Oil Catch Can, Eliminate that knock!

Should clarify: I've heard airline style clamps are not good with plastic spigots, coolant spigots for example. They tend to put point load on the spigot just at the tightening screw, can crack plastic spigots.

 

Yeah, understand. Funny: Toyota uses no clamps on a couple of coolant connections. Cribbed from your pic, one here:

 

I like the mason jar mounting location the best. I don't want condensate building up in the lines anymore than necessary.

 

Just for reference, PCV valve info from Toyota Repair Manual:

 

I ordered one, and maybe we'll install it at our next Bay Area Prius Meetup

 

I wonder: would there be room to put the can quite close, say just remove the orig U-shape hose, plumb in the catch can as close as possible? I have the engine enderpanel off every 6 months for oil change: maybe some spot close but accessible from below:

 

Is the G3 pcv located that low on the car in your diagram? Because on the g2 its located on the top of the valve cover.

 

Since you'll be removing the intake manifold to make this setup, does that mean the egr cooler is back on?

 

i have/had a few toyotas and all them (except the 3rd gen prius) have the PCV on top of valve cover with an elaborate air/oil separator below.
i have no idea why the prius PCV is so low, makes it very hard to check/replace. are we positively sure there is no air/oil separator behind the PCV in 3rd gen prius?
danlatu, you looked inside the block, right? does the pcv hole open directly into the crankcase?
how about the 4th gen?

 

Yeah, let's try the whole enchilada! Are you up for it?

 

Jacek, what we do know is that oil pools inside the throttle body, and it has to get there somehow.

I replaced my PCV very recently, and it didn't seem to be oily. I didn't inspect the PCV hoses for oil, but the PCV valve itself was dry. Do you agree that when I remove the PCV hose to install the oil catcher, the hoses should be oily if this is indeed the problem?

The other test is that I will remove and clean my intake manifold and throttle body, and we can inspect the throttle body after 5 or 10K miles to see if oil has returned. If the oil is gone and stays gone, then I'd assume the catch can works.

 

I'm down, but it might be better to do in Fremont as your block will be cool and you might be able to do a little pre-work( remove the windshield wiper cowling, engine coolant, etc).

If you still want to do Lafayette, you might have to be first up so we can get that work going first as it adds a couple of steps and time to the job.

But count me in.

 

Let's make it Fremont once more, and Lafayette next time. I'll order up some pizzas and have cold drinks for everyone.

 

Wonder how much is coming from the valve cover vent? Maybe tee the PCV and valve cover vent to the OCC then outlet to the IM.
