I need some help.

My turbo started to leak oil on the outside. My mechanic was out having surgery and I took it to the local Ford shop. The Ford shop put in a new stock turbo and changed out the cam shaft sensor, which was a factory recall. It now smokes white smoke while driving. I took it back and they said to drive it and the oil that may have spilt into the exhaust would burn out in 30 to 50 miles. Still smoking, so I went back again and showed them. They then said that the turbo has a 500 mile break in period and to put 500 miles on it to see if it helps. I don't want to hurt the truck. I have put 100 miles on it and it still smokes. It does not smoke when you start it or let it idle. I can not see any smoke at road speed or for a while after I slow down and cruise around at in town speed, but after a while of in town driving with low EGT's or after letting it idle and the engine is warmed up it blows white (maybe blueish) smoke. The more you push the go peddle the more smoke until the EGT's get high then it goes away. I just want them to fix it right. It didn't smoke before. What can I tell them? If ya'll have any ideas please let me know.

On another note the reading and topics here are great. Ya'll have already helped so much, and been interesting to read.

 

Are you sure that the turbo was leaking on the outside?If so where apox? If you replaced the turbo because it failed (like a broken turbo shaft) then this will fill the air to air with oil.This is not good because the truck engine will run away on you.Seen this happen to many times. White smoke is raw fuel unburned. Is the engine have a miss to it?

 

Possable there is oil in the exhaust pipe that wont burn out till you load it down from the original turbo failure. If they said go out and drive it hard then take one of there techs with you down the road.

 

This has got to be oil. There should be no way you blow white smoke when the engine is warm as this is usually associated with unburned raw fuel in a cold engine or a coolant leak with a blown head gasket. So if neither of this is the case, I would have to say that is oil burning. Make sure the smoke is not blue. Unburned fuel in a healthy diesel is black.

 

Losing an injector tip will put out white smoke on a hot engine. If he had a blown head gasket or injector copper he would have problem keeping water in it. like i said it will run on oil but not for long.

 

He would have a rough running engine if he had a broken tip. I don't remember the last time I read about a runaway engine here.

 

I have seen a runaway on oil caused by a tech that didnt remove the air to air when the turbo failed. You can dump alot of oil into the air/air.Some techs tell the customer to drive it out.Thats wrong way to do it.

 

Not sure where it was leaking exactly. It leaked oil off of the turbo after the engine ws running for a minute or so. A friend that is a mechanic looked at it and told me the turbo was leaking oil, but we couldn't exactly see were. He said he did not want to mess with a turbo. Ford shop said yes turbo leaking. I will ask the mechanic next time I am in.
What is the air to air and is there a way to check to see if it has oil in it?

The engine does not have a miss to it, but it does seem to have a slight undulating sound after it has been idleing. I mean that after idleing a while when the louder air sound (like a little jet, not an expert on sound titles, have 4" exhaust) the engine seems to fluctuate a little, but non of the guages reveal anything. Might just be me looking for something.

thanks for the advice

 

The smoke looks white to me. I drove the truck to the Ford house after finding the leak (about 6 miles) and there was no noticable smoke at all. The truck does blow a little black smoke, (before and after the shop) when I realy get into it.
