6.9I smoking
My wife was following me the other day and said that there was constant smoke coming out of the exhaust. She stated at idle and cruising speeds it was white and when I would accelerate, it would turn a little black, but it there was always some sort of smoke coming out. It's not bad enough that I can see it through my mirrors while driving, but she saw it while following me. The motor is in a 86 F250. I'm actually getting ready to pull the engine to put in my other truck, but was wondering what it could be, or if it is normal for these motors. I'm planning on repairing some of the oil leaks while the motor is out. And if need be I can perform other repairs while its out, as long as it's not too expensive. I cannot afford a full rebuild at this time. Thanks for your help.

more details, how many miles, how old is the IP and injectors? when was last time u serviced the CDR valve? air cleaner?
|
There are about 163000 on the truck. As far as I'm aware, the IP and injectors are origanal. The air filter was just replaced.
|
i would say the injectors are shot. ip possibly is going out also. both these parts normally only last 100000 miles or so. maybe a little longer. get some good brand(delphi) injectors BB coded.
ip pump see if it can be rebuilt locally. try and find a diesel pump shop. do not get anything from pesocola diesel. |
in jectors for these 6.9's are only about $35 a peice, i need to put some in my 84 6.9.
|
do not get them from a parts store. go to an injection shop and buy them from there have them pressure matched also. motor will run alot smoother
|
When the injectors get older they can cause the timing to change as well since the springs are weaker and will pop at different times than when they were new. Your timing could be off or you could have an injector leaking fuel.

hey i got a 19 7.3 the same with these too? i get like a blueish black smoke when parked and stomp it. i also run the truck on used veggie oil maybe just due to running the used oil don't know mabe something else but any thoughts?
|
what the heck is a CRD valve??
|
it is a valve on the back of the intake that does almost the same thing as a pcv on a gasser.
