White smoke only when engine is cold

I have a 2006 5.9 cummins.. I just replaced all 6 injectors today and The truck puffs white smoke when the engine is cold.. but once it warms up in about 10 minutes , the white smoke goes away.. I live in Florida so I don’t think that’s normal.. I don’t have my heater grid since I have an after market intake.. any ideas what could it be?

Itís compression. One or more of your cylinders have worn or cracked rings, possibly a valve issue (lash way out or valve not seating). When the engine gets warm enough and metal expands, compression increases and you can squeeze the air in the cylinder enough to generate enough temperature to immediately burn all the fuel injected into cylinder.

You probably didnít want to hear that. I have well over $100,000.00 into my 2015 and only 40,000 miles, I have the same issue but my problem may be from bent connecting rods from too much power.

I just bought a whole set of factory new Bosch injectors and installed myself. Didnít change a thing, I am literally refinancing my house to pay off $50,000.00 of credit card debt mostly from truck and have some cash to replace rods/pistons, hone cylinders or bore over, maybe just get a fully built performance engine if it looks bad.

Iím 6í4Ē and my truck is my Sports Car/Hotrod, since I canít fit in one, but I had no idea what it was going to cost me and I donít even have my compounds yet.

Post your truck details and mods if you want a more detailed answer.

Good luck, Tom J.

Did you go reman injectors or brand new Bosch units?

If you went with reman my money is on the injectors. Very common.

Bingo.

I will add, though, that BBI remans have a good reputation.

R12 in the summer, Webasto in the winter, and cassette tapes all year.

FWIW, a lot of BS with "new" injectors should make sure you got what you paid for

If you are sure got real brand new Bosch injectors, properly installed.
next i would check for any codes ECM controls fuel, monitor/check rail pressure demanded vs actual, when issue is occurring.

are they oversize or stock? I have BBI stage 2 injectors and when it is cold out mine make a white haze when it is cold and when it warms up it is fine. It really is smokey when it gets below 50 degrees. I also have a fairly new rebuilt engine as well so i know I don't have any cracked rings and I have no blowby either.

Not too long ago I received a PM about a set of injectors I bought from Injectors Direct. The PM claimed ID was selling cheap Chinese injectors as brand new Bosch. Said there was proof but he has not answered the two PMs I sent asking for details. I think it was a load of crap accusation. Iíve got nearly 100,000 on my ID injectors and could not be happier.

OP, it might behoove you to confirm what your injectors are simply because of the stories floating around out there.

Did your truck smoke before you installed the new injectors? If it did I would suspect compression. If not, Iíd suspect the injectors.

What are ALL the numbers on the top of the "new" Bosch injectors you installed?

Are they stock flow or aftermarket high flow rate nozzles?

Same jackA$$ PM'd me about Injectors Direct also. The injectors I bought from them are legit, and I have put a ton of miles on them, no problem. These guys are awesome to work with.

I wrote an email to ID to let them know they got a guy pulling this crap. They just called me just a little bit later to discuss it. The guy is full of it. He is one of those sue-happy subhumans. If you search his name on the interwebs, he is all over it. I think he spends the majority of his life in court. Probably makes good money at it too!

If it didn't do it before, and it does now, it has to be the injectors, or possibly install. If it did the same thing before, I would think it is a compression issue.

He’s all over the net but not for what you mentioned. He’s all over the 10th circuit court docket for a conspiracy to distribute Oxycodone conviction!
