You've likely lost the number 3 injector. Unplug it and see if the smoke stops.

 

What do I unplug and which is #3 cylinder?

 

Got the plug pulled and it’s still smoking and running the same. No longer have the p0269 but only p0267 injector circuit lo cylinder 2 which I didn’t have before I’m guessing from unplugging it

 

The pic shows the location of #3. the connector is on the upper side of the valve cover. It has a clip that holds it in place. I can't find a decent pic of it in place.

About 3:20 of this video shows you how to unplug it,

 

Driving with it unplugged seems to be a little better a little less smoke. Slight stutter when driving but shakes when stopped. Days leading up to today it did have a very slight miss but no cel. My Silverado did the same so I thought it was normal

 

Yeah, p0267 is still #3 and it's because it's unplugged. If it's still smoking, I'd guess cracked tip. I probably wouldn't drive it much like it is due to the possibility of a hydrolock. It's still going to run rough because you're down one cylinder.

 

This is a horrible time for this to happen. Supposed to be closing on my first home in 2 weeks. Wonder how much this will break my wallet

 

A reman injector can be had for around $170. They now have brand new injectors available for about $240. New ones haven't been available for a while now, but have recently been put back on the market.

I assume you have stock injectors.

 

Yea I don’t mind paying that for a new injector. I just pray that it is indeed just an injector and not the whole cylinder.

 

I think you probably caught it in time, but like I said you don't want to keep driving it until you get the injector replaced.

 

Yea I thought about driving it to the dealer down the road but I’m just going to probably call a tow truck and get an Uber home and to work for the rest of the week.

 

Just got a call from the dealer and they are saying #1,#3,#4 cylinders have low compressions. Cylinder 1-11%, cylinder 3-12%, cylinder 4-15%

 

Out of my expertise, but I would think you would have gotten more than just a #3 contribution code if three cylinders were down. Did you have an FICM problem recently? If all three injectors did go it could have washed the cylinders and be part of the compression problem. I think I'd want a static compression test run before I went any further.
@LoxDiesel @toren302 @nighthawk285 Thoughts?

I agree with Dex to a point that if you had compression issues you'd likely see more codes, but there are other things that come up when doing a compression test that need to be known to determine the health of the engine.

Why did they do a compression test in the first place, that's an odd jump? Did they squirt oil in the hole and re-test and if so, did the number change? Was the engine cold (I'm guessing so)? %s are great, but what is/was the PSI? If the majority are around 350-400psi and at worst, cyl. 4 is at 300psi......yeah that's 15%, but 300psi is still fairly decent....it's not optimal, but it's still very runnable. What's the mileage on the truck? Remember, that as you were driving this around with the injector unplugged and during the times you saw white smoke, you weren't just dumping raw fuel out the exhaust....you were getting some in your oil too. Oil thinned out by fuel isn't going to give a fair reading in a compression test IMO.

I wonder if they meant to say that they did a CONTRIBUTION test and the service writer mis-communicated that....? This would be more in-line on diagnosing a downed injector(s) than going right into a compression test. If so......those sways are normal-ish, since the known bad cylinder is going to bring the other ones down a little bit too.

Honestly, if it were me, I would just have the #3 injector swapped out, have an oil change done and be on my merry way. Like you said, you didn't have problems until the injector started acting up. So fix the issue you went there for. Once those are done if you're still worried about it, have another compression test done, or at the least ask to see a picture of the power balance test once the truck is running correctly again.

No ficm issues, always at 47.5- 48v And never drops. It’s just weird because I only have this one code and before this the truck ran fine other than long crank when cold. It never skipped when cranking. All of this really sucks because I bought the truck in January of this year, Glow plug control module went out, ac compressor seized and I changed every single part in the ac system due to contamination. Heater stopped working, 4x4 doesn’t work. Fixed the rear sliding window. Just so much 2 weeks before closing on my first house

 

Not 100% why they did a compression test. The note I left with the truck was to troubleshoot injector #3. I’m unsure what type of compression test they did, I called back and left a message so when they call back I’ll be able to ask that question. It has 210,000 miles and I’ve personally only put 3700 of those miles on the truck. It’s worth a shot to just replace that one injector, I guess I’m just waiting on a return phone call from them and I’ll update you guys and make my decision tomorrow.

 

I had assumed earlier that they had done a "relative compression test" using Ford's IDS software since they gave you the numbers in percentages rather than actual PSI values on each cylinder. #3 and #4 fire in succession and #1 is 180° out of that order. So the relative compression test may be swayed as @nighthawk285 mentioned.

 

Think I should just make the call to just replace the injector?

 

Just spoke with the service advisor and she says they can’t just replace the injector. Stating that they don’t do half way work. I was rushed off of the phone and she said the only option with them would be installing a new engine. Didn’t try to answer any of my questions. I told her to have my keys and a summary of all the tests performed ready for when I come and get my truck. She quoted me $18,000 on a replacement engine lol.

 

LOL, some dealerships are just that way.

 

I don’t see the issue when they explained it might not fix the problem and I agreed that it might not. There shouldn’t be any push back from their side because I acknowledged that’s what I wanted to do regardless.

 

Yeah......I figured that's exactly where the conversation was going to head. Give it the radiator cap treatment and call it a day.

Where are you located at Druben? There might be some good shops that some folks can recommend.

 

Baton Rouge, Louisiana

 

There's a BulletProof Diesel Preferred installer there

Tri-Care Automotive
13873 Airline Hwy
Baton Rouge, LA 70817

225-751-9361

might give them a call.

Reviews look good online too....

I actually called there this morning and they quoted me $660 to install that injector. That’s where I was going to get the truck towed to

 

That's not too bad for 3 hours book labor and a stick at retail. Only other suggestion I would have would be to let them know what's been done and said/tested, and let them re-diagnose from there.
