I just received my oil air separator from Amazon.com! For 36usd it's a good price however it is just an empty can with no internal baffling to force oil droplets to condense!
Read on for how I fixed it!
Step 1: Opening and Inspecting!
Using an Allen key I removed the 6 screws. The top has 2 ports so close together that intake will quickly be sucked into the outlet!
The gasket on the cover is very minimal. The bottom of the can has a drain hole. There is a level sight along the outside.
Step 2: Extending the Intake.
I wanted the blow by gases to reach the bottom of the can. I used a spare length of copper tubing to achieve this.
Step 3: Baffling.
Using a piece of sponge I slipped in over the copper tubing. This sponge will force the oil droplets to condense.
Step 4: Reassembly!
I left the sponge near the top so the bottom of the can will collect the oil. I marked which was in and out on the ports.
Step 5: Drain Valve.
The kit came with a drain bolt but I want an easier means to release the trapped oil. With a nipple, washer and spare ball valve I made the drain valve!
Step 6: Completion!
There it is. My upgraded oil air separator. Took me only half an hour. My next instructable will be it's installation! Stay tuned!
