Oil Catch Can. Yes or No?

[Racket]

After being involved in discussions about the intercooler system and considering upgrades I would add that a catch can keeps oil/moisture out of the charge pipes where it has been an issue in similar vehicles and I presume the long term performance of the intercooler itself.

True, the return line is the pvc inlet
Catch can cleans that vapor

Every time I empty mine I imagine that stuff DIDN'T get to the intake so I feel validated.

1. Egr deposits are very minimal on a gasoline engine. So yes, the primary source is from pcv.

2. Yes they have. The problem is the pcv, the oil that makes it through cooks onto the valves.
Edit: Whoops I think I read it wrong

Not sure saying it makes it so..., especially when "Quantify" is described as as minimal.
Fact is PCV is minimal as well.
Don't forget that EGR includes valve overlap on every exhaust stroke.

I still haven't taken sides on the catchcan question, but i would insist on something other than doctrine and anecdotal evidence.

Can you say definitively that adding a catchcan and servicing it properly will prevent intake valve deposits?
There are lots of Ecoboost engines with over 200,000 miles with no catchcan.
So how do we quantify the problem so that it is possible to determine the need, let alone the effectiveness?

You seem to be misreading what Ive posted. I suggest you do your own research.
The research has been done and the data is there. You won't find it on a forum.

Have been and so far have found very little indisputable evidence to support this mod.
Lots of anecdotal evidence and empirical evidence without good science behind it.
Sure there is enough to convince a lot of smart people that it works, and some more who think "it can't hurt" so I might as well.
Many who think the problem is real, don't believe that a catchcan can actually solve it.
Commonly the best "hope" is to delay the inevitable.
If a Ranger needs a valve job at 100000miles with no catchcan (unlikely) then it will be said
"it could have been put off another twenty if only you had used a catchcan".
That might even be true...
Stay with the Forum and lets compare at 10 years or 100000miles!


One other point,
Eighty percent of Ranger buyers will have moved on long before the problem presents itself, and aftermarket mods seldom return their cost to the seller, many even reduce value.

100% agree. Exactly what I brought in the end of my post in post #372.

Maybe I was the one misreading posts

Very well put sir.

Just say no to catch cans....

Just say no to catch cans....

Considering what mine are catching... not a chance in hell.

As someone mentioned the ecoboost engines have been around for some time. Any Ford mechanics on the forum that has seen the valves on these engines in other models know what they look like after significant mileage. What does the back of the valve in the Focus RS looks like after 40-100K would be interesting to know, considering, the Ranger has a very similar set-up.

Does Ford have a service bulletin or scheduled maintain for valve intake blasting/cleaning on the 2.3L ecoboost?

I suspect most of what is in the can is water condensation with trace amounts of oil. The high location of the cans in the engine bay may be the reason for most of the liquid/condensation. Some can live with trace amounts getting into the intake other can't, each to their own as it is their vehicle.

Personally, I have no interest in one on the truck as it has a baffled plate exiting the block and does not see high RPMs, however, I did run a can on a built Honda B-series engine that lived most of its time in high RPMs on the street and track.

It’s definitely not water. I know what oil looks like. Been driving and taking care of my vehicles for 51 years.

I put a catch can on my tailgate damper. So far so good...

Catch can is 100% worth it. You sound like you’re trying to justify being cheap over a mod you can do for cheap.

when I empty my catch can and pour out a tablespoon of oil that would have made its way into my intake how isn’t that worth it? Why don’t you take off your intercooler, pour a little gas in it, swish it around and watch what color it is when you dump it out...
