It's easier, the breather chimney nicely holds two SS woven pot scrubbers to separate the oil, plus they are "heated" so you don't get vaseline build up.rowster wrote:is this applicable to type 4 engines also? thanks.
I just redid my setup using some $2 1.8T PCV check valves... very low operating pressure, fast and high flowing for their size.
Work quite well, I use manifold vac and an accumulator setup to keep some vacuum on the case at all times, or at least for as long as possible, and one of the check valves is a dump from the 1/2 rocker box, only flows in case of pressure...
On a racing rig running at WOT constantly this would not work well without an additional vacuum source like the exhaust or a vacuum pump.
I have a vacuum break setup so I don't pull more than 5-7mmHg vacuum, it' purges into the 3/4 rocker box to assist the oil in getting back down to the sump.
I'll probably still end up with a Krankvent.
