Before I even took the cover off of the Ecoboost, I poured a whole can while the truck running through the brake booster line, which I believe is correct, but the line runs all the way back behind the motor on the passenger side. I think I did it wrong. What is that line that runs to the back of the motor???

 

first question, why would any ecoboost out there need seafoam already? do you put that many miles on/year and drive the first one off the line?

 

I usually do it every 25000 miles. On my previous vehicles.

 

That was my thinking

 

Need a bigger picture to see what line you're pointing at...

 

Is the truck running any different? If not, I would say keep driving it and don't worry about it. Also, If I'm not mistaken (It's been years since I've had to Seafoam a vehicle) but if you did it right, should have hade white smoke pouring out of the exhaust?

 

It will only smoke, if there is carbon to be burnt.

 

Don't take this the wrong way, but what did you expect to gain by doing that? It maybe helped in the 1950's.

 

Carbon is going to build up regardless. I haven't ever seen a vehicle that didn't. Supposedly when you use seafoam it helps to clean up the carbon making the vehicle run smoother. I think that line runs into the oil portion unless it is some kind of electric pump/vacuum. I'm going to have my oil changed tomorrow though.

 

Seafoam is something you put in the gas tank of a carburetor'ed engine.

Like my motorcycle for winter storage, a gas powered lawn mower...etc...

Why would you need it for a fuel injected engine?

Edit: Okay, I guess you can use it for FI:

Also, it can be used as an oil additive - not just fuel - didn't know that.
