'79 US 244. Owned it for less than a year, so still figuring out its quirks. The (incomplete) service history from the previous owner showed that the flame trap was replaced in the early 2000s, so I figured it was overdue for an inspection. I popped the hood and (for the first time) noticed that the PCV system wasn't quite like the diagrams I had seen. Presumably, the flame trap was relocated for easier service. What was a little weirder was the apparent lack of an oil separator box. A tube comes out of the valve cover and goes straight into the flame trap housing. There are two hoses coming off of the flame trap housing. The smaller one goes to the intake manifold and the other to the air filter box. Nothing connecting to a separator box. Looking under the intake manifold, there does not appear to be a separator box. Is this normal for earlier 240s or did a previous owner remove the separator box?
