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.

 

[st381183]

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

The dealer can void your warranty for whatever reason they want. Will it void it? It shouldn’t. But if you have a complete motor failure you bet Ford will use it against you if they want

Oh yeah, and it’s probably different for every dealer too. Most times they can’t deny a warranty claim unless there is hard evidence that a mod caused the malfunction. But like you said, they can do what they want. Luckily, my dealer was impressed with the steps ive taken to keep mine clean and said it won’t be an issue

They can plug in a laptop and look at detailed engineering data. I don't see any problems with normal powertrain warranty issues, with any manufacture. The catch can however, taps into the emission system. That is covered under a separate warranty. Say, you pull into dealer with a "check engine". I can see some service advisor, saying "its not covered, because you messed with it."

So JLT for the passenger side, what about for the drivers side?

Driver side is the clean side. Check your MAP sensors. I’ll bet the ones on the intake tubing and throttle body are both white. One on Intake manifold will be black and gunked up and covered in oil. I cleaned the one on the intake the day I put the jlt passenger side can in and it’s as clean as it was that day now after almost 5000 miles. Would a driver side can hurt? No but it’s not as necessary as a passenger side can. I have no visible oil build up anywhere in intake tubing. And from my research, the passenger side is known to be the problem child with oil blow by into the intake manifold and all over the valves. My results have shown the can is doing its job

 

[st381183]

Thanks. I wasn’t sure and as I looked there appears to be a sensor on the drivers side hose that doesn’t appear, as far as I can tell, on the hoses from 2017 and earlier Ecoboost motors. I’ll stick to passenger side.

FYI - the JLT Performance passenger side oil catch can for 2018 F150 will not fit the 2018 Expy. I know because I tried. The Expedition has electronics mounted where the F150 doesn’t and the Expy has a much thicker engine cover so the can has no where to be effectively mounted where the reservoir can be removed for emptying. I was very happy with the quality and customer service. JLT did advise that they would be work8ng on a 2018 Expedition catch can system plug and play but needed to get their hands on one to test fit hoses and figure out where to attach the can. Just thought I’d let anyone interested in doing this know that the F150 can does not translate to the Expy. I sent it back and hopefully won’t have to wait too long for a JLT can.

 

[J Ski]

They have requests out at their shop for 2018 Ex’s test vehicles. No ones been up there yet that I have seen or heard of, I live 15 minutes from them

 

[edizzle]

where are they at?

I remember reading once the ford dealer denied a guys warranty claim on a blown motor and blamed his aftermarket rims and larger tires, they can deny anything. They claimed the odometer was slightly incorrect due to the alterations and could not verify mileage so they would not cover the motor.
