Hi,
what do you guys think of my minimalist oil catch can thinger? It's a fuel filter as you can see. I dont know for sure but I am not expecting more than a few ounces of oil between oil changes, but if I'm wrong I'll just extend/enlarge the clear hose which is basically the oil collector. It's baffled for sure. It also has a integral check valve, sort of, boost pressure is blocked a bit going to the valve cover, but I kept the original PCV in place.
For the intake hose side, I'm planning to just use a clear fuel filter for now to gauge how much oil really goes in there :\

 

I used a clear one for a few years between the valve cover and turbo inlet pipe. I think it was made by Fram for $2 at Walmart. It caught oil but not that much really. It seemed to trap any blow by well since nothing after it had any sort of oil residue on it.

So in conclusion, I'm not endorsing it, but I am merely stating my results using the clear Fram inline fuel filter as sort of a catch can between the valve cover and turbo inlet pipe.

 

cool. looking forward to putting some mileage on these. it would be nice if it would suffice. I just bought this unmolested IX and I really want to keep it clean
how's your AE86? I'm on club4ag. got a starlet that had a 4AG, hoping to get the BEAMS 3SG running

 

I did a boost leak test today at about 35 psi and these things held up, no problems. can't wait to put my car back together and test them out

 

Looks interesting, do you know what kinda of baffling is in it? I'd be worried that with a temperature range that is higher then fuel and the fact it is made for a liquid environment, if the filter is fiberglass or fabric material it may break down and get sucked into the manifold. Boost test is all good, but its not going to be seeing boost... vacuum is more of a concern. I'm interested to see how it works out. Maybe give it a month then cut it in half and see what the insides look like.... you may be on to something that could really help keep stuff clean and be super affordable.

 

These typically have pleated paper filters, just like the clear plastic versions. I'll open it up after a few sprints and an autox.
The 2 main nipples flow straight thru. The other nipple has some flow limiter one way and full flow the other way - this is my manifold side so that sees some boost pressure/full vacuum. I think the canister would see full boost pressure in 5seconds - I've tested it longer and higher pressures with the boost leak test. I am however considering adding an inline PVC on the manifold side

 

Make sure when you install to have the stock PCV or any inline PVC between the manifold and the catch can. Needs to stop boost from entering the can and allow suction to pull through the can from the valve cover. What I found to work well is the unscrew the stock pcv and attach a female 1/8th NPT - Barb fitting, this will allow you to keep the functioning PCV in place and attached to the manifold. Then a male 1/8th NPT - Barb screwed into the Valve cover location and you're all set to attach hoses.

 

That would work. I left the stock PCV and got another one. The threaded side does not see boost so I just screwed that into a tight hose.
Still no sign of oil. My lines slope upwards so maybe its going to take a while before any drop condenses in my filters . The install is pretty cute, not "I'm burning oil" look
