If a hose popped off it may be a vacuum line if it keeps popping off have it checked because it may be pressureizing the crank case. To much. Put the hose back on

This morning my truck was fine and running perfect. I shut it off for about an hour and when I left again I felt a miss and it started smoking when accelerating. When I reach speed its minimal smoke. But at slowest speeds and take off is when it happens. But this morning it ran perfect. I changed the oil put injected cleaner in it and changed the fuel filter. It's a powered role 6.0 diesel how do I replace the turbo?

I attached the procedure for replacing the turbo for you. Trust me, it is tight to get to everything. The first thing I would check is the turbo. Remove the inlet hose and look for signs of oil. You may have a failing turbo.

I have an 2002 f350 7.3L powerstroke, just out of the blue the turbo started getting hot even without a load behind the truck. I had a Superchip programmer but returned it to stock and the turbo still gets up to almost 1200 degrees if I pull out to pass a line of cars. Installed new air filter, fuel filter and had an oil change, right after I started noticing the problem. HELP!

Do you have a boost gauge? Your turbo heats up with exaust gas. If you have a wastegate stuck closed, your exaust is staying in the turbo longer, and creating this heat. If thats the case, your boost should be higher than normal.

Engine Performance problem
2002 Ford F-350 V8 Two Wheel Drive Automatic

While I was driving down the road I heard a pop then a whistling noise like a tire losing air but all tires checked out to be fine I can still hear the turbo whistling so it is still working but I do have loss of power. I dont have the power like I used to while pulling my 3 car trailer. I checked the 2 boots or pipes coming from the intercooler to the turbo and they are fine and I cant find a diagram on the computer anywhere for all the turbo hoses to check to see if I am missing any. Does anyone have any suggestions on what to do or what my problem could be, I was told I blew a turbo hose or boot.

Check the intercooler itself they did blow out check where the plastic goes to the side and you will see the rubber hanging out of the side, or eles check the 2 orange boots under the turbo.

Check the hoses from the turbo to the intercooler in the front. It is common for the clamps to loosen up and the hoses to come off. It sounds like a pig squealing when it leaks boost.

Roy

TURBOCHARGER LEAK TEST

Check for loose connections or damage to air intake hoses and tubes.

Air leaks at the compressor manifold, intake manifold hose, charge air cooler (CAC) or intake manifold can cause excessive smoke, loss of engine power or a noise condition.

Exhaust leaks at the exhaust manifolds or in the turbine housing will also cause loss of engine power and a noise condition.

Inspect turbocharger and components for loose connections or damage. Using a liquid soap on hose or tube connections will aid in leak detection.

Exhaust leaks can usually be detected audibly or visually by a discoloration caused by escaping hot exhaust gases.
