SLOW TAKE OFFS?
Hey guys, so just bought a 2004 F350 6.0 powerstroke, reg-cab 4x4 auto. So here is the problem, when I hit the gas from take off or hit the gas going 10-15mph, it takes off very slow. Its more of a take off like if you where driving grandma around. When im going 20 or faster and hit it it takes off real nice like it should, from what I can see the bad parts that made many people not want to buy a 6.0 have been changed out. Anyone have any ideas for me, I want those nice fast take off like in my other trucks. Also I ran a check and no code came up. :argh:

You might need to clean the turbo, any mods to the truck?

turbo lag. most stock 6.0l truck with no cat/muffler have this. To fix it i put a tuner on mine. Now i can smoke a set of 35x13.50 mud tires from a dead stop. although at $1700 a set i try not to.

This is the up pipe to the EGR cooler, as you can see, it scavenges exhaust gasses and we all know how a turbo works. When I took this out for an EGR cooler delete, I found some low end throttle response, even in stock mode, more so with my SCT on SRL from Gear Heads. I suggest you search EGR coolers in the Diesel Bomber search engine for more details. If it's all stock, gauges, an SCT (SCT Live Wire does gauges), EGR cooler delete, and a 4" turbo back will really get things rolling for you. If you live in a smog area, a 3.5" down tube, 3.5" cat, 4" cat back would work too. |
Stock 6.0's with no tuning have some terrible turbo lag. Start with an EGR delete like Karl said, then tuning. Should wake it up quite a bit. Keep the tuning mild until you can afford studs/gaskets. A street tune should really wake it up. Great throttle response, almost smoke free, and makes it a lot more fun to drive.

Get ready to break that wallet open. EVER since I have join this site I have bought a handful of guages and other nick nacks.... and I haven't even put my AD or sct in the shopping cart yet... These guys twist your arm over the internet OR at least make you justify the reason to purchase the extras :argh:

It's easy for us to spend your money for you too! :c:
Start with the turbo cleaning and an EGR valve cleaning, those two things alone are nearly free, just some of your time, and whatever beers you consume during the process. Those should help right off the bat. Start there, it's cheap and easy. |
If you haven't found out by now, the lag is due to the turbo sticking. I had the same exact issue you were, after doing some research on how a diesel works, i found turbo cleaner. Only down fall, they dont sell any of them in the U.S. Shping is thee killer. After i found out how they work, I bought Seafoam Top Engine Cleaner Sea Foam Spray - Sea Foam Sales Company and stopped every issue in one use. With the truck running, spray the entire can in to the turbo just past the MAS. You will hear the engine sound different while you're spaying. dont turn it off, replace hose, and go driving for about 20 minutes. My MPG was 9.6 city/16.1 hwy but now its 15.5 city/19.2 hwy.......and NO LAG!

Jim’s answer: Sorry to say that Sea Foam Spray Top Engine Cleaner and Lube cannot be used in the air intake of a diesel engine. I do not know of any cleaner on the market that can be used for cleaning diesel engines through the air intake, unless you’re first removing the air intake from the engine. You cannot spray any flammable liquid into a diesel engine. Instead, you can use Sea Foam Motor Treatment as a safe fuel additive for cleaning and maintaining diesel systems. |
Sea Foam "Top Engine Cleaner" is non flammable and non toxic. I did the same processes and the other turbo cleaners i found, such as Revive and Forte, and it fixed my truck. Just remove the intake hose between MAS and the turbo (dont spray toward the MAS) spray half the can @ idle and half with the high idle on (to move the vanes.) Get on the highway and punch it. You will see the carbon s (white smoke) coming out the exhaust when get enough boost for a few minutes. All I know is, i keep my foot in it now just to hear the turbo scream. lol!

I"m fearful of spraying that stuff into my turbo becasue Seafoam says NOT TO do so on diesel engines. I may get the seafoam and put it in my tank.. my turbo runs fine so I"m good.
|
there's probably a good reason Seafoam says not to use it in a diesel, I would hate to find out the hard way.

I'm with you Big Brown ;)
Now if MudDub said it's ok...I would listen to him since he has a TON of Experience and knoweldge about the ford 6 liter. No disrespect to you guys, but his experience is someone I had always trusted ;) |

I had to replace my oil cooler and did a few upgrades while I had it tore down. Since I had the turbo off I decided to clean it and found my unison ring needed replacing, so I rebuilt my turbo also(extra$100). Which brings my to a couple of observations about spraying any type of cleaner into the intake. 1) Any cleaner that gets into the turbo thruster bearing would probably not be good. 2) After removing my intake, soaking with it degreaser and blasting it out at the car wash, you really would be surprised about the amount of large chunks of crud that came out of it. A large crud chunk that gets stuck in a valve would not be good not to mention what could happen if it passed through and bounced around on your turbine. I am far from a diesel mechanic but I do question how you can eliminate turbo lag with a can of cleaner when my SCT tuner only reduces it. It might just be perception, I really don't know.

Gotta agree with clean, but be careful with sea foam in fuel. The stuff does a great job, but you need to add 2stroke oil for outboards to retain some lubricity for injectors. I would research other cleaners and find one you like such as optilube for cetane boost and cleaner all in one additive.there is a lot of info here and other good forums for diesels.

Funny, I used to use 2 cycle oil in my Duramax, but I"ve yet to use it in my 6 liter. Is 2 cycle oil in the fuel OK for the 6 liter's? How much if so?
Thanks guyz ;) |
Opinions vary. I use about 8 oz to 25 gallons just for a little lube for injectors. I figure its meant to burn clean and lubricate outboards. . I don't see it hurting unless you add enough to thicken your fuel. . Seems a little smoother and runs well for what it is so I will keep using 2 stroke outboard oil.
