I have a 2018 f150 eco boost . I was thinking about putting a catch can in
Does anyone else have one and are they a good idea ?

 

That topic brings a lot of opinions. Cliff notes for other such related threads are likely to contain the following:

- People like them and dislike them
- They are good and bad.
- They can be beneficial and harmful.
- They are worth it and a waste of money.

That being said, I like mine both in my F-150 and Focus ST.

 

have you ever had any problems?

 

Only a structural issue on a Mishimoto bracket for the one on our Focus ST. It is autocrossed and driven fairly hard at times so I think the engine movement or vibration caused some fatigue.

Other than that, no issues. I am fortunate enough not to have too much accumulation that emptying it during oil changes at my 5k interval is perfect as for me that's at most 1/2 full (2-3oz perhaps) at that point.

 

-They catch stuff
-they don’t cost a lot
-dont do any harm unless you forget to empty


-people think they only catch stuff because the extra hose and temp difference causes condensation despite some actually getting the content tested and it’s not just water

-there’s a new, small group of people on this forum that think by removing the liquid you are causing harm due to eliminating cleaning agents and oil from the intake…weird the anti guys that think removing the liquid harms the engine never disagree with the anti crowd that thinks it’s only dirty water

-the anti crowd are super sensitive to the topic and will not rest

-you’ll also hear that it’s good for high performance vehicles but not good for a 400+ hp/tq twin turbo truck pulling a 12,000 pound trailer

-some will say if it was needed ford would’ve added it, this is my favorite as it implies a lot of other things that are either ridiculous or far fetched.


personal opinion: i had one on my 2017 3.5 and 2018 2.7 and it caught a decent amount in all seasons, had one on my 2019 3.5 and it never caught an ounce 🤷🏼‍♂️

​​​​​​​currently don’t have one installed

 

yes and yes. My mechanic also recommended the catch can. Easy install. Go for the higher capacity can.

 

Have 200k+ on my 2011 3.5l. IMO This isn’t an engine that benefits from a catch can. No oil consumption. Original timing chain. Runs and tows like new.

I’ve had the intake off to replace jiffy fittings behind the heads. So have seen carbon buildup on intake valves, there is not much. Valve coking problems with the 2.7 and 3.5 is just another urban myth.


If your engine is an oil burner it may well benefit from a catch can. It is your engine. Put a can on it if you want.

 

Have had no issues with mine. Empty it out from time to time. It accumulates very little.

 

No vendor would ever sell anything that didn't work? Would they?

What is the harm in letting a little oil and water pass to the combustion chamber? On DI engines water and oil are exactly what one wants to clean the back side of intake valves.

The crankcase ventilation system is rather complex on our trucks. Don't mess with it. Aftermarket companies do not know more than Ford. If a catch can saved anything on warranty costs, there would be one on each side of the engine.

 

Remove the inlet duct from the throttle body and stick your finger in the duct. If it comes out dripping with oil, you may need an air/oil separator. If not, put the duct back on and forget about it.
