I decided to try the slime fighter. It is an air oil separator that attaches to the the breather hole on the accessory case. The separator cost $100 and the adapter $20. the adapter is a 45 degree elbow from a plumbing supply store that has been ground down to accommodate a wrench. It could and should be home made for $2. The bad news is it does not fit. The above picture shows how the engine mount prevents the unit from being in a vertical orientation. The separator needs to be close to vertical to allow the oil to run back into the engine. I was the first RV-8 customer, but I am told it fits and works well on the RV-4,6,and 9 models. George, the designer is being very helpful and we are working on a new adapter to make the unit fit.......
For now, the unit is not installed. (See update Below)
4/6/02 -- Finally installed a modified unit in line on the
breather
tube. (Pictures Above) Craig and George, the designers were
helpful patient in their multiple design iterations to reach a
solution.
I am happy with the fit and installation of the unit now. There
is
still a fair amount of oil making its way through the unit to the
belly,
but it does seem to help reduce the mess a little. More info will
be posted as the unit accumulates more flight hours......
After 5 years an hundreds of hours of flight the verdict is in......
The Slime Fighter does not
work. After any flight, especially long ones, I have a little
puddle of oil under the plane after it sits for a while.
Inspection shows most of the oil is coming right through the Slime
Fighter and out of the oil breather tube. There is also a fair
amount of oil on the belly of the plane from in flight
accumulation. To be fair, I do have some oil leaking from
the prop governor, but the breather tube is the biggest
contributor. Oh, well.....
Belly after 50 hours is soooo oily there are drips of oil coming off
ther rudder. Puddle of oil after just one long flight
