A beast with problems........

[BubbasBeast]

Ok guys, new to the site and, well, new to diesel trucks. Bought a high mile (104800) 08 F450 to serve as a tow rig for our newly aquired 5th wheel home away from home.

We start this saga with enough regens to choke a donkey. Around town I was in regen at least 3-4 times a day. Went to the stealership, where the service writer advised me to do a DPF delete. Ok, read TONS of threads on the site, saw similar folks with similar issues, and dove into the DPF delete.

H&S Mini Maxx, DPF/DOC pipe completed. Problem solved right! no.....

So now the truck has white smoke that emits from the exhaust once the motor warms up. Heavier on throttle. Smells like coolant. Great, ordered the Sinister EGR delete kit. Can't hurt, the mini maxx already has the EGR turned off anyway. Guess I know why it was clogging up the DPF so much.

Interestingly enough, when I looked at the DPF closer, it had a replacement date written on it of 10-15-2011. Now I'm wondering if the previous owner had it worked on under warranty and they failed to diagnose the real problem and just threw a new DPF on it?? Trying to get the Ford service records now. Not that it will do me any good, Ford will still deny any further warranty work.

Fingers crossed, more to come.......

Hate to say it...but I would almost trade the damn thing back in right away if you can.

Trading back in is not an option. Looked at the smoke in the daylight today, it's blue, not white. Going to the stealership tomorrow for the verdict. If it needs a motor, the DPF/DOC is going back on and looking for another truck. Wish I had read more about the 08 6.4 before I decided to buy one. I love Ford, but this really puts a bad taste in my mouth.

So the dealer called. The blue smoke is not from it burning lubricating oil, but is from overfueling from my H&S Mini Maxx. Reloaded the tune to make sure the low boost fueling was set to 0 (it was), still smoking. Request sent to H&S tech support, nothing back yet. Any idea guys?? Anyone else "overfueling" with an H&S??

[jim_patterson]

overfueling would be black smoke. some oem/dealers call it overfueling when you do things to bump up the hp, like a tuner which adds more fuel.

blue smoke is a sign of burning oil

[BubbasBeast]

According to H&S, not their tuner doing this. I should clarify blue, the smoke is white with a blue tint. I have never owned a diesel, so not sure what running rich looks like. Going to try video recording tomorrow. Also going to go to another diesel shop and see what they think. Dealer wants me to put it back to stock for them to try diagnosing again.

Driving the truck this morning, light white/blue smoke from exhaust. Took off from a red light and heard a loud groaning, almost like a power steering pump under load, and noted a HUGE cloud of white/blue smoke. Groan went away and so did most of the smoke, although still has enough to see under part throttle. VGT issue?? Injector sticking?? ARGHHHHHH

[BubbasBeast]

OK, need some help here guys. Using my H&S, I have been watching the fuel flow numbers. If you have a H&S or comperable, can some of you guys show me your flow numbers for the following conditions.

No Power setting, (1) numbers in park with engine running, (2) trans in drive, foot on brake, (3) steady state 25 mph.

I am flowing as much fuel at a red light as at 25 mph. WTF?

too hard to say for sure, could be an injector or a turbo leaking. both will do pretty much the same damn thing.

can you pull your downpipe off at the low turbo and take a look into the housing?
