Archived Diesel fuel puking out front breather (pill bottle)

[proflow]

I drove this (new to me) 01 CTD to town today & when I stopped to dump some trash I left it running. I smelled fuel & looked under the truck. Holy crap.

There is a 5/8 hose coming off the breather on the front of the engine down near the front diff. Its ******* fuel out like a garden hose.

Is this a stuck injector or ? I have spare stockers if so.



Any info would be great, i have to drive this thing in the A. M. Hopefully.



Thanks---Proflow

not an expert, but sound like an injector.
chek oilt to see if its fuel or antifreeze. that will help

 

[Nyoest]

Could be a loose or leaking fuel connector tube. Try retorqueing the injection lines at the head. That won't be it though, too cheap and easy.

 

[proflow]

I'll go check the oil again & the injector lines as well. Thanks guys, I'll post back. ---Proflow

If you've got that much diesel in your oil, it's time for an oil change before you wipe out your bearings.

 

[proflow]

No leaking tubes up top.



I'll swap the injectors & see whats up.



I did pick up 12 qts of Rotella & a Mopar filter @ walmart knowing this may be the case.



***** Too weird, I just checked the oil again before pulling it into the shop & its exactly where it belongs & has NO signs of deisel fuel. *****



What up ???

Swapped out the injectors & got the same damn thing.

Is this possibly VP pump related or ?

The VP was changed out recently at the prior owners expense.

Any chance a cracked injector tube ? Do those tubes just pull out ?

Seems almost like they are spring loaded or something.



I'm kinda at a loss here. Any ideas ? Where to go next ?



Thanks---Proflow

The 01 has the crank breather bottle on the front timing cover. The front diff has the fuel filter water drain above it, which in turn would act as a drain rail for any fuel dripping above it (filter lid, return line, banjo bolts that are loose etc. )

Clean and dry the whole left side of your engine around the VP and filter housing & transfer pump. Start the engine and watch to see where this dripping is coming from. You have a fuel system leak somewhere.

On Edit, #6 injector line at the back of the head is notorious for never getting tight enough given the lack of room for any leverage, but that would put your dripping at the rear of the diff off the bell housing.

 

[Lurch]

um, could it just be your filter drain stuck open?
It's happened before.

 

[proflow]

Crank breather bottle on the front timing cover is ******* fuel out of it bigtime. The fuel filter canister hose is nowhere near where this add on 5/8 hose is ran. I'll clean everything later today & have a better look.



Thanks guys---Proflow

Odd.

If fuel is indeed coming out the timing cover/crank breather port, then your oil level should be... just about coming out the dipstick tube.

Any internal VP44 seal failures at the input shaft would/should cause any fuel to be blocked and diverted by the gear to go to the pan, not out the breather.

I have a truck in my shop right now with the same exact problem. The owner just installed a new VP and accidently got the keyway off set and pushed it back into the VP. Well at least that is what we suspect. It will break the seal on the VP and it will pump fuel into the gear case. Blows it out the blow by tube and fills the oil pan as well. Can't believe you have the same problem.

Fuel Filter Drain

Have you checked the drain valve on the fuel filter? I once bumped my drain valve while adjusting the idle stop. Fuel leaked like crazy. Also one time the fuel retrun line sprung a leak and had fuel washing down the side of the block.

 

[KcoleKennyc]

It doesn't make any sense for fuel to be coming out the breather tube and none is in the oil. With that much leaking, some would have to go in the oil pan.

 

[DieselLady]

WE will be pulling our VP out tomorrow and see if we have problems with the front seal of the pump. .
Will let you know.
BTW. We have fuel coming out of the vent tube, also the dip stick is up over and inch over full. The rocker arms are like fuel soaked. Fuel everywhere.

 

[proflow]

Got it all cleaned up today, tomorrow a. m. I'll pull the crossover tubes & maybe the VP.

With this thing ******* as much as it is, I almost think its too much for just a crossover tube. Any thoughts on this ? I'm on the fence what to pull next for likeliness.



Thanks---Proflow

 

[p-Bar]

I think DieselLady has the answer for you

 

[proflow]

I dont know how I missed that post but I did.



This is now making sense. I totally agree.

Time to pull the recently replaced pump & see for sure now.

Its weird the 2nd day I own this truck this happens, there were no signs of fuel puke the day I bought it. go figure !



So I spose the key got somewhat pushed back & then the seal finally gave out ?

I'll know for sure tomorrow.



Is that seal something I can get from Napa ? I hope so.





Thanks---Proflow

 

[DieselLady]

Well we will be pulling the pump at the same time, And no, you can't get it at Napa.
I am going to check at a couple of places that I know can rebuild these pumps. Hoping they can just replace the seal for a much lower price. Since the pump is new, and works great, I am keeping my fingers crossed,,,, for my customer. Otherwise, it is going to cost him another $1100. 00 on top of all the labor. He has already bought the pump once and also an Air dog. I like having the work, but not like this.
Guess we will be reporting at the same time.

 

[proflow]

Thats not good news about the seal, I was hoping it was an O-ring or whatnot.

Its been a little while since Iv'e replaced a VP.

I did print out Blue Chips directions just for a refresh & torque specs.

If that seal is trashed & not available right quick, I'll have to pull my other pump from my 02' truck.

So if a guy was able to get a seal, would the key likely be reusable ?

Seems like Ive read a few different times in the past about them being picky for timing.
