HELP* Okay fellas, time to get some real advice. 2002 f250 336xxx
I have a majoor blue smoke issue, could be coming from a few spots, sometimes kind of white smoke, mostly always very blue. I KNOW there is 1 glowplug out on my passenger bank, that is getting fixed when the rain quits, also has been this way for a while and causes a good amount of smoke on startup, that part is understandable. Recently i have been getting blue smoke at idle at stop lights, when i accelerate away i get big puffs of bluish white smoke, but only sometimes, not consistently No smoke at cruising speeds. Sometimes after an hr drive and i stop, absolutely no smoke for 5 mins of idle, then it comes back slowly, and sometimes after the same hr drive, itll be smoking. I'm going to get going on a compression test as soon as i find the adapter to fit. REALLY hoping my motor doesnt need to be rebuilt. Hopefully some one can shed some light. Not really sure what im looking for when inspecting injectors. I'm going to buy the O-ring kit today, maybe turbo rebuild kit too? Dont wanna just throw parts at this thing. could it be ebpv stuck open, it is pretty cold here in north idaho?

CODES
p0029
p1100
u2212
p1316
p0475
p1280

 

I do have a bluetooth Obd2 device as well. So i have access to data from the truck just am not completely sure what im looking for.

 

MORE INFO** Just pulled the turbo intake to inspect for dusting wear oil ect.. There is oil in the turbo but minimal, i believe it is because of the truck needing CCV mod. Appears to be pulling oil from the doghouse. ZERO play in and out, very little play up and down, under 1/16".
Pulled the fuel filter to inspect for black walls indicating o rings, no black AT ALL just the off white color a fuel filter appears after 2800 miles.

HELP

 

Sounds like very tired original injectors.

 

A few things...

• The smoke could a few things, but since you have DTC's logged, you should start with those.
• Have you tried clearing the DTC's and seeing what comes back after a short drive cycle?
• A small amount of oil in the intake tube and CAC system is normal.
• Since you have access to an OBDII adapter, but are unfamiliar with what to look at and/or for, check out the links below. Pay special attention to the last one, the Q&A.

Unrelated to the post, we have family in ID from Boise, to Challis and up to Orofino and get out there about once a year. We very much prefer the Challis and Orofino area, but there is no place like home here in north GA.

 

Okay, i could definitely see that with out a doubt, why all the blue smoke now? bad o rings? i dont see any other indication visually, would ipc psi of fuel help to determine that? hmm so many questions. is there any affordable fix, ie shims rebuild ect

 

After clearing and going for a short drive, p1000 and p1316 remain, p1316 has been around since ive owned the pick up, over a year and a half.

 

Ipr duty cycle % at idle after idling for 10 mins haven't revved the truck at all. jumping between 5.8-6.27%

 

What program are you using to read this parameter? That number does not make sense. Assuming that is IPR%, it's reading low.

Recommend capturing a log with FORScan Lite and your OBDII dongle with all of the parameters listed in the Q&A file. Post a 30 second idle file and a several minute normal drive file. Let's see how ICP, IPR%, FUELPW, etc behave.

That P1316 has some codes behind it. Run the buzz test to extract those. FORScan Lite calls it KOEO Injector Electrical self test. It might be time for some UVC harnesses, or at least the 50 cent mod.

I would suspect tired injectors, but good to eliminate the causes of these codes first.

Have you had the ICP sensor replaced since you've had it? Is it a motorcraft part? Any oil in the electrical connector to it? How does the pigtail look?

 

Should have been more specific, ipr duty cycle% was jumping between those 5.8% then to 6.27% back and forth at idle, relatively cold still. I use car scanner pro, and car gauge pro. car scanner pro has been very reliable for me in the past. car gauge pro will do self tests.
recently did ICP and pigtail with motorcraft parts and solder connection on the pigtail
I have done UVCH and harnesses on both sides
I will work on getting some files for upload, i have quite a few but none from the last week.
things i would like to add, she only blows smoke when the SES light is ON. The SES is on intermittently and is almost always throwing p1316 when is comes on, sometimes other codes. When there is no light the truck runs pretty much perfectly besides now slight blue smoke at idle.
also ses pretty much only comes on between 0-1600 rpms, anything above that, she loves it and never has a light.
I know this is quite a bit of info and im not putting it into the best format. apologies. Thanks for the quick response!

 

I am also unsure of how to upload the file.

 

I'm happy you have data. You're doing just fine getting us the info. We'll do what we can to help.

Normal cold idle IPR% is 12-17%, and heads down to 9-12% when warmed up, typically. If your IPR is really at 5.8-6.27%, it's not providing enough oil pressure - that would create white/blue smoke I would think, from fuel that is not atomized well. Tired injectors will compound this issue.

What is the ICP sensor reporting at idle? Should be around 700psi cold, 475-500 warmed up.

This is probably a long shot, given you have a relatively new motorcraft ICP/pigtail in there, but you could try unplugging the ICP sensor and try your cold start and daily drive - see if it still smokes, or at least smokes much less. Commanded IPR% should go to the normal numbers above, and you might see an improvement - pointing to a bad/biased ICP sensor and/or pigtail.

 

To upload a file, click the picture icon next to the smiley face when you are composing a post, and it will give you a window where you can attach your file. I think the size limit is 5MB.

 

confirmed at idle my pickup, ipr duty cycle% stays inbetween 5% lowest 7% Highest, ICP is right at about 475 all the time at idle.

 

The low IPR % might be a wonky conversion by the app. Can you read the volts?

Try Forscan, more reliable and familiar here.

The P1316 is what I'd focus on. Typically that code is no bueno.
