Carbon buildup at 25k miles - A short story

[NOVA_Ranger]

Holes shots leaving stoplights is my preventative maintenance for this. No issues or concerns with buildup so far!

Alright, 50k update:

- Odometer reads 49,400 mi
- Last 25k miles has been mostly highway driving
- I've continued to use Vavloline full synthetic 5W-30 at 5k intervals
- It's an absolute PITA to get these pictures and I'm thinking 100k will be the next update (If I still have the truck).
- I drive it like I stole it

That's great news. Thanks again for "scoping this out".

I know there are no dumb questions, but...
(yeah, I know, yes there are!)
I don't read all the threads so here goes.
Is the possible build-up of carbon on the valves the main, and maybe only, reason for the catch can mod?

BTW, OP, thanks for your highly, fact based, informative posts.

Finally a thread that reduces my anxiety about my truck lol

I would say Yes, it is the main reason... but then there are also people running catch cans on dual injection engines. The general idea is that you're keeping all the nasty contaminates from the positive crankcase ventilation from recirculating back through the intake. Proving that it does anything useful is a whole separate argument.

Now all we need is a transmission life indicator...

Hard for me to tell what I'm looking at.

You know, I bet if you took those photos to one of those macro-print graphics places, the kind that make large scale vinyl posters and marquis', you could sell them as modern art; museums will beat down your door to display your work!

Thanks for the effort!

I thought Sid had stepped up to do that.

Is the OP using the stock paper air filter? Also, doesn't the R5G have some sort of stock catch can?

It has an oil separator that should do something similar to a catch can but drains back into the sump. Since the fuel quality is of lessor concern for this issue, I am spending extra on better full synthetic oil with a shorter change interval.

One useful thing is it makes money for the people selling catch cans... well... useful for them.

Why did Ford add the oil separator to these motors... if it didn't do anything?

And where are all the reports of these motors having coking issues? That would have reared it's ugly head by now, but it hasn't.

My hats off to Ford. Looks like they corrected the issue that plagued the earlier design ecobeasts.
