6.0 Cylinder fills with fuel, consistant raw fuel out the tailpipe

Any help would be appreciated. Truck was made 8- 2003

Truck has 486,000 on it (6.0) and when the truck sits for awhile it hardly cranks over because 1 (or more) cylinders fill with fuel. Fires up eventually after letting it sit.

Let it sit for 1 1/2 hours fuel does not get into the cylinder, and cranks up just fine since its not trying to compress a liquid. Still dumps raw fuel out the tailpipe

Raw fuel coming out the tailpipe all the time, but it runs and drives. Looks like white smoke and some black smoke mixed together. This is at a idle, did not bother revving it up. Guy i purchased it from says he just drove it back 250 miles getting 6mpg.

Engine oil is dark, not excessive, looks like normal used oil, does not smell like raw diesel, no fuel in crankcase from looking at it...

Slight miss, id have to spend more time with it to get all the particulars.

So, id asssssume it has a stuck open injector, or a bad o-ring on some injectors.
Could i pull the glow plugs and crank over the engine and see where it comes from to help pin point the bad injector??

Would the EGR cause the truck to dump raw fuel into the motor? Cracked intake manifold?

I do not have a scanner currently, can i use a horsepower box to try and pull codes? I have access to a hp box,,, superchips?

I also have a 7.3 psd with no issues, i am familiar with diesels, just not a whole lot with the 6.0 ....

Links, hyperlinks and plain english (no acronyms please)

I will buy someone a STEAK AND LOBSTER DINNER if we can fix it

Thanks for your guys help.

Yep, a stuck injector or injectors.... I would do a contribution test to see which cylinders stops the constant stream of fuel. Then look in the cylinder with a bore scope through the GP hole for damage. Then replace the injector. You got ALOT of miles out of those injectors.... Please try not to run this truck until you get it fixed as the excess fuel can melt the pistons and destroy the valves... the superchips tuner, if it can pull codes would help diagnosis quite a bit too.

Only an injector issue will dump fuel into a cylinder or a head issue [you do not seem to be running hot enough to unseat the heads] so I would go with injectors. The glow plugs work well for locateing the cylinder/s affected pull em and roll her over and see where she spits. As a side note ya can have a bad injector in this situation and show no codes unless the scanner can show a cylinder misfire from cylinder contribution.

Thank you guys, ... Sounds like ive got my hands full.

I will search what a contribution test is and how its done...

I havent driven it, hopefully not too much damage yet.....


Hopefully, i was just reading and seems like i can do this at work tomorrow.

"Sounds like the classic 6.0L injector stiction issue, Another quick and easy test you can try yourself, is to remove the secondary fuel filter and fill up the housing. Crank the engine over with the key out of the ignition, by using the jump starter on the passenger side of the engine, and peak inside the secondary fuel filter housing for the presence of bubble(s). If bubbles appear, it means you have compression gases leaking into the fuel system. "


Thanks

That's the most miles I've heard of on a 6.0. Any idea on the history of the truck?

You forget the hyperlink????

Please repost what you were thinking of, thanks bud...



History of truck, it used to be owned by a guy who drove it alot

I just purchased it broken. Hoping to get it running and possibly hit 500,000 miles would be neat.
