Argh, problems already.

Well, with 5800 miles on my 2010 Ford F250 with the 6.4 diesel, I’m taking it back to the dealer for warranty work tomorrow. Something is not right with the turbo chargers. The problem I experience only occurs when I don’t use the truck for two or three days. The truck starts perfectly, but I don’t have any turbo boost when I step on the accelerator. Instead a god awful noise comes screaming from the engine compartment. It sounds like a gasoline engine redlining. It is very unnerving. Once I’ve driven the truck for a half mile to a mile, the problem clears up and everything functions normally again. I’ve never experienced this problem when I drive it every day.

I’m thinking the vains on the turbo charges get stuck temporarily, but then I’m not a mechanic so I don’t really know. I do want this problem resolved before Aug 8^th when we start our trip to the Tetons and Yellowstone.

Hope they can get it fixed in short order for you Richard.

A trip to N.W. Wyoming sounds great! Even though I'm often in Wyoming, I've never gotten to the Tetons. Someday, I'll make it.

There is a TSB out on the turbos, had mine replaced at about 12 thousand, bearings rusted and seized made that same terrible noise

Vol Fire Department near here has a F-250 Brush Truck that has had a Turbo changed out twice because of rust. They were told to start it up at least every other day.

I am sure this does not pertain to Richard's problem since his truck is so new and has low mileage but I thought I would mention it for those who have diesels. I read a while back that you should leave a diesel run a few minutes after hauling a heavy load. Oil in the turbo is at a very high temperature and if not cooled down it will start to evaporate ( I believe term was Cokes up )and build up deposits in the turbo. This can lead to premature turbo failure. The article stated that you should leave engine run a minimum of two minutes prior to shutting down. Typically when I arrive at a campground it is not an issue since I leave the truck run while chocking the wheels and putting landing gear down. When we stop at rest areas or when we arrive home I always leave truck idle for two to five minutes.

The rule of thumb is wait to shut down the engine until the turbo temp is around 300-350°F. After a long hard run it could take 5 minutes, but for normal driving it takes about 30 seconds. In the winter it drops fast. I've done this for 10 years with no turbo issues to date. I just rolled over 102k.

Well, the dealer couldn't find anything wrong with my truck. They even called Ford for guidance. I was hoping the computer would throw a code but it didn't.
We mutually agreed that they should try to duplicate problem. They are going to keep the truck on their lot for the next three days and then drive it. I'm hoping the problem shows up when they take it our for a spin.

Just a suggestion, but it could be your radiator fan. I remember someone telling me about a similar sound and all the time they spent trying to get it repaired. An independent mechanic shop told him that his fan had a "clutch" that automatically adjusted how fast it would spin. Sometimes it would engage fully and he said the noise was scary, just like you indicated a gas engine red lining. Ask your dealer about this and post back here please. Could save a lot of headaches if it happens to someone else.

I have a timer that can be set to shut my engine down aftera specific time. I set the timer, and remove the keys. If someone breaks in and tries to take the truck (since they hear the engine running), the engine shuts down when the brake pedal is depressed the first time.

My new 2011 6.7L Power Stroke comes from Ford with a shut down option.

Richard, I was going to suggest your intercooler boots, but that would not be intermittent. Sorry, I know next to nothing about the 6.4.

For those with a 7.3 or 6.0; if your boot from your turbo pops off, it will make a horrendous noise and your truck will not have enough power to get out of the driveway. The Ford dealer left a clamp loose on my 6.0 one time and I got about 1/4 mile from the shop before the boot blew off; I thought I has going to have to call a tow truck.

They leave the clamp loose on purpose, so the Chevy's and Dodge can keep up...

NICE!!!!

When are you getting it? Or do you already have it and haven't updated you sig yet...

Remember, some pictures too....PLEASE!!!

Just came from a trip across Pa Rt 30 pulling the Cat stayed at Ye Old Mill Campground. I finally got to hear what the clutch fan sounds like when it engages completely with the engine at high rpm's, thought I was now the proud owner of a ford with a jet engine. You know its loud when DW asks what the loud noise is and is everything ok? The noise is much worse then when my turbo went up. BobnPi is right on in his post, it is kinda scary at first. All seemed well after it kicked out, truck ran fine.

When you start your diesel truck let it run for about 2 min before you put it in gear. When you get to your point to stop and have not pulled anything with it let it idle for 2 min before you shut it down so that oil will have a chance to cool. After you been on the road with the camper always let it idle for 5 min before you shut it down to let the oil cool the turbo down. On 6.0 Ford a friend just had his replace for the 4 time and dealer told him he needs to run the truck every other day to avoid any problems with the turbos. They will rust the fan blades or bearnings as said above. Driven diesel for over 30 years and never had to replace a turbo yet. Thank god.

I think a rusted turbo has a lot to do with humidity. Here on the left coast, I have not seen a rusted turbo. Most of our problems with the turbo is do to running it out of oil, like shutting the engine off before the turbo stops spinning, causing the bearings to wear.

Well, the Ford dealer couldn't duplicate the problem so I'm not going to worry about it for now. Perhaps it was the clutch fan but I wouldn't think it would make that noise after just being started. Hopefully I won't have any problems on our trip to Wyoming. We're leaving Saturday morning.

Hmm, my 2006 6.0 sits in the garage for up to a month at a time without being started, still have the original turbo too...

Richard,

On hot days with my AC going at startup, my truck will start with the fan clutch engaged. It shuts off after I get going, but I've never noticed a loss in power. Sounds like a fan moving lots of air. You might try an experiment with the AC switched off at startup and see if you notice a difference.

Also, I'm not sure if the fan clutch is electromechanical or simple a mechanical clutch in the 6.4L.
