Ford Diesel engine blows off the intake rubber intake hoses, blue in color with 7.0 Liter. If you have a problem with this engine as stated above there is an updated hose for the intake tubes also remove the intake pipe on the turbo side of the turbo remove the 10MM bolt that holds the metal tube on to the block and remove the clamp on the turbo, remove tube. Next look at the turbo shaft inside do you see oil in the turbo? If no then grasp the turbo shaft and try moving it up or down and in and out. Any Movement The turbo needs to be rebuilt before replacing the Turbo hoses. If there is oil in the turbo then it needs to be rebuilt so stop at this time and decide what you want to do with it. The turbo also has a flapper valve inside the turbo that goes bad at about 100,000 this is the boost waste gate and boost flapper valve, it is an internal gate unlike the mechanical ones on most turbo. If you have low power check the boost pressure with your boost gauge if you have less than 12 pounds of boost then it's time to look at the turbo. Of the Turbo I have rebuilt I have increased fuel mileage by 30 percent. If you want the details of how to gain the extra mileage post a comment to me or ask this question and I will get back to you for the procedure.
Most oil leaks on this engine occur in the valley of the engine at the back of the oil pump. If you look directly down into the center of the engine infront of the turbo you will see the back of the pump and the potential leaks at the plugs on the pump and the output lines to the heads.
Does any one have a idea a friend here has changed ecm, inj, fuel pump checked conector at fire wall ,fuel and has a short wrecker tow f450 99 and will be going down the road and he says the thing just loses all power and kind of just won't do over 15 to 20mph and lets it sit and he says it will do it again. I am not sure how long it takes but since I don't work on diesels I figured I would have the experts that do if anyone knows it's you guys any help he is in Charlotte NC I can put you with this guy he has had it to all the parts changers and no luck Thanks Mark 704 492 1647
There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.
MY 2001 7.3 was leaking the same way. The dealer said the o'rings under the pedestal were leaking. I had the dealer replace the o'rings. By the time I got home, it was leaking again. Called the service department and told the manager,and they put on a new pedestal and o'rings. They only charged me half price for the pedestal and no labor. That did stop the leaks.
