Oil catch can

[Kilo11]

I was watching a you tube video about oil? Do I really need a catch can????????

Some will say no and some will say yes. Ultimately up to you and if you want to spend a few bucks on it. There are a few that are popular....UPR, JLT, and Mishimoto just came out with 1. Personally I got 1 (UPR) and am happy with it. Just drained it after 6000 miles
if you can pay 65k+plus on the truck, a few hundred isn't gonna kill ya. I'd rather collect what I can befor it goes threw the motor.

Guys will say why not spend money on peace of mind you bought a $65k truck blah blah blah- well you’re spending decent ($300-500) money on a “mod”
That fo sho has not proven to alleviate/prevent/hinder/fix any problem. Unlike the companies that want to sell you tires, super chargers, headers, downpipes, hell even CAIs- there are no before/after dyno results, no temp readings/heat scans, no oil analysis, no times - nothin. Just a little frothy substance accumulated in a lil can over thousands of miles.

In theory IF we weren’t running port injection on top of DI there may be something to a catch can- BUT- you’re drilling holes, running tubes, catching the eye of the service techs for no “good” reason- ain’t making the truck ride better, pull harder, stop quicker or even look better.

If it works- why hasn’t a company been able to pit 2 otherwise identical trucks against each other over 25, 50, 100k miles and say LOOK we “saved” a tangible amount of HP/performance/economy by running this catch can- HERE are the results.

Nope you won’t find any of that, but you WILL find a thread on here where someone started throwing codes from a catch can & having dealer trouble tho....for nothing but a frothy 1/2 oz of oil. I’d rather take my $450 & get a tune, or some eibach springs, or a CAI, or hell a good time @ the ol strip club. All of em are better uses of your $$$

This is the best interwebs advice I've ever read. $450 at the strip club would get you a limo ride, so I hear

I’ve never found a need for one and many instances feel like they can cause more problems. Even coming from a gen 1 ecoboost I never ran one. If anything putting more check valves or changing routing can cause more of a restriction to ventilate the crankcase. And if one of the check valves fails then you will have a bigger problem. No one knows for sure how much a catch can truly saves your engine. No ones run one long enough for proof. But there are many ecoboosts out their without them in 300,000+ running strong. Everyone can argue oh I caught this much. Yes congrats you caught some gas vapors that have condensed. But think about if that catch can didn’t lower the temperature. Then that would’ve stayed a gas. You wanna spend the money go for it. Theres a reason ecoboosts run so hot at about 205-225 and that is to allow the gases to be burned up. Ford engineers designed the engine to have slight valve overlap to help with blowby. Just gave my 2 cents.
Happy Modding

First

Your truck. You do you. This isn’t a criticism.


6000 miles at roughly 15mpg is 400 gallons. Roughly 7 55 gallon drums worth of gas. WAG an average speed of 45mph equals 133 hours of driving.

That tiny amount of crud vs the large volume of fuel and time doesn’t seem “worrisome”.

if it were truly needed...the ford or any other car companies engineers would have included it with the car. Think about it.....not a single car manufacturer includes a "catch can" stock.

They could make them big enough to hold an oil change interval worth of fluid.

Even the picture with a jar of gunk shown a few posts up....now divide that by the 3,000 miles it took to accumulate and then x the 2,000 average rpms over each of those miles. the amount of fluid passed through the intake for any given RPM is so small, it does not matter.

Just my .02¢

ANother valid point. Also consider this - IF they were the "end all be all" problem solver for blow-by/coked valves etc. then why on earth would they go through the MUCH MUCH more expensive route of re-engineering/R&D/Manufacturing a secondary port fuel injection system & adding that to the HO 3.5 EB vs. just adding a pretty catch can w/ the blue oval logo on top? WAY WAY Cheaper route & they could turn around & sell 'em for big profit to all the "lesser" EB engine equipped vehicles - they like selling their performance diff covers right?

That FACT alone pretty much tells me all I need to know. If I wanted more confirmation I'd look @ how BMW, a company who went through MUCH worse publicity/problems due to DI in a FI turbo platform....did they add catch cans to the new N54 or whatever it is 3.0? Negative. This is a company that walnut-blasted my buddy's 335i TWICE.

No. If you needed a catch can, I am sure the ford engineers would have put one in.
