    OK this is my 3rd Oil Catch Can (OCC) procedure conducted in 5 weeks. This time on my 3rd 2010 Blue Prius w 217,000 miles. This is a solid $24 OCC aluminum product, a bit heavier for my tastes, but definitely qualitative in craftsmanship. This should catch a lot of residual oil from the oil blow by in faulty Toyota engines. Done in 2 hours this time; I think I'm getting proficient with this procedure.
    Oil Catch Can @ 245k miles & Intake Manifold Cleaning | PriusChat
    Oil Catch Can Install @ 298k miles | PriusChat

    PARTS & TOOLS-
    - $24 amazon ordered OCC; has 2x 3/8" inlets; package came with extra fittings, inferior 3/8" braided tubing and set of laytex gloves
    - 6 inches of 3/4" braided vinyl hose
    - 5 feet of 3/8" fuel line
    - stainless steel reducer adapter 3/4" threaded end and barb side 3/8"
    - 3M Scotch Brite 1x stainless steel scrubbers
    - 4x 1/2"-1" hose clamps

    IDENTIFY SPACE- After clearing out the air intake/ducting system, I was able to access the 2x intake manifold ports w/o removal. This greatly reduced my procedure time in half. I identified a clear spot below along the center engine mount. I used 2x draw ties for OCC tie down.

    THROTTLE BODY- While i was down there i did some preventive maintenance on the throttle body. Opened it up and blotted clean ~3oz of blowby oil with blue towels. I am hoping this is what i will never see again, now that I have this OCC in place. I estimate its been ~5,000 miles since i last cleaned out the throttle body; so i guess oil accumulates fast... but nevermore.

    PREP OCC- i opened the OCC and placed a stainless steel scrubber. Theory is this and the bypass-oil fluids should keep low and stable under high pressure from the in/out takes lines.

    PCV VALVE PORT OUT- I swapped out the PCV valve for a new one and connected 3 feet of 3/8" fuel linefuel line. Tightened down with a 3/4" hose clamp to the OCC. I did all this blind, as my visibility was blocked by the intake manifold I chose not to remove, and leaving in intact.

    INTAKE MANIFOLD PORT LINE IN- This line required a reduction connector from 3/4" to 3/8". I threaded in the stainless steel fitting into the ~6 inches of 3/4" braided vinyl. The other end now fitted into the intake manifold port line in; hose clamped down. I then connected 3 feet of 3/8" fuel line and tightened it down with a 3/4" hose clamp to the OCC. Tie-downs for any loose flaring hoses.

    ROAD TEST- No CEL codes availed themselves at 70mph highway road test on cruse control for 10 minutes. No leaks, same engine noise, as if this procedure never occurred. More reporting in the months ahead...

    You gotta stop pulling the coolant hoses off the throttle body, lol.

    Have I pestered you about just cutting the OEM PCV hose at the middle, pushing 3/8" barb splicers on?

    ;) No kidding. I tell ya, each successive coolant line pull surprised me less. At times some coolant gets into the throttle body & mixes with the blowby oil. The first OCC i was shocked by the coolant flow rate coming out-- i lost ~2 cups of coolant; 2nd OCC I lost ~ 1x cup coolant; by the 3rd OCC I dropped only half a cup coolant.

    Now for blue-Prius this PCV U-hose was in much better shape than my white-Prius @ 300k miles. I could have probably repurposed them. However the new 3/8" fuel lines will bring new life to Prius, no matter how small an impact. :)

    Seriously, just leave those coolant lines attached. There's enough slack to get the throttle body out of the way, tied to something, and/or to maneuver it for cleaning. (y)

    perhaps next time w/ a bungee cord, for sure. I much more enjoy car projects that dont require removal of wiper-cowel.
    thanks.

    Hi all,
    I fitted a OCC today and after looking around the engine bay found a great position for it. I mounted it with screws 20200529_144006.jpg
    on the right hand chassis next to the coolant pump. It's low down and can't be seen when the air box is fitted.

    that looks like a nice out of the way spot, that will still give you access later for maintenance checks. Cheers.

    Does this help with the oil loss issue?

    My 2010 started consuming oil last year, and while it's not much, it annoys me. And it can't be good for the environment.

    +5mpg for posting

    Simply NO to your question.

    Our Toyota's have a faulty piston ring system. The OCC catches the oil that has blown-by, before it gets circulated into and affecting the combustion & exhaust system (PCV valve, throttle body, intake manifold, EGR system, O2 sensors, CAT, mufflers, etc). This could get sludgy and costly over time. The OCC helps us intervene and remove blown-by oil before it further spreads, sludges, and degrades other car components.

    Unless you replace these faulty rings, you will cont to lose oil. But in the near term, replacing oil is cheaper than replacing piston rings or buying a new engine. And for the longer term, having an OCC intervene and remove oil before it sludges, should save these essential car components and extend the life of your Prius.

    good luck

    NICE.
    - that short block option looks like an interesting alternative over a head rebuild
    - I wonder if many Prius owners took advantage of the 2016 TSB Repair Procedure Warrantee (<60k miles).

    I would think a short block and a head rebuild. The latter could be a relatively quick look-over by machine shop. The aforementioned gasket kit includes new valve seals IIRC. Plus pretty much everything rubber/plastic inside the engine.

    BTW, if you go to the short block price, what do you see for price (and presumably in USD)?

    What I see (in CDN funds):

    They seem to detect your location, automatically tailor price to your funds, ditto for shipping.

    With big and pricey items, they often don't show a shipping charge up front (they do with smaller items I've bought though). I sent them a message asking about this, and they said if you started a purchase process, it will not go through with the shipping charge still to be determined, and you do get a chance to back out if it's prohibitively expensive. Note also, at least so far with small items, they've charged nothing extra for duty and haven't imposed sales tax.

    Usually the rings start leaking after 60K? Just the way Toyota planned it... Anyway, some interesting info in that document.

    Wow, I overlooked that $
    That's a pretty hefty bill comparatively to the shy $1000 sticker price I paid for the white Prius
    with that money , I could buy 2x more Prius fixer-uppers
    (n)
    this may not be a value solution for me; for others perhaps yes.
