- If you have a stock-type air cleaner, or one with some restriction in the
- air filter element, you may be able to use the slight vacuum in the air
- cleaner interior to draw a small negative crankcase pressure. Run a big
- enough hose and use a filter element with low restriction. All you really
- want is to stop oil gobs and particles, right? A can with a foam or fiber
- element might do it. I'd suggest maybe fabricating a special vent outlet
- on each valve cover out of the way of most of the oil splash - baffled
- if possible. If you can pull from both covers, that'll improve things too;
- your only suction path is via the oil return holes, which have their own
- job to do. Too much air flow will help pool oil up top. Best of all would
- be to draw from the main cavity but that's something to save for the next
- rebuild...
