ACDelco GM Original Equipment FC219 (12589430) Engine Oil Filler Cap

Great AC Delco GM Original part guaranteed to fit, great delivery, great part. One can't ask for anything else. If you work on your own vehicle, Amazon provides a great value.

This one fits right on my 2007 Chevy Impala.

Good quality

Fit my 2012 Chevy Equinox in an attempt to help the PCV system which, if plugged can contribute to rear main seal failure. Cap fit as noted by Rufus and was easy to install as expected. Time will tell if it helps the engine and will lower the rate of oil consumption that Ecotec engines are known for.

This has been good for my 2014 Chevy equinox seems to relieve the pressure as I can see some oil residue around the cap also have not had a p420 code this winter like I had last winter not sure it was the cap but that was the only thing I changed from last

Perfect fit for my 2012 Buick Regal. Seems to be venting as needed.

Worked exactly as advertised

Any GM vehicle built with the GDI (Gasoline Direct Injection) version of the 2.4L 4 cylinder Ecotec engine has an internal PCV (Positive Crankcase Ventilation) system which is extremely prone to clogging or freezing in temperatures below 32F. The stock oil filler cap is a simple, solid plastic unit which seals the crankcase completely. The purpose is purely to meet the required emissions standards, NOT for longevity of the engine.If the tiny passages of the internal PCV system clog with sludge or frozen moisture, pressure builds above the 1-2 PSI which major seals, specifically the rear main crankshaft seal, can withstand. Pop goes the main seal, out comes your engine.The FC219 oil cap is designed to vent excessive crankcase pressure above 2-3 PSI. Amazon says this cap doesn’t fit 2010-2017 2.4L engines, they are wrong. No, it is not original specification, however it is what NEEDED to be on these engines from GM. The FC219 is not a guarantee that the PCV system on these engines won’t plug and fail. The FC219 is darn cheap maintenance to try and prevent a blown rear main seal, loss of oil and engine failure. I bought on for my used 2017 Equinox three days after buying the SUV.One EXTREMELY important point regarding all modern GDI equipped engines- fuel gets into engine oil at a much faster rate than previous fuel injected engines. Fuel dilutes oil reducing its lubricating and dirt carrying ability. Gasoline in the oil also causes the now thinner oil to get past the piston rings leading to carbon buildup in the cylinders and on the pistons. Oil thinned by gas also causes excessive timing chain wear. How do you prevent this? First- IGNORE the “oil life monitor”, especially on GM vehicles. The OLM specifies far too long an oil change interval. Use only fully synthetic oils meeting the May 2020 API (American Petroleum Institute) SP specification which supersedes all previous including SN Plus. The SP oil is specifically formulated to combat carbon buildup and other issues in GDI and GDI turbocharged engines. Change oil and filter every three months or at a maximum of 5,000 miles. 3,000 if your driving is all done in freezing or lower temperatures. Second- Check the oil level every 300-500 miles when you fill the gas tank ! GM does not put “Low Oil” sensors in its engines. By the time the idiot oil can light comes on, the damage is done. Third- do not use any additives to API SP engine oils in GDI engines. Finally- change the engine air filter at least every 25,000 miles if you live where it isn’t dusty, and more often in dusty areas - like places where many truckloads of coal, stone and sand roam the roads. Maintenance is far less expensive than engine replacement!

Fits my 2017 Chevrolet equinox, I hope it helps to Avoid Rear main seal leak.

Le quedó bien a Terrain Denali 2016 motor 2.4lt

This is a pressure relieving cap. For anyone with a GDI ecotec engine with the stupid pcv opening in the mainfold that constantly gets plugged. Hopefully, this inexpensive fix will keep my rear main seal from failing. Item is as shown and fits the 2.4L ecotec engine valve cover opening. I still fixed the manifold problem, but this is some extra insurance.
