What's with the oil catch cans?

[HSKR R/T]

That should show up as running rich on the O2 sensors, which should then cause the ECU to lean out the AFR...assuming our trucks monitor AFR. I can't find anything definitive on what flavor of magic is in the tuning.

Ever watch your LTFT numbers? Run a higher octane fuel and the PCM pulls more fuel than a lower octane.

I haven't on this truck. I know my Ford would adjust long term and short term depending on what the wideband o2's reported.

Variable cam timing is used in place of EGR.

Ah, I see that now. Very cool.

At my last oil change I was down from 5oz to 2.5oz of condensate in the catch can. 33,xxx mi.


Also, here is a picture of the back of the exhaust valve when I installed my shorty headers. I know it's not the intake valve, but you can see how clean it is burning.

That looks to be about how much I get out of mine, maybe a little less. And has never looked like a milkshake, unlike some guys that I have seen on here.

How easy was your shorty install? Been considering it, fortunately no rush as I haven't had a lot of free time

This is is 2400 miles worth. I though it would be more milky. The water on the bottom of leftover from my rinsing the bottle.

The milky stuff is a winter phenomenon

Is the milky mix caused by condensation occurring in the catch can which then mixes with the oil (in the catch can)?

 

[Scram1500]

I'm not sure what causes the winter emulsion, seems to be worse with short trips. Must be related to extra condensation from the cold

Yeah, I'm just trying to understand if the "winter emulsion" is actually coming out of the PCV valve or if it is mainly oil coming out of the PCV valve and the "winter emulsion" is forming inside the catch can. Just curious.

joined the mishimoto extra maintenance club today

it was really easy to put on and the design is fantastic, i only have ~7800 miles on my truck so we'll see how it goes!

That's not condensate.

That's not condensate.

Well, don't be so sure. It is definitely not pure oil. There is clearly a good bit of water, maybe mostly water, in these catch cans. It looks much more like coffee than motor oil when you see it in person.

And smells of fuel

 

[Nails]

The winter times will bring that stuff to the CC.

 

[Ramjack]

LOL, I guess I should have said Starbucks coffee.

Anyway, I don't think mine smells of fuel. I'll have to check in the morning to be sure.

 

[mtbiker033]

And smells of fuel

totally agree, thinner than oil, smells like gas!

Interesting. I just checked mine and it does not smell like fuel.

Anyone know what size tubing they used to connect to and from the can?
I have some 1/2 inch tubing but I think it's too small for the fittings.
