Po216, blue smoke from exhaust

This is what I did on my truck been like that for years now

A similar issue has happened to me. The 1999 Dodge Ram 2500 I had sold to my brother is back with me. My brother was passing through to visit after his work finished in FL. When he got here he told me he had a P0216 Code showing. We drove it about 20 miles and it would do fine and then loose power but a downshift would bring it back. He was headed for a Pipeline job as an inspector so he asked me if I could sell it and get my money out of it to pay off the balance owed me. He went down to the GMC dealer and bought a Duramax. A couple of days later I went out and checked the codes and the P0216 was showing up. The tank was 3/4s full so I put a quart of 2-Stroke in the fuel. He had told me when he left Crystal River FL he added 2 cans of Seafoam to the tank. Don't know if this was a mistake or not, some say never use Seafoam in a diesel????????? I have never used it but from what I have read it's mostly oil based. The 99 starts up great and revs fine even when cold. So I took it out and drove the wheels off of it. It moved really good but it poured black smoke out in every gear. When I owned it would haze a little black smoke in 2nd and 3rd at acceleration because of the Blue Chip Special X mechanically advanced VP44. Any way, when I got back the code was gone. So I went back and did the same routine again. Still no code. My brother is not a mechanic so when he heard a noise or thought something needed to be changed it was changed. Still one issue remains and that is the Raptor lift pump. It constantly changes pressure and it is the second one on it during the 45,000 miles it was driven. The Tee from the return fuel line in the head to the tank was replaced because it leaked, no leaks now in the fuel any where. When I bought it and the lift pump failed and the VP44 failed I had to drop the tank to remove the electric motor. I just saw a video where there is a check valve in the suction side of a Tee that needs to be removed to insure no starvation to the Raptor and VP44. I've got some help lined up to remove the bed so I can get to the fuel module. I have considered getting a G&R sump for the bottom of the tank with a supply side and return side to see if this will help maintain constant fuel pressure. My brother has used a lot of different fuel additives which I think could or were damaging to the lubrication of the VP44. It took a long time to convince him to just use 2-Stroke. I don't know if the code is coming back or if this band aid has fixed or helped the VP44 to last a little longer but time will tell. The 99 looks new compared to the 98 I drive now. Steven, I hope you get it figured out.

I have to thank you all for the invaluable help you have given me. The truck has a new Vp44 now and it runs way better than it everhas before. I just gotta get a return label printed to return my core vp44. Thank you @Mopar1973Man, @JAG1, and @trreed for the magnificent adivce. The quadzilla is awesome, I got a BD Stealth cover for it and I have now discovered the next weak link, the clutch?. Don't worry, it still drives great, just gotta keep the power level under 6.

Simple solution. Build a tune that has a less aggressive fuel curve and then make it 7 levels. This way you can float on level 4 which would be 25% wiretap. Then I would set the wiretap for only 1200us pulse. You could just drop to level 3 and be strictly CANBus fuel and not even worry about it.
