V10 Rattle
I have a 2000 f250 with a v10. It has a loud rattle sound. Its louder at start up but less after it warms up. The ford dealer hasn't looked at it yet but when i described it to them they think it could be the chain tensioners. They will look at it next monday. The service manager said that if it is the tensioners it would be at least $2400.00. Does this sound right? Seems like a lot . Has anybody else had there's replaced.

Check the exhaust studs first.
BUT - that does sound like a hell of a lot for taking off the timing cover and replacing the tensioners and/or timing chain. And guides if they need it.
Wonder if they are going to pull the cab off the chassis to do it?

I will check the exhaust studs tonight. It sounded like a lot for that job but I didn't know for sure. This same dealer charged me 280.00 labor to install a fuel pump on my wife's five hundred and it has an access panel under the back seat. Only problem is that they seem to be the only ones that know what their doing around here. Are these chain tensioners really that common of a problem on the V10's? I change my oil every 3000 miles. I have been using Napa Full Synthetic 5-30. I only have 110,000 miles on it.

One of the many heat shields maybe loose on the stock exhaust system perhaps?
Some have reported rattle-like sounds from spark plugs that have worked their way loose, and are primed for ejection. Maybe this could be it?
I'm just kinda thinking out loud...

Thanks for the replies. Its been raining for 2 days so I haven't gotten back to it. I replaced the spark plugs so I know that's not it. I will hopefully get under there today to listen more. I checked the exhaust studs last summer and they were fine but I'll defiantly check them again. Of coarse this would have to happen 2 weeks before we are going on a 5 day camping trip.

Doesn't sound like it's up top by the valve cover. Down low. The torque converter inspection plate could be it. It seems loudest where the block bolts up to the transmission. Maybe louder on the passenger side. Truckfella, what was the fix on yours. I hope its something simple. If its the crank or rods It will be the end of my favorite truck.

While you have the converter inspection plate off, make sure the torque converter is bolted to the flex plate tightly, and that the flex plate itself isn't cracked around the crank bolts....

They think it's internal. most likely a wrist pin. they suggested just drive it till it gives out. 4000.00 plus labor for a replacement. They didn't even put it on the hoist. just crawled under and listened for a couple minutes.

Please re-read Krewat's post #13 above. Loose TC or broken flex plate would make similar noises. Pull the sheet metal TC cover off the bottom of the trans and give it a very close inspection with a good flashlight, bump the motor over a few times to get a good look all around. Use the light to peek up between the TC and flex plate and look for cracks on the flex plate up near the crank attachment bolts.
