A properly functioning crankcase ventilation system is key to making sure your engine stays a happy camper. In a factory style setup the OEs use what is called a Positive Crankcase Ventilation system rather than just venting it out to the atmosphere. They do not cost horsepower, are simple and clean and are the system I recommend for anyone that isn’t building a race car. That’s why fittings like these from Earl’s are so good, because they help you keep a PCV system working properly, even on your modified LS engine. Hell, they are universal for other systems as well.

Earl’s knows how important the emission system is for modern vehicles. The positive crankcase ventilation system is crucial for the proper operation of your engine. That’s why we developed a push-in PCV fitting for LS engines.
Machined from aluminum and coated in a durable black anodized finish, our PCV fitting fits into the OE grommet hole, replacing the stock PCV fitting without any modification. Originally designed for LS engines, it can also be installed on any system that utilizes a ¾” i.d. PCV grommet in the valve cover.
Simply choose a fitting with either a -8 AN or -10 AN male flare and connect it to your PCV system with the appropriate adapter and rubber line.
