Rebuilding the turbo would stop an oil leak if it was coming from the turbo seal and if the turbo bearings are shot then the seals could be leaking.

Leaks from the rings, valve guides etc would not be cured.

How much boost are you getting on the dash gauge? It should be around 25-30 psi when you push it.

These engines really like to be exercised and driving around the block is not good for them. After the engine gets warm you need to stand on the pedal every now and again to work the turbo.

 

I believe the bearings are about shot. The turbo still works but I don't want to drive it much until I get it fixed. I don't have a boost gauge or anything in it. I just got it from and old rancher. He used it good. Pulled his gooseneck trailer all lover the place. I mean it's been worked.

 

Yup, I forgot that the older ones didn't have a boost gauge. You should take the inlet duct off and make sure the impeller is not rubbing on the housing. If the bearings are shot you could be doing more damage and end up buying a new turbo.

A ScanGauge II is a worthwhile investment to tell what is going on. I'm not sure but you can probably read boost with it.

 

Are you burning oil out the exhaust or leaking oil, and if so, where?

 

Actually you should not be getting over 28 psi.

 

It's burning it. I was told that atleast but in not sure yet. I'll have to change the oil and keep an eye on it for a while. But yeah I'll take off that duct off and check that. Thanks a lot you guys. I'll check that out later today and let you guys know what it looks like and what I should do next

 

I agree, my stock 05 hasn't gone over 27 psi but bismic states that severe service is up to 30 psi. https://www.ford-trucks.com/forums/9...-pressure.html
Would that be with tuning?

 

I put that together a long time ago. The early year models were tuned (factory) to develop more boost than the later ones.

 

Hey Mark,

I have a question that I've had for a while but never needed to research.

Do the early 6.0's have a boost pressure transmitter that can be read by the Scangauge? I know they don't have the dash gauge but they would still need the boost signal for the PCM to calculate how much fuel to inject .

 

The MAP sensor value, minus the Barometric pressure is the boost.
