Aftermarket catch cans use the PCV / vacuum derived from the stock system to "catch" blow-by (or the vapor remnants) that the stock system simply does not do. The excess oil build up that would come from said blow-by in the intake manifold can foul plugs and even, eventually, interfere with combustion.
The short answer is no, you wouldn't be throwing your extended warranty away. Although, depending on how you deep you plan to go with modifications, it starts to depend on your dealer's service writer. Some dealers are more mod-friendly than others.
With the single valve catch can, may it be removed if needed without any indication it was once installed? Appears only the dual valve requires a small modificaton and if in doubt that mod could be removed by purchasing a second OEM turbo inlet tube/hose.
Yes, that is correct. Single valve catch can requires no modification to the factory tubing or anything that cannot be simply put back to OEM, therefore making it untraceable. In theory, it could take less than a minute to remove it if you know what you're doing.
I hear you. Thanks for the input. I had issues with my last Ecoboost where I did some similar mods like I have already started with the Braptor. Right before I traded it in for this thing I was starting to get some mis-fires and I also noticed I had some oil getting into my intercooler. I definitely do think that over extended periods of time these catch cans can really save some engine problems from happening. Especially if you are running it modified. In order to stop oil from getting to unwanted places would it be better to have the single or dual valve? I really like the simplicity of removal of the single to cover my rear if I needed to bring it for something engine related, but would it trap enough to help over time? I guess basically what I am asking is does the single valve trap more unwanted oil than a dual or is the same amount of unwanted oil coming from both places?
Yes, the Single Valve will get the majority of that unwanted oil mist out of the PCV system (roughly 80% of total PCV system) and will definitely will provide a long term benefit to not having one at all. The dual valve essentially adds a source of vacuum that stays vacuum under boost, just allowing for the catch can to work under both boost and regular driving. If you drive the truck flat out in full boost everywhere you go, you may want to opt for the extra steps the dual catch can calls for, BUT, if you drive with lots of cruising and occasional pulls (like the majority people do), the single will do just fine.
Perfect. That is what I was wanting to know. Thanks for the info. I’ll be getting a single on the way soon it appears then. Typically too much traffic where I am at to drive like an animal everywhere. Ha. Sure would be fun though.
Is the catch can a real fix or just an expensive band-aid? I wonder why Ford is not advocating it?
My dealer won't have a problem with it, however I went with the UPR single valve catch can above as it can easily be completely removed without a trace it was ever installed.
My Raptor is in winter storage, I'd love to drive it in the snow but we have very salty wet roads all winter. Been detailing and modifying so it's ready once the salt washes away.
