Since my commute increased due to my work relocated, 400 miles per week up hill drive, 3000+ RPM drive Every week, I see 1.5-2 Tables Spoon of oil @ throttle body Oil Catch cans installed with limited oil amount of catch due to oil vapor from PCV Dual oil catch cans not an ideal result What else can feather eliminate oil trap @ throttle body? Feel free to advise.
I think you mean further, not feather? Although, I understand down feathers are excellent absorbent material for absorbing oil spills in booms. Check out my post, https://priuschat.com/index.php?posts/3200052 I use fine stainless steel mesh to specifically catch oil mist in the PCV circuit to the intake manifold. It seems to be pretty effective, much more so than just using the stainless potscrubber material alone. Posted via the PriusChat mobile app.
If it’s a cheap oil catch can, maybe trying another manufacturer might improve the catch? Dual cans do catch more, but in my experience, they’re mostly effective during winter, and the catch is maybe 80% water.
Another post here https://priuschat.com/index.php?posts/3208423 And more pictures of my mesh screens. I also reversed the manufacturer's suggestion of which port is the inlet and which one is the outlet, the side with the large mesh screen is my outlet. Posted via the PriusChat mobile app.
They are also potentially much more restrictive. If not kept clean, it could cause high crankcase pressures and potentially damage seals. Posted via the PriusChat mobile app.
I believe it is more important to provide as much surface area as possible for the oil vapor/droplets to condense and consolidate on, than it is to filter through a small size filter media. My stainless steel fine mesh filters are made by rolling up the mesh into tubes with 3 to 4 layers of mesh in the wall, then one end is flattened and folded over to seal. Then the resulting cone is filled with stainless potscrubber to further increase the available surface area. In use, the oil mist/vapor does indeed condense and consolidate on the mesh and potscrubber material, then gravity pulls the oil down to the bottom of the mesh cone to drip into the catch can. In this picture, you can see the oil at the bottom of the mesh cone (outlet side). The sintered brass filter in those expensive oil catch cans have a sintered brass filter with the surface area about the size of the face of a quarter. Posted via the PriusChat mobile app.
Thank you for everyone input I have a similar setup as xliderider's posted without mesh.. but my OCC has Sintered bronze and I've added stainless steel scrubbers in. I mounted the OCC below PCV that could be decease Oil Vapor trapping. Back on 3 months ago, my commutes were low, average 600 miles per month and most of my drives were used EV mode Now, my commutes are 3 x more and used ECO mode on high way drive.
Is anyone has used Provent 200 Oil Separator on Gen 3 Prius? It seems like it can separate oil vapor on
What prevents the flow from the inlet from going over the top of the quality steel wool sitting in the bottom of the catch can and out the outlet? Posted via the PriusChat mobile app.
Catch cans are not complicated. Decent ones use chamber size, a labyrinth/baffle path and/or media to remove oil from the vapor. My 'steel wool' is the same thing you call 'pot scrubber'. I'm curious about your photos in post 5. You say you reversed the manufacturers recommendation and made the larger port the outlet port. I've seen some that have a 'larger' inlet port because they had a bronze filter installed, was that the case with yours? You pulled that off and installed your mesh? You show the large screen mesh being packed with pieces of steel 'pot scrubber'. Last time I looked at one of these (and it's been a few years since my racing days) the inlet and outlet ports are completely open passages. You don't have any concerns having that material on your low pressure (suction) side of the can? Isn't that a bit like throwing loose debris on the throttle body side of your air filter? Are you going with the thought that it's relatively heavy and won't get pulled through? Am I misunderstanding your setup?
A good can with a baffle and why not just fill means more than a piece on the bottom But I have zero work experience with mass produced catch cans, so maybe they don't have a decent baffle/condensing/drain system
Here're the image of the current my OCC setup with steel wool and Sintered bronze. Weekly commute 400 miles and 1.5 -- 2 Tsp of oil trapped @ throttle body
My OCC is mishimoto. I'm putting it back as original Mishimoto OCC with Baffle and Sintered bronze and small amount of Steel Wool. I'll post back after 400 miles of High way commute on up hill drive. Average 2600RPM - 3100RPM showed in Torque
It's 80 mesh from Amazon: 304 Stainless Steel Woven Wire 80 Mesh 0.18mm Hole - About 11.8 X 39.4 inch Roll(30cm X100cm)- Filter Screen Sheet Filtration Cloth Fine Wire Mesh Posted via the PriusChat mobile app.
