Carbon buildup at 25k miles - A short story

[grammat95]

Thanks for the post. I bought my ranger mostly for towing too. I have a boat, the boat+trailer is ~6300 pounds (hopefully will be down to 6000 before I start taking it to races).

I got a used low miles ranger and it ended up 'decked out' in Lariat trim so I'm rather enjoying it as a vehicle. Have a small car to get me around for the most part, though. So mine will be similar: lots of miles towing I think, but much less driving overall than you. Looking forward to your 50k update so I know what to expect!

BTW what does your trailer rig weigh? I saw your other post about it, is it a 3600 pound excavator plus ? (~2500 pounds?) for the trailer? Curious if you ever weighed it on a scale.

The trailer weighs right around 4k. I've never weighed it on a scale. The Ranger pulls that setup very nicely with the combination of the redarc brake controller.

Holy cow, so your total setup is around 7500 then, plus or minus? That's amazing.

Yes, I've never had an issue towing at max capacity. I think the 7,500 number is fairly conservative... depending on shape/wind resistance of your trailer.

I didn't want to start another thread, because I see no need to for a simple question.
Does running at higher RPMs on occasion help burn off carbon build up?

Sadly, no. You need HIGH quality fuel on the back side of the valves to keep the valves clean. That doesn't happen with this engine design.

Yeah, I was reading about the need for fuel before the injectors to keep them clean.
Thanks

I'm watching these carbon threads closely. I ordered a catch-can system for my 2020 Escape, but have yet to install it. I WAS going to order a catch-can for my new 2022 Ranger, but cancelled the order at the last minute.

I have a friend that is a Ford Senior Master as well as an ASE Master Automotive technician. I've know him for close to 30 years, and if I still lived near him, he'd still be the only tech that I'd let work on any of my vehicles.

I asked him about adding catch-cans, carbon build up and the direct injection. His reply to the carbon build up was that folks that hare having the problem aren't changing oil as often as they should be, or they are not using a quality oil. OK.....I get that part!

In regards to the direct injection, & I think I may have to call BS here and I think he is mistaken......he says that the 1.5L and the 2.3L engines that I have in the Escape and the Ranger have both direct & port injection. Anyone heard or that? If that is the case, then I am not going to mess with installing the catch can on the 1.5L nor bother ordering one for the 2.3L.

You are correct to call BS. While Ford does have engines with both port and direct injection, none of the Ranger or Escape engines do at this time. Switching to full synthetic oil will reduce oil vapors that get caught up in the PCV system and get reintroduced via the intake manifold directly adjacent to the #2 and #3 ports. I added a catch can to my 2019 Ranger as an added precaution as well as switching to a premium full synthetic oil.

Update: Im at 45k miles now. Shouldn't be too long before the 50k update. I'm going to try to get some better pictures this time.

10-4. The 2.3 EcoBoost is a GDI (gasoline direct injection) design.
Pro: the piston only has to draw air on the intake stroke, yielding less pumping losses from the less dense air. The fuel being delivered separately creates more turbulence during combustion yielding higher performance(economy) and more complete combustion.
Con: there is no fuel being pulled past the intake valves cooling them and "washing" them clean.
GDI injectors have very, very small orrifices, as tiny as 800µm (800millionths of a meter) delivering fuel at around 2000psi into a hot combustion chamber, and clogging can occur if running E-85 gasohol

May be why it says not to use anything higher than E15?

I've logged over 3,600 PSI of fuel pressure on my Ranger.

Ethanol will more likely clean the injectors, not clog them. Now, if they clean deposits in the fuel system (that is unnecessarily dirty), it can carry that particulate to the injectors.

been thinking about getting a borescope. Have need on my Harley. What model do you have? is it fuel, chemical immersion proof?

Would love to see same photo at same milage on a truck with a catch can installed.

Yes that would be great. There has to be someone on here that could help us out with that...

This Pennzoil is, along with the Valvoline, a great synthetic to run in a GDI engine due to its ability to resist evaporation. Will be less sticky over time according to Todd. Based on this video I decided to order the Pennzoil 5w-30 for my oil changes.
