Yeah, yeah, we totally said we weren’t going to do much to our 2010 Toyota Tundra, perfection already having been delivered from the Toyota factory in San Antonio, Texas. But that doesn’t preclude us from making our experience even more exemplary.
Our first modification was an easy reliability addition in the form of an air/oil separator from Moroso. Of …
So what do you do with the oil?
IDK we all used to just go to Home Depot and buy a $20 air compressor air/water separator (the large one, not the little tiny one), which works exactly the same as the Moroso one but does it at 10% the cost. Routed in-line with barb fittings and back to PCV. I had one in my car for years. Had to empty the oil out every 6 months or so. Just gotta make sure you get the glass/metal one (the plastic ones don't hold up well if they're mounted in a hot area)
I mean, not as blingy as the Moroso one, but then again, nobody's ever gonna ask you to see your Tundra engine bay lol. So, just in case you wanted something a bit more.....uh....grassroots ;)

same thing you do with the old brake fluid you bleed out of your system. you (don't just pour it onto some paper towels in your trash can) recycle it appropriately. Or I suppose you could just pour it back into the oil filler, really.

Same thing you do with the rest of your used oil I suppose. I won't judge.

Yeah the process is certainly similar, but there's something to be said for a one-box solution with zero fabrication aside from cutting hoses to length required. Nice having options at both ends of the spectrum.

Let's try this again. Does it accumulate in a container that must be removed and emptied? How often?
In reply to spitfirebill :
Depends on the amount it accumulates, but generally you empty them at your oil change interval. It's not usually more than a few ounces if everything is working correctly.
The only time I've ever seen more than that in my MS3 (which is notorious for oil making its way through the PCV) is when I broke the turbos journal shaft and filled the can.
JG Pasterjak said:I won't judge.
Do yourself a solid and replace the PCV valve. They are cheap and typically the cause of any oil consumption on the 5.7.
If your 5.7 is using oil or filling a catch can, even under heavy towing, its broken!

On a street driven vehicle like the Tundra—even with towing—you'll probably never fill it up unless something has gone horribly wrong. I'd empty it with each oil change and expect a teaspoon or two of oil to come out. Any more than that should send you looking for other issues.
On the Corvette, even with a 100,000 mile motor that only got run hard on track, I'm empty it after every couple events and it was maybe a few ounces. Maybe a bit more if I was at a track with lots of long left handers.
This is a neat and straightforward mod. Thanks for the writeup! Will look into doing this on my Tundra. Moroso makes some really nice pieces. I've got their aluminum expansion tank in my E46 M3.
I should do this to my jeep xj, has a bit of blow by on long driving days.
These are really popular in the EcoBoost community. Some people get a LOT of oil out of them, some get none. I havent decided if I want to put one on mine or not.
In reply to JG Pasterjak :
Now that is funny
I installed one using a harbor freight air compressor oil separator.... other comment reminds me of working a construction job in 1981. We just finished an apartment complex. First new tenant moves in, pulls his 60s Biscayne over top of the parking lot storm drain and drains the engine oil into the drain. Right through the trees is the Chesapeake Bay. Real classy! It was southern Maryland.
In reply to ultraclyde (Forum Supporter) :
Yep. I added one to my 2018 F150 2.7 Ecoboost. It was a very easy install.
So far I've only seen a very small amount of oil collected but of course I don't drive much since I work at home.
In reply to JG Pasterjak :
Hardly enough to go to all that trouble.
