O-rings eliminate the need for gaskets and messy silicone which can make pulling the oil pan off a nightmare, especially when you’re at the race track. These captive o-rings pressed into our 1/2″ cnc-machined billet rails provide a tight seal and eliminate the possibility of vacuum leaks many racers have experienced.

Whether you’re interested in a street-strip pan or one of our professional series dry-sump pan, all of our pans at Jeff Johnston’s Billet Fabrication can have o-rings added for a small fee.

Our two-piece pan design comes standard with o-rings on all flat-sealing surfaces, including the top piece of the pan that connects to the engine block, and the bottom piece that completes the pan.
