Oil vapor does decrease effective octane rating and can lead to knock, especially with the 6.4L. Ive also had a catch can (2 brands) on the car since it was brand new. Ive pulled my intake manifold twice in 30,000 miles and oil has been in the heads ports both times.

These devices are easy insurance for your high performance engine, and some builders use both a catch can and a breather tank. A catch can helps, but oil will still make it into the intake. Also any help installing a can would be helpful. I have a 2013 Dodge Charger V6 with the 3.6L Pentastar engine. I don't want to spend over 100 and still have to buy additional hardware. Any suggestions forum I want a can that comes with everything needed for the install. Importantly, breather tanks may not meet local emissions standards. I plan on returning the UPR catch can and getting myself another one. They capture some blow-by with a catch can and air filter, and they may have an oil return. In forced induction and racing applications, the build-up of crankcase pressure can be much greater, so a breather tank is designed to vent that excess pressure into the atmosphere. Some have a reservoir that needs to be drained regularly, while others are plumbed to return the oil to the crankcase. An oil catch can (sometimes called an air/oil separator) is installed between the PCV valve and the intake, where it removes contaminants and allows only clean air to return to the intake manifold. Normally, the PCV (positive crankcase ventilation) valve uses intake vacuum to relieve the pressure inside your crankcase, but that can result in oil mist and other blow-by contaminants building up on the valve and pistons, especially in direct-injection engines. Oil catch cans and breather tanks look similar and do similar jobs, but they serve different purposes.
