3.5 Ecoboost Carbon Buildup

[wasinger3000]

I've been running techron quite often but I know bg44 is what I need to get.

Somewhere on a 3.5 teardown I read that these engines inject a miniscule amount of fuel during the exhaust stroke to help wash the valves. I just can't find the page anymore. Not sure if it's true.

Either way the only "fix" right now is a meth kit.

I do run lucas UCL. Not sure if it helps or hurts the carbon buildup. But I do get around 2-3 mpg better on the highway.

Impressive gain!

Yeah it is surprising. Doing 73-74  mph on interstate I get 27 mpg. Anything after 74 and the milage drops off. Coming back from Denver I was getting 29 mpg. Considering it's a gradual decrease in elevation to ks it's expected. I'll post pics of my trip meter next time.

I did the seafoam a while back with no apparent I'll effects. It actually felt like it ran better after I was done. Just use it slowly like I did over about 15-20 min. I used about 1/2 can. I plan on doing another soon. I will do a before and after on the valves.

You values looked fairly carbon free.  But they seemed wet . So oil is getting to them.  I wonder if changes where made to system for the 13 refresh?? ?

Have you tried using the deep creep stuff by seafoam? It's supposed to really break carbon down. What I did was take the map sensor out and sprayed into each venture of the manifold in hopes to cover each valve.

The second video was after I sprayed seafoam on the valves so it looked glossy. But they still had a liquid oil sludge on them so they are getting contaminated somehow.

I wish I could put the camera down the manifold while it's running to see if there is some kind of blow back into the manifold.

Also I wonder if it's possible to atomize seafoam so it can be sprayed into the manifold like a fog.

I'll try to make something tonight using compressed air and some kind of nozzle.

This is what I used,

It comes with a tube that is slid under the intake tube just before the tb. And this allows you to slowly add the seafoam to the intake track. Almost the same point of entry for the meth kits I have seen.

I forgot they made that straw. I'll have to find one.

Here's what I'm using.

As a suggestion for a kit, I wouldn't try this at the normal price of $49.99 but it is on sale for $24.99 with a $10 rebate. Makes a nice filler for a Amazon order, cheap enough to keep a couple on hand.

This kit was just on Woot for $13.99, hopefully will be again.  Keep an eye out 4 it.

Yeah was going to post the thread. But it looks like it's sold out.

I just made an appointment for the bg intake service for Friday.  I'll post some pics of the valves after.

I'm having my cousin enable the awd gauge this week. When. I'm at the dealership I'll ask him about the carbon build up on the 3.5 and what he does and or is told to do about it.

What the tsb says and what the mechanics do differs sometimes.

With the $10 mail-in rebate it gets it down to $14.99, It seems like a clearance out on the kit due to a updated product package.
