2013 6.7 liter white smoke

[d41pw54]

White smoke from exhaust when I come to stop sign. Also it does not happen until 192 degree coolant temp. Either an injector failing or ??

Smoke or steam? Does it linger or disappear rather quickly? White smoke would be oil, black smoke would be fuel. Steam would be head gasket.

Only white smoke when coolant temp reaches 193 degrees, sometimes it lingers, other times it dissipates.

Easy check sometimes for head gasket is get it to operating temp and watch for bubbles in the overflow tank. Is it losing coolant?

Nope on both. Nothing in oil and nothing in coolant. I have heard this could be the start of an injector failure. PS, I do thank you for your replies. All info is a big help.

This is my first Ram, and a search didn't turn up any easy results. Did the '13 have an aftertreatment? If yes, does yours still have one? Sometimes if the DEF system is injecting too much that can cause white/grey smoke also.

It has been deleted. No DEF. Know nothing about aftertreatments? It has 200,000 miles on it.

Gotcha. Looks like you may be right about the faulty injectors. The unburnt fuel smokes white/grey too.

Get a whiff of it next time you can. Pull off to a parking lot or wherever, see if it burns your eyes would like raw fuel or sweet smell like coolant.

2013 Dodge 6.7, bought used, trans failed a year ago, had it rebuilt. It was deleted when new, and chipped. The deleter/chipper took the brand new turbo and exhaust manifold off, replaced it with a Gen II turbo and manifold. Not sure why (do know people are doing this for more power) however I would have stopped after the delete and chip. Now I am finding out my problem could be the older style turbo is failing. I appreciate Darmicher's replies, am still open to more from him and anyone else. My next move is to hopefully obtain a rebuilt 6.7 turbo and manifold and put it back original.

Unlikely the turbo as you would have black smoke while accelerating/ driving. Injectors would hase all the time usually more when cold not just when the truck hits OP temp…. I would pick up some combustion gas test strips and test the coolant, to me it is either the headgasket or if it still has the egr cooler intact it may be cracked and allowing it to burn coolant

Yup. Completely forgot about the EGR cooler.

not sure if it has an egr cooler on it, Looked online and do not see one on this truck. Engine has been deleted. I assume it is or should be on the turbo side of engine above exhaust manifold? Where can I get the combustion gas test strips?
