Hi Steve:
I thought your comments were very useful. Can you describe your "catch
can" to me and where you have located it in the engine compartment? Thanks,
Byron Fox
N3144C
Byron, the catch can I am using on my RV6 with a O-360 is a 12 oz metal can
with a screw off cap that is about an inch or so in diameter, similar to a
brake fluid can and attached to the motor mount with a couple of adel
clamps. I am getting 1.5 to 2 oz of blow-by in 25 hr of operation, my oil
change interval. Run the oil return line into the cap of the can with a AN fitting and drill
a 1/8 inch hole for a vent. I use a 3 oz veterinary syringe with a piece of
1/8" od alum tubing to pull the gunk (you would not want this stuff back in
your engine) and measure it at the same time. I routed the crankcase vent
to 1/4 inch over the top of one of the exhaust stacks to vaporize the
remaining oil mist and heat the vent outlet (these have been known to ice
up). The air/oil separator is the one sold by AC Spruce. Steve
