000 miles. 3000 if you ride in the cold or in colder temperatures. Second, check the oil level every 300-500 miles when you fill up the gas tank! GM does not install low oil sensors in its engines. By the time that stupid oil can light comes on, the damage is done. Third, do not use API SP engine oil additives in GDI engines. Finally, change your engine air filter at least every 25,000 miles if you live in a non-dusty area, and more frequently in dusty areas such as the United States. B. in places with many coal, stone and sand trucks roaming the streets. Servicing is much cheaper than replacing an engine!
