Catch can mod on Ecoboost still necessary on 2018 models

[st381183]

So my question is in relation to the video attached, I heard the Ecoboost engines in the 2018 models like the 2018 Expedition have direct AND multi port injection to keep the valves clean and eco reasons. So is this mod still a good idea? Should I consider doing this mod to my brand new 2018 Expy to avoid gunking up my valves from the get go?

Probably not necessary with port injection. If you want one, I’d save the cash and go passenger side jlt performance can. $140. 3rd gens have a dirty passenger side and I put one on my 2016. I’m very pleased as it’s collecting all the blow by (1/4 cup over 3500 miles) and my MAP sensor on the manifold is as clean and white as it was the day I installed the catch can and cleaned the MAP (which was gunked up and Brown)

That can in the video is $400 and you have to drill into your intake tubing. Jlt replaces one hose and attaches to the backside of the engine bay on firewall

Yes the new ones have port injection which helps clean the valves. Is a catch can necessary, no. It’s not necessary for any automobile. Are they advantageous absolutely because no matter what kind of fuel injection you got, every internal combustion engine is going to have blow by. It won’t coat the valves as quickly with port injection but it will still coat everything up stream of that. So while the the valves might be ok, the intake, intercooler etc is going to eventually get coated.

I would still get one because the blowby oil will still coat the inside of the manifold and intercooler with oil. It's cheap insurance.

Yeah I ordered the JLT plug and play kit for the passenger side. I think that will be the way to go for peace of mind.

Does catch can installation, void the powertrain or emission warranty? It could be considered a modification.

Yes. Keep some spare parts around in case you need to take it off before you go in for service.

@rjdelp7 no it does not. A jlt one is fine because you are just attaching it to a mounting screw on the rear of the engine bay and it uses the same types clips and hoses. A multi port dual side can like UPR WILL void warranty because that requires you drilling holes into your intake tubing. This is per Ford Technician Specialist I spoke to before installing my jlt.

Incorrect, plug and play will not void. Check your source from wherever you got that info
