Well, over the course of a 10,000-mile oil change interval (OCI) on our Gen 2 Odysseys, each of them will have consumed 20-ounces of oil. This is a combination of blow-by thorugh the PCV and oil that is combusted in the cylinders. That 1.5 ounces you caught in almost 5,000 miles of driving certainly sounds reasonable. As well, this is oil that did not enter the plenum, which is a good thing! :cool:

Thank you for doing this, documenting it, and reporting back. It's not ornamental...your catch can actually does the intended job, namely catch oil vapor running through the PCV system and keep it out of the intake tract.

Some of that is actually moisture blowby from the combustion process (it takes very, very little moisture to give it that "chocolate milk" look). That's normal, and this is a great follow-up, smufguy. I like that this stuff is removed via your catch can setup, rather than re-introduced into the engine induction system.

Given that the wife and I are now thinking of selling our 2002 & 2003 Odysseys and going for something newer, I'm now primed up to give this a try, too. I'm going to try and follow the same mantra you mentioned in your informative "Q&A" gig on Post #7 of this thread.

Thanks for the good pics.
 
I think a properly designed catch can is a good item to install on any vehicle. However, it does require occasional maintenance in the way of draining the captured oil and condensate. Since most manufacturers tout how little maintenance is required on any given vehicle, adding one more item to check (catch can), versus simply letting the engine devour the oil vapor and condensate is an "easy way out".

I'd want any vehicle I might purchase to be equipped with a PVC catch can, big ATF cooler with thermostats, power steering cooler, ATF fluid temperature readouts, and so on. That would put me into probably less than 1/1,000th of 1 percent of the buying public who actually cares about these things, which means manufacturers will never install them .... no benefit for the cost.

.... Here is a video of me dumping it out >> Catch Can Emptying.

Again, nothing much of a story to tell here, but you guys see what gets trapped.
That's a decent amount of blowby from combustion, and some water condensate that you prevented from running through your intake system.

Once I finish the remodel on my house and get some "garage man time" to myself, this needs to be my next project. The catch can you linked to seems to be good quality with the right guts and at a good price.
