Major Problems on Gen 2

The dual can setup covers the CCV not just the PCV. That's why you run a dual can. The dual valve only covers the PCV but allows you to get suction on the can both on and off boost.

From all my research, It doesn't all get burned, it will find its way to the intake tube, mass air flow sensors, intercooler, throttle body, etc.

Only clean air is what is originally designed to be in the intake, it used to be released to the atmosphere but the EPA changed that.

None of that blow-by no matter how small doesn't belong in an intake of a vehicle.

Techron is also a great product. I have used it many times over many years in many vehicles. It really works. I typically use it before every oil change.

As for the matter at hand (catch cans), I think of them as cheap insurance to maintain performance over the short and long term. In the short run, the oil vapor reduces the effective octane level of your intake charge. That's not good in a high pressure turbo motor. At best, your truck will pull timing and you will lose power. And in the long run, catch cans can help keep your intake ports, valves, and pistons from excessive carbon buildup, which also robs horsepower.

Do you really want your truck to end up like this one...

"In May 2017, just after completing its 1000-mile break-in period, our Raptor vaporized the 60-mph mark in 5.5 seconds and bulldozed its way through the quarter-mile in 14.2 seconds at 97 mph. By June 2018, some 39,000 miles later, it added 0.5 second to both milestones and lost 4 mph from its trap speed. In the wrap-up test, the truck needed an additional 2.5 seconds to reach 100 mph. Some of the Raptor's horsepower, it seems, had disappeared as quickly as seven BFGs and 2850 gallons of gas."

I never had a problem running my JLT catch cans on my Gen 1 or Gen 2. I don’t understand why guys try to spend hundreds of dollars on a catch can when it is a simple straightforward design. So yea, if you spent $300+ plus dollars for one, then you wasted your money. The JLT catch cans are sufficient and do their job with no warranty issues and/or throwing codes.

@goblues38 is partly wrong and partly right. All the excess oil and gas blow by doesn’t get burned up in an engine. How do I know? Tear apart any engine and you can clearly see what side of the engine the PCV was on and what side it wasn’t on as the blow by is evident. Does that mean that the excess oil/vapors will ruin your engine? Yes and no. If you don’t run top tier fuel with fuel additives, and quality oil with regular oil changes, then yes the blow by can accumulate over time and cause problems. But if you do all those things mentioned above, the likelihood of you having problems is slim. Moreover, most Raptor owners will NEVER keep their trucks long enough to have problems.

Vehicles nowadays can run 200k miles easily while not being maintained very well. Does that mean that you shouldn’t maintain a vehicle to the best of your abilities? No! Lol it amazes me some of my work fleet vehicles—currently have a 05 F150 XLT with 400k miles on the transmission (never been serviced). Does that mean that one shouldn’t do transmission flushes and change the tranny filters? No because someone who has regularly serviced their 05 F150 transmission is going to be in a lot better condition than what mine is in. In a similar way, catch cans will play a greater factor years down the road when the vehicle is older and out of warranty. How big that factor is is debatable. Nevertheless, they do work and alleviate oil/vapor build up. Tons of people on this forum have been using them for years with zero problems.

When is the last time you actually tracked it?

I've heard that if you use fuel additive or improves it will clean those deposits..such as Amsoil PI... my Raptor has 2300 miles I will try it when it reaches around 4000 miles. Has anyone ever used them ?
