Ok, here's an ongoing problem.
Whenever I drive my CJ5 long distances, it likes to fill the carb up with oil. The oil is coming from the PCV breather. All my knowledge and research points to some vacuum leak somewhere, but I can't find it. I've replaced the PCV valve, and, with the engine running, it has a nice vacuum to it. When I block that same tube, I can hear the engine speed change, which also points to NO vacuum leak. I've also removed the vacuum cylinder entirely at this point, since my current carb (a holley, w/ manual choke) has no need for it.
Anyways, yesterday, after about 40 miles of 65 mph, I downshifted to pull into the house, and it sputtered and spirted and stalled! I started it back up with my momentum, but it would no longer hold an idle! Pulling into the driveway got a big laugh from everybody, because all the oil in the air filter box was dripping on the hot manifold and smoking like crazy.
Today, it won't hold it's idle at all. Something's worse. I'm stuck. Help.
