Continuing on my experiment to find out where oil is consumed, I inserted a glass jar in between the PCV valve and the intake manifold three weeks ago. The setup was described in the URL below.

Oil is still being consumed as fast as 1 quart every 400 miles, but now I begin to know where it goes. I can almost be sure that the oil control rings of cyls #1,2, and 3 are not doing their job--this I'll report in another thread. Here I want to bring my PCV experiment to completion by showing that the glass jar has not collected much oil after approximately 1000 miles, as shown in above photo.

I nevertheless like to keep the glass jar setup permanently (except for smog check time) since this is a good way to keep the inside of my intake runners oil free, and I expect the injector tips should be cleaner, too.Patrick C 88 750 149K
