I need to order a new rocker for my 235(one of the rockers is a low pressure rocker with the internal groove lined up with the hole). When I adjusted the valves, it would shoot an 8 inch geyser of oil, over the side of the engine.

Looking at Jim Carter's website, there is left intake, left exhaust, right intake and right exhaust. I don't know which one mine needs.

The rocker in question is the third one from the firewall end.

Any help?
