Hello Ford folks--

I know this probably isn't the specific forum on which to post my query, but I am counting on your knowledge and experience to help me with a question. I'm considering a 2018 Lincoln MKX with the 2.7 ecoboost engine. My question is: Should I have a catchcan installed from the get-go? Or is this a moot point that engineering has resolved?

Many thanks for your responses.
Dave

 

You should lease it and not worry about such things!

But if you insist on actually buying a Lincoln, no harm can come from a catch can mechanically so long as you're draining it. Technically it's in violation of EPA since it does tamper with the emissions system. You do hear stories on some sludging of the EB motors, but at the same time, most are going to high mile territory without ever showing signs of any issues. From what I've seen in my own online research, I don't know that enough oil is generally caught to be worth while IMO. With oil changes between 7500 and 10000, over 200k at most you're looking at 26 oil changes, and based on the pictures folks show of how much you capture between a change... that adds up to what, a quart? Assuming a majority of that does what it's intended to do and burns, you really aren't left with much oil to cause sludging, so I believe most of the problems are caused by PVC malfunction, not engineered use. So while I believe a catch can does improve the life of the motor, I do not believe it is the bottleneck of life expectancy, so I do not believe it to be a genuine improvement to normal use. That's all pure opinion and speculation and I'll be looking forward to reading alternative reasoning. I like the principle of the catch can and would love to find reason for it to be a gain.

 

Thanks for that concise response. I've had friends with the 3.5 ecoboost that have had problems, but I'm betting they are isolated incidents specific to early models. Thanks again. Your comments make sense!

 

I've been watching the catch can "scene" for a year or so and it seems like those on YouTube and the forums with the most benefit (crap caught in the can) are running tunes. I've yet to find anyone using a CC with a stock tune show a benefit that outweighs their cost and risk .

 

Also be advised the install may interfere with the drive-train warranty. It would be up to the dealer and FORD rep if any engine problems occur.

I believe in them myself.

 

Just keep your oem hoses from the PCV' . Catch cans catch a lot on my 5.0, burning oil is not good for anything especally going through you air intake.

 

Please post pics and your results when you have time. It's always good to hear how those things are working for members.

While this is an extreme demonstration, it will give you an idea of it's function.

 

I don't have an EB motor, but run air/oil separators on both of my Shelby's. I only run one on the passenger side. ( PCV )
NONE of them catch all of the oil mist, but they reduce the amount of oil getting into my intercooler. ( mounted below the blower )
I have seen pics of motors not running one, not pretty. There are those that say your gas's octane can be reduced by too much oil mist.
Mostly it's on boosted motors, but owners of NA 5.0 Mustangs seem to get lots of oil in their catch cans.

NICE RIDES!

I don`t think the drivetrain warranty would be an issue with such an item considering that Ford Racing Performance Parts also offers their own branded catch can.

 

These are my 2 JLT catch cans on the firewall. Together they catch 3 ounces of oil every 3000 miles ... my intake valves must be so much cleaner , Thanks JLT !!!!

 

Nice and thanks for the info on how these have worked for you because i`ve been considering two of these for my 2016 Lariat 5.0.

 

Now is it a can or seperator plate you are looking at?

If you notice carefully, FPP states that it for OFF-ROAD USE only.

The only was it would be emissions legal is to have a C.A.R.B exemption.

If FORD is called on an engine warranty claim, they are going to use any excuse they can find not to honor it. All you have to do is follow any ESCAPE bulletin board.

Not saying they will or won't but you have to cover your a$$.

 

I haven`t seen any but I don`t believe any catch can/oil separator on the market would be considered emissions legal or are C.A.R.B exempt therefore all of them are OFF-ROAD USE only.

I`d like to hear from F150 owners who have one or two of these items installed and the dealer voided their engine warranty.

It`s not a new camshaft , it`s strictly air and vapor related and is really no different than putting in a new exhaust system or an aftermarket air filter.
