If it was the dealer they were more than likely going to use mopar combustion chamber cleaner and a fuel system cleaner (mopar or bg44k).

I recommend that you go out and buy the combustion chamber cleaner and grab a couple cans of mopar injector cleaner or bg44k.

 

This is great information everyone. Going to look into all suggestions. Sea foam sounds interesting.

 

That there is some good advice!

For seafoam just like he said, a lot of guys do 1/3 in gas tank at fill up, 1/3 in vacuum line, and 1/3 in engine (about 50 miles before oil change.)

There are really great detailed instructions on the web.

 

Yea everybody seems to like the stuff so I'm going to try it this spring.
As for the pcv system. The valve is right beside the throttle body but the system itself is enclose. On the 09 and newer trucks it's possible to add a catch can to separate the oil vapors. On the 03-08 the oil just condenses in the intake. Over time it will build up. This would make adding the seafoam through the vacuum line quite important.

 

Unfortunately, due to the economy and lack of construction in my area, and lack of funding to finish school, I now work in an auto parts store. Everyone I associate with in the company (a few stores nearby) several DIY'r's and several of my commercial accounts swear by seafoam. Like mentioned, there are directions on the can, and even more on their website, as well as threads on here that explain how to use it in many ways. Pouring some in fuel cleans injectors, pouring in intake through vacuum hose and letting sit, gets it into the top end of the engine and soaks/loosens/breaks down all the carbon build up on the valves chamber; and pouring in the oil removes buildup from oil gullies and such. If trying the second two options, make sure to plan on changing your oil very soon. If there is enough buildup in the gullies, it can loosen as a clump and go and clog something else, block oil flow completely to that area, and that is NEVER good...pouring in vacuum line and rinsing all the carbon and soot buildup right into the oil pan, and you will be grinding it between piston rings and cylinder. Don't get scared, just use caution, and be sure to drain the stuff out soon. You will hear of some horror stories, most likely related to the issues I just mentioned, but I will bet, whether they want to admit it or not, the misused the product and didn't drain the contaminated oil. You will hear MANY MANY MANY more good stories than bad about the stuff. It was mentioned to drive about 50 miles...I don't think I would, not the first couple times at least, it seems too long...just pour it in, let the motor idle till normal operating temp then pour in vacuum tube, let soak 5-15 min and fire back up for a few to burn out the loosened carbon, let cool and drain the oil for the change. If I've scared you about blocking gullies, then refill with cheap oil and filter, run it a few hundred miles and drain, see if it picked up any remains...if not, should be good to go, put your normal oil in and drive the normal miles til your next change, and repeat the seafoam just prior to changing, after a while it prolly isn't necessary at every oil change, but you'll want to do it a few times in a row to get the initial cleansing.

For fuel injector cleaning/maintenance, I use this Star Tron http://www.tractorsupply.com/en/stor...reatment-16-oz stuff that can be bought at Advance Auto Parts or Tractor Supply. Hammer recommended it on a thread here, I tried it and his claim of 1-1.5 MPG gain is accurate. I now use it at every fill up. It cleans as well as adds a bit of extra lube that gets removed from the ethanol content of fuel, and probably a few other things that I don't remember, but I am sold on it.

Lucas is another well known FI cleaner, I have used this a few times in the past, and I didn't get any noticeable results, so in my experience, it doesn't work all that great. May be it just isn't real effective on our trucks and other vehicles get more from it, or maybe I keep mine pretty maintained and clean from running only the recommended 89 octane.

 

Yeah. Sorry.

I didn't mean that anyone should try to drive 50 miles with seafoam in the engine before an oil change.

What I was trying to say is don't drive more then 50 miles with seafoam in the engine and certainly less miles would be more than fine.
