This is a junk RX-2 engine with tons of blow-by.

 

This thing would fill a catch tank in 45 minutes.

 

It was needed for testing a new chassis so I built this mod into the oil filler tube.

 

Notice the downward sloped baffles.

 

Worked like a charm. No more oil blowing out.

 

The output tube to the catch tank was a piece of 5/8" electrical conduit.
