Default How is this catch can looking?

It was half way full at about 1000 miles. When I began emptying it was just like oil. Then towards the bottom of the can was a white thicker substance. Normal? I change oil every 5,000 miles with Mobil1. 2016 3.5L eco with 24,300 miles.

Oh boy lol. For me, it's cheap insurance. I bought that can used for $50 and I'll likely recoup that money when I go to sell. It's really out of site out of mind til it's time to empty it.

​​​​​Anyways back to the topic at hand that thicker white stuff OK?

Looks magnificent!


Insurance from what exactly? Not trying to get a debate started -just curious what's on your mind.
And how does a catch can increase vehicle value?

​​​​​​Insurance from that stuff going back into the intake. It may help, it may not, I really don't care. I'd rather empty that oil out every thousand miles or so. Either way, it will end up in a debate.

I never said it would increase vehicle value. If I ever go to sell the truck I'll simply take it off, put the original hose back on and sell it.

So in the end the catch can is really going to cost me nothing to run, and like I said ease of mind and cheap insurance.

I thought that "extra" stuff picked up by the catch can was beneficial for top-end lubrication. Is it possible that removing it is hurting?

The root cause of the oil movement is..the Rings have not seated and the use of full synthetic oil is retarding ring seal breakin, on top of it.
The only reason there is so much pressure in the crank case to move that much oil is rings are letting to much combustion blow by the rings.
Stop using that oil and let the Rings seat.
Use the blend 5w20 oil specified.
The PCV system is the only place that pressure can escape and is also being pulled by the intake airflow.
.
My 5L took to 58,000 miles to stop passing oil on 5w20. No TSB, no mods or band aid fixes of any kind have been applied.
Nothing happens by magic, there is always a reason >>that has yet, to be addressed by you know who!.

It looks like every catch can. Unnecessary.

Synthetic oil does not inhibit ring seating.

Yep, it's all just magic!
Add turbo pressure and it a bigger magic.

@Shadow2016Black Getting back on topic, the peanut butter like substance is quite normal from what I've seen. It's just an mixture of oil residue and moisture due to the contents being hot when it enters and cooling down inside the catch can. I have an FR can on my 5.0 and see similar (the one on our Focus ST doesnt seem to show as much, but could be due to where it is placed right next to the engine/transmission). My prior '13 Tacoma used to develop a little of that on the underside of the oil cap if i didnt drive highways often enough to get the oil all up to the proper temps.

I too like it for just a little piece of mind knowing that oil isnt being recirculated and burned in the intake side of things. Everyone has their opinion on benefits, so I wont say one way is inherently better than another just my preference (like I think you have regarding the use). Though I will say for only 1000 miles that does seem like a bit of oil. Cant quite see how big the can is, but at least from my experience I've never seen more than 2-3 ounces in any of mine between my 5k oil changes.
