Rick, I've got the twist type lock breather on the driver's side and I have the push in rubber grommet style breather on the passenger side...the kind with the nipple. That nipple has a hose running to the carb for PCV.
They have the black foam inserts in them and I've found that they got soaked with
oil and are now dribbling on my valve covers.
I soaked them in lacquer thinner which got a lot of the
oil out. They dried out quickly and I probably have another 5-600 miles until they start happening again.
I like the look of the round chrome Ford breathers, but they don't seem to last a real long time.
I was under the impression that the system WOULD work the way you proposed (and tried) but Jim has a good point. Would putting a closed cap on the other bank have the same net effect of plugging the PCV hole on the carb? (just the long way)....
I would like to eliminate the
oil splattering that starts every 5-600 miles. I have baffles in my valve covers.
Would like to see more on this topic! BTW, if you didn't read my post on the "coolant plugs" thread, the Evans stuff works like a dream. So does the fan override! SPF 1670 is now a reliable daily driver!
