For Those Who Don't Think a Catch Can is Needed on Gen 4 s...

For Those Who Don't Think a Catch Can is Needed...? YMMV...

I changed my 2020 FX4 engine oil at 1K and added a catch-can.

The below is what it looks like/how much from the catch-can after 7K miles (2K towing a small 2,000 pound trailer). That is a standard size shot glass--and it stank like heck of raw gasoline.

I wholeheartedly agree they need them.

But some clarity, design wise they don’t produce less than the previous, it is just that the 4th Gen have the 2nd Gen 3.5TT, that has Port in addition to Direct Injection. The Port injectors in addition to providing more fuel at high load demand, they have the secondary result of washing the intake valves and decreasing buildup that sits on them.

Yes, best thing to do is prevent it from getting there in the first place with a catch can.

Which one did you install? I still haven’t picked one up as I don’t drive much and it just slips my mind.

JLT is easy, and won’t break the bank!

First week I owned my 4th gen expy I installed a JLT catch can. I'm affirm believer that if you take care of your ride early on it will still be taking you places 10-15+ years later!

I would like to see a 5K mile oil analyst without the catch can and then one with the catch can after another 5K.

@Fozzy you volunteering your baby (expy) for this? I’d like to see the results though...

TTBOMK, the catch can has nothing to do with the oil inside your engine, since it ingests the oil caught above back into the intake valves & combustion chamber, reducing octane and causing carbon buildup, etc. Previous 3.5s had it worse, but the new gens have fixed the carbon buildup by injecting gas before the port cleaning the valve.

Either way, not good to ingest, regardless.

this is all oil blow by caught in the PCV system. They are a must if you want a healthy engine. Also cleaning MAP sensor bc that gets blow by all over it too

not worried. Cyber truck coming soon.
I will pass the headache to someone else.

@Fozzy

About to put some miles on the truck. Any analysis company you suggest?

 

[Fozzy]

I always use Blackstone labs when I was a diesel dick . It’s like $30.00. I have always been curious if these make any difference in the fuel pushed into the oil. At the OP’s current rate you would have to drive over 500K miles to get a gallon of crap stuck in your CAC. Which one are you going with?

JLT seems to be the one everyone is suggesting... As humid as it is here I have a feeling I'll be getting more "deposit" than others. If I only have 2-3k on this oil change is it still worth getting the analysis? Or should I wait and do it after the road trip and get the can installed when I get back?

Didn't realize you were a body builder?

Actually Foz, that is just shy of an ounce, but if we give it an even ounce at least 896,000 miles for a gallon

And FWIW, my driving style is leisurely, with only occasional full throttle bursts to let things stretch a bit. 99% of the time I drive in Eco-Mode.

I have seen people drain a bunch of crap out of their CAC that doesn’t look good. But we have Ecoboosts at work with 200K miles that have had nothing other than 5K oil changes. With nothing wrong with them. Not even cam phasers. A few other problems. I will probably dump mine in a few years or next model refresh. So not sure it’s worth it for me but if it helped keep the oil cleaner I would probably go for it.

Yes I was a body builder, turned power lifter. A few years ago I had a major quad tear and last year a hernia. Been out of the gym and off the “supplements” for almost a year now. Still have a lot of size, but the conditioning is gone. Need to go back but the CV bothers me a little.

So I own a 2007 Expedition Limited and I put the JLT catch can on it. Haven't emptied it yet because I just put it on. I am fixing to do a oil change soon. So I'll post a pic after. I am in the process of start a youtube channel which will start with me working on the Expedition. It was mistreated and I want to bring it back to it's former glory.

A CC reduces carbon in the intake track/valves.

It has maybe less to do with engine longevity to 200K, but power, efficiency, etc. on the way there. It may be the smallest thing you can do for your engine's health, and far less important than correctly timed oil changes. But I already address that with an oil change at 1K, and the latest at 8K to fully synthetic 5W30 with 28% oil life left.
YMMV.
