2010 Prius 100,000 Mile Preventative maintenance Items

That is surprisingly clean, that car should service you well!

SAE30R7 is a buck or two per foot, should be available at any local automotive speciality store. Hose barb splice (aka mender) should also be readily available, or PEX connectors, which are easier if you ever want to disassemble. Ditto for hose clamps, but the latter are not really needed with hose barb connectors, might even be detrimental to hose end.

 

While an OCC may reduce the oil reaching the intake, it does not address the source of the oil. A faulty PCV valve can cause oil loss in addition to stuck piston rings.

Since you take so much effort to address this problem, you may also consider to move your PCV valve to some place it can be easily accessed along the input line of your OCC. This will make the future PCV valve change much easier.

 

Ditto. Would that also allow you to effectively raise the pcv valve thereby reducing the amount that comes out of it?

 

@Rocky Mountain Priusman & @AW82 Yes, it may achieve two goals: Easy access and less oil emitting. Check the link below:

 

Awesome. Is that your video? I actually ordered the same catch can and it arrived today. I opened it before I watched your video and thought "hey, these fittings might screw into the PVC hole in the engine..."

Question: I also got a new PCV valve. Is it supposed to be really rattley?

 

@Rocky Mountain Priusman & @AW82 No, that's not my video. My 2012 Prius has 112K miles on it but not burns any oil, and I am debating whether I need to modify the PCV line in a better way. That's how I found that Youtube.

Not sure if you can skip the welding fitting, and fit the 5/8" hose directly on the thread side of the PCV valve. Maybe teflon tapes will be strong enough to prevent leaking?

I believe "rattley" is what a working PCV valve should be.

 

Probably not the correct size, but I wonder if something like this would work.

 

Is it the Toyota part, or aftermarket?

 

how effective do you feel that the catch can will alleviate the pooling?

 

If I may jump in, maybe 80%. Also, I suspect the pooling is only a portion of the PCV feed: some passes right through as mist how much hard to say?

 

Supposedly. It's this one and is marked Aisin.

(Edit: it's from Amazon..pasting an amazon link here turns it into an advertisement which my browsers blocks, so I'm not sure if everyone else will be able to see it)

 

I think the PCV valve is type G, 16 x 1.5 mm, not NPT, so they don't fit. But experts please comment.

 

Is this a comparison without PCV valve change/cleaning? Or is the PCV valve effect included?

 

@Mendel Leisk How important is it to have an OEM part? I ordered the following aftermarket part on Amazon:

 

I just cleaned my 2002 Odyssey EGR passage. There are also oil puddles under the intake plenum cover. So this looks like a popular phenomenon for many cars:
