Seems worse if the engine brake was used. Detroit have checked the engine and say nothing is wrong but can,t tell me why it is doing it. Perform the following to determine if injector setting repair resolved excessive white smoke : ‪ Start and run the engine. Run the engine at idle with a no-load for approximately minutes, allowing the engine coolant to reach normal operating range. Visually inspect exhaust for excessive white smok e. I have a DDwith white smoke coming out of the exhaust during regeneration.

I have already replaced injectors and it does not waste antifreeze freon. I would like to know if anyone can tell me What else might be the cause or what else could it possibly be. I appreciate all suggestions, thank you in advance. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time.

Too many variables here. Does it blow white smoke all the time or only at idle? I recommend checking you oil to see if it looks milky.

At a minimum you will be changing injector o-rings, but with that much antifreeze it could be head gasket, leaking in the cylinder wall, too many things can cause that. Freightliner blowing white smoke from exhaust. White Smoke Indicates a Faulty Fuel SysteTime for a Fuel Injector Service.

Blowing white smoke is a red flag for your diesel engine, yet we see this happen all the time to our customers. Got behind a road tractor tonight that pulled out very slow in front of me. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. You can easily find out whether the smoke coming from oil cap is a fatal sign or not.

Start the engine and let the car to idle for some time. Loosen the oil cap slowly and then remove it completely. If there is only a small amount of fume blowing out of the motor, you have nothing to worry about.

Chances are the problem is internal injector leakage caused by seal failure. I changed my pcv valve and the problem went away. I assume that it was caused by the pcv being clogged.

So, the normal crankcase fumes would build up and the gases could only escape through the breather. Sorry for such a long post, just trying to answer all the questions I imagine may come up after I re-read my post before posting.
