I just replaced my stock intercooler for a FMIC and at 40k there was barely anything in there, it wasn’t even enough to drip on the drive way. My truck in California definitely does NOT need one. Argue all you want but they a unnecessary or Ford WOULD have one in there. The chocolate milk shit you got there is probably because of the catch an not the other way around. Anyone of you actually take your intercooler off and see the accumulation or are you guys just thinking it would be better?
Snake oil I say.....

Sure, the can magically makes this concoction all by itself! LOL!

As others have stated due to the maintenance is the sole reason why manufacturers don't have one from the factory.

There are others that have stated that there was oil in their IC when replaced so.....

That's because only the CCV draws suction from the drivers side turbo. The PCV draws suction straight from the intake manifold. The amount of gunk generation can be directly related to how hard you run the engine. If you are constantly running around with boost pressure pegged out you are going to generate a lot of blow by. Most people on here probably don't drive their vehicles like that.

Look at any high performance track vehicle that is FI and they will have either a catch can setup or a dry sump oil system that will suck that stuff out. If you just baby your truck around than sure, you're not going to see much of that stuff. Beat the crap out of your truck you're going to generate a lot. You got a high performance engine so what's a little extra to make sure it continues to run nicely? Hell the average rate for a triple fog set up is 1k for lights you might use a couple times a month so what's $150 for at a bare minimum JLT catch can that actually removes crap from the engine?

I swear this is the only place where I've seen so much debate over running a catch can. Look at any other factory turbo vehicle forums and it's like spoken word that your 1st mod had better be a catch can or an Air Oil Separator.

*shrug* Like others have said to each their own. Just my .02 cents.

have the same choco milk shake but lots of nasty sticky sediment at the bottom of the can. usually fill up the whole jlt can (small as heck) after 5k mi. (the jlt extensions will not fit on a raptor btw with the intake blocking the way..dont ask)

Not enough miles on the newer EBs to tell and I wouldnt rely on "since Ford didn't put it in, it was unnecessary" as a viable argument.


Watched the video a bit then decided it couldnt hurt for a catch can especially since I run 87...will switch to 93 when I move in a few weeks and am finally near a costco. (at 22k mileage so I hope it isnt too bad)

Maybe it’s not necessary, but neither are 5000 mile oil changes, according to Ford.

Do what you feel is best, personally I have one.

They aren’t installed on production vehicles because the manufacturer doesn’t want to put additional maintenance tasks on the consumer.
hi
what catch can are you using ?

I think you need to look at it from the perspective of designing a car to be used, day by day, by the average idiot. You're talking about installing a small can that can accumulate oil and, eventually, fill up and cause problems. As an engineer designing something for the general public, it's easier to just plumb it back into the manifold, let the engine deal with it, and the customer never knows the difference. Lots of decisions are made on the car from this point of view. They're selective "compromises" that everyone knows aren't necessarily "ideal" from a performance point of view BUT, taken on the whole, and when considering customer behavior when weighed against the average length of ownership, make sense. Not having a catch can on a forced induction, direct injection engine is one of these compromises.

You're absolutely correct, the harder I ran my truck the more I saw in the catch can.

like the old m4 direct impingement vs gas piston arguments...oh how I despise cleaning off my bolt carrier grps and especially revolver cylinders. :banghead:
Sure the port injection likely keeps it very clean, but the catch can likely augments or assists.

would a majority of the blowby make it back to be burned in the engine prior to before it hits the intercooler?

not a rappy but helps somewhat if you are on the fence:

Our engines have 2 suctions. 1) is the PCV system where I'd say 90% of the crap generated is from and 2) the CCV.

The PCV draws suction directly from the intake manifold so the rest of the intake system doesn't see it. I just dumps straight back into the intake manifold.
The CCV draws suction from the drivers side turbo. So that turbo and all the piping down stream from there will see it.

If you drive your truck pretty hard you can start to build up oil stuff from the CCV in the intake system. Easy place to spot it is the drivers side turbo outlet at the inter cooler connection point. This stuff can start to coat your sensors after a while. It's not a ton but at a bare minimum you should keep up with cleaning your sensors. I just replaced my IC at 8500 miles and I did have some oil pooled up in that silicone coupler since I only run a PCV catch can. I didn't realize at the time when I got mine that the 2 systems were separate.

Here's a break down of the catch can styles for our trucks.

No Valve (JLT). Collects only PCV blow by while "off" boost. When in boost the intake manifold is pressurized and therefore the engine does not draw a suction on the PCV system. This is how the truck is stock.

Check Valve (UPR). Collects PCV blow by while on and off of boost. Comes with an extra line with a check valve that draws suction from the turbo inlet so that the catch can collects while on boost.

Dual Can (Radium). Collects PCV and CCV blow by both on and off boost. Kit comes with 2 separate catch cans. The PCV side has a an extra line with a check valve like the UPR. The CCV does not require this since it already draws suction from the drivers side turbo and therefore will always be under vacuum.
