Bypass oil filters

PP sells a crankcase vent catch tank. I built a similar one in the past but neither put it back into the engine.

I do run a bypass filter system. I'm thinking it was made by filterKleen. Really keeps the soot out of the engine.

 

I think you might be confused on the names. A bypass filter is used on the oil that filters down to a smaller micron than the normal filter, but only a fraction of the oil flow goes through this bypass. If you are looking for a oil catch can for the crank case vent then like Flightline said, PP sells a crankcase "filter" setup. But you can build your own pretty easily or look in Jegs or Summit parts catalogs for crankcase catch cans.

 

Yes I made mine out of 4"PVC and couple Pvc's tees and end caps. The tee had 2"side going up to intake and exhaust. Then I line it with a soft gutter sponge. Couple of hanging brackets from oil pan bolts. I also painted it so it wouldn't look like white sewage line.
I left it off, when I put my motor back together this last week after a rebuild since I should have no more serious blowby.

 

I think it's laying in my garage somewhere, I wish I was better about getting pictures. I'll try to get a picture tomorrow. Difinitely nothing fancy.
I had approx. $12 in parts
