Help Needed The 99 is smoking again.. Why?!?!

[SD70M]

My problems started, soon after I bought the truck. The PO ran WVO in it and I run a WMO blend. Soon after putting my fuel in the truck, the WMO blend cleaned the VO residue from the fuel system and some of it had the FPR plunger stuck open. I only had 16PSI of fuel pressure and ended up starving two sets of injectors and having several hang slightly open. I had bought a core set of AD injectors and planned to use them to buy some new ones. I ended up having to put them in the truck, to run them as long as I could.

Last Thursday, I bought and installed the new set of AD injectors and everything seemed great. Went camping and after around 200 miles, it started smoking again and getting worse.

I have 62PSI fuel pressure at the test port, close to the #1 injector. IPR at idle, is 8% and ICP at idle is 480. It really smokes bad at low RPMs and I have no idea what else to check, not to mention the serious lack of funds.

The fuel I'm running is about 95% diesel, so I know the oil isn't too thick in the fuel.

If anyone has any ideas I can try, please let me know..

What does the smoke smell like? Engine oil or diesel fuel? It'll give you a clue where to start looking.

My truck was once smoking like a bitch and I later discovered engine oil in the exhaust pipe tip.

Long story short, it was my turbo bearing & seal had gone bad. It was dumping oil out the turbine side of the turbo and out the exhaust pipe.

i would seriously doubt that your running waste motor oil cleaned up any polymerized veggie oil.

anything causing FPR plunger getting stuck is serious debris.

if you were running bioD then yeah, its an aggressive solvent and would clean crap up.

anyhow- like TG said, what does the smoke look like? smell like?

did you do the CCV mod running it to the tailpipe?

have you checked your oil? are you using oil?

I have a spare turbo for it and will look into it. The light gray smoke smells more like fuel.. It does not smell like engine oil.

The WMO blend I was using, when I got the truck, was 33% kerosene and 66% WMO. The kerosene and whatever may have been left of the detergents in the oil really cleaned things out. The CCV mod has been done and I may lose a half a pint of oil in 5,000 miles. Not bad, for a 304,000 mile motor!

Here's a little update...

Yesterday, I decided to try using the Evo tuner on the truck. I've had the truck tuned for towing and that's when it started smoking. I then tried it on the race tune and it still smoked. It smoked worse, when I put it back to stock.

When I got off work yesterday, I changed the tune to the Evo's extreme tune. I've only tried it once before, and didn't like the EGT spiking like it did.

Anyway... Once I was done tuning it, I left. The truck would roll coal at the drop of a hat! I didn't even need much throttle. I must have left a cloud of thick black smoke for at least a half a mile. Once that was over with, the truck stopped smoking completely. I could make it roll coal if I wanted to, but I was enjoying it not smoking for a change. I put 36 miles on it, coming home from work yesterday and another 75 miles today. That's about 110 miles, smoke free. It does still have a small bit of smoke at idle, but I'm used to that from both trucks anyway. It's nothing like the light gray clouds of smoke it was making!

If it starts it again, I'll report back.

Sound to me like it was babied to much and needs a really good 200 mile beat run to get the crap out of it. Short runs and long idles kill these motors.

Have you put in a 203 deg. thermostat? Helps the motor run better and a little hotter.

If you knew how I drive, you might think otherwise. As soon as I finished the injector install Thursday and got the test drive done, I pulled our 11,500lb fifth wheel 144 miles to go camping. It was on the return trip, that it started smoking again.

Just out of curiosity, could the AD injectors in an e99 cause the smoke?

ccv mod to the open air will produce smoke. and if you routed it to the exhaust, it will pour out the tailpipe.

who knows what kind of smoke is created by burning the waste motor oil blend in terms of color and toxicity.

both are polluting the environment. why do you think that they say not to use a waste oil burner near habitable dwellings?

pollution dilution is not an acceptable manner of prevention. then again, considering that you are in West Virginia, what is a little more environmental pollution after the coal companies raped the landscape?

where do you think all the wear metals that are in the waste motor oil are going? all the chemical additives? things like chrome, lead, molybdenum, vanadium, just a few that come to mind. those are not things you put in your morning coffee.

what about the solids in suspension like the soot and metal particles? where do you think those go?

ccv basically dumps all the blow by oil vapors onto the ground. you would not willingly pour used motor oil straight out of the truck into a storm drain or over your well?

I bet you drive it like you stole it.

Use my testing method. Beat it like it owes you money. Any hidden problems will be found.
