Is it too late?

I bought my 2017 SCREW Raptor CPO with a little over 48k miles on it. It does not have a catch can. I'm looking to purchase and install the JLT V3.0, I'm wondering 1) is it too late? 2) is there anything else I can do (engine cleaning wise) to help maintain the engine.

slick truck. from all the threads ive read on here the gen 2s do not respond well to a catch can. the theory of the cans are great but at the end of the day if the ford engineers thought the engine needed a catch can they would have installed it prior to mass production. With that being said if you start messing with the motor, tune, bigger tubor, air intake, and so on then sure you could benefit form one at the 100k mark. If the motor is at ~40K now then it should be good. as in any of the known issues would have shown face by now. best thing i would suggest is put any money you want to dump into suspension, bumpers, radios....leave the motor alone, just keep up with oil changes and topped off fluids and youll be good to go.

If you want to install one, it’s not too late. No such thing, really. Any oil that’s been blown/sucked by has been burned. Whether it’s ended up as carbon deposits on the valves is the debated point, but adding a can now would catch what’s going to go through from now on.

I plan to install one. I think. But, either way, it doesn’t appear to be a life-and-death issue.

As far as taking care of the engine in general, buy quality fuel and oil, and change the oil regularly. 90% of engine maintenance is in oil and fuel. The other 10% is taking a few minutes to actually look the thing over, thoroughly, every once in a while, to see if anything seems amiss.

To my understanding the 3.5 HO motors have BOTH direct and port injection. The buildup was a bigger issue on the non HO EcoBoost motors that only have direct injection. so the back of the valves are dry and would collect deposits. On our HO motors the port injection side washes the back side of the valves with the air/fuel mixture keeping them cleaner. Hope that is the correct explication!

Nice looking truck, congrats.

Catch can not needed at all.

Not too late, but more importantly, not necessary.

Change oil per the manual or earlier, use Motorcraft filters or better, change air filters twice a year, warm engine before stomping on gas pedal, let idle for a while before shutting it down, have fun. Beautiful truck!

There is no need to let it idle before shutting down. This isn't 1985... turbos are water cooled and coolant circulates after engine shutdown. Do you really think this thing would have start/stop if it was harmful to the motor?

I was trying to help the man out. No need to flame.
