Tony D's Project corner (Oil catch cans) Part 2

[Tony Davila]

Below is both catch cans mocked up but not fully connected.


Finished oil catch can assembly.



From my testing which is not visible in the photos. I hooked up an evac system on the exhaust to pull vacuum to the canisters. I used a vacuum/boost gauge to test my work. What I found is that the exhaust system pulled about 3# of vacuum at idle and part throttle and at WOT created +1 psi of pressure. The mufflers created enough back pressure to render the exhaust as a viable source of vacuum at WOT. I was looking for a vacuum source at WOT because when at WOT the intake is no longer pulling vacuum and crank case pressure will build.

Test 2 - I decided to just use intake vacuum as my source and found that it was sufficient enough for the entire power range. I had created extra crank case breathing room when I installed the two oil separator canisters. I found out that this trip to BG only used 1/2 quart of oil to and from. Last year I had used 1 quart up there and 1 quart back. That is a 864 mi trip for me. The results are positive for me being that the crank case cannot any longer get pressurized under any condition. I believe everyone would benefit from such a device.
