November 16, 2005Funny you should mention that. I drive an Econoline V-10 vanpool van and it does the same thing, and the same as yours, only at certain RPM's. We've told the van company about it but it never seems to get fixed when it's in for maintenance. I'll keep an eye on this thread and hopefully someone knows what it is.
November 16, 2005Interesting does this by chance happen at around 75-80+ MPH?
about 3-4k RPM's
My truck has the same dam thing and I have replaced so many things trying to figure it out. It is somehow related to the exhaust and I have been told that it is a harmonic resonation inside the exhaust. Ford has a black dampener that clamps on the exhaust pipe so I went ahead and purchased one and it did not help.
November 16, 2005i have a anks cat back, and im almost ready to get headers and y pipe just to see if itll work....bot thats alot of $$ if it doesnt. it happens at slower speeds on mine
November 17, 2005I don't drive the van over 70 but it happens mostly around 35-45 mph, and only for short periods of time, not all the time. Very strange. Sounds like something in the exhaust, perhaps the cat.
November 21, 2005I had this on my V10. I found it to be the heat shield on the exhaust pipe close to the oil filter. One of the welds had separated. Just a thought.
November 26, 2005My 02' did it our military GSA's with V-10s do it and the V-10 I have now does it. I have had brand new rentals do it also, I think it's just one of those things that never got worked out from the drawing board. Thought it had something to do with cast manifolds and if you changed to headers that there wouldn't be any noise. But that's my
December 2, 2005The cat is prolly rattling loose.
December 13, 2005I have a '99 f-250 and i have the same problem. I have read in one of my trucking mags that it is the factory Y pipe. The exhaust gets restricted right there under the cab. I read that Banks puts out A complete exhaust system with new Y pipe that blend together to get rid of the problem. I believe they called them Torgue Tubes! Im looking to install them in the near future for my self.
December 13, 2005^^That is very interesting because my noise seems to be coming from the area about where the Y pipe is located. My noise seems to show up if I start approaching 78MPH and get louder the faster i go. The weird thing is sometimes it doesn't do it and then sometimes it isn't as loud as others. So what you are saying about the Y pipe does make sense. Not sure why it would cause the type of noise it makes though.
December 15, 2005Richard,
Im looking at the pic of the stock Y-pipe on a '01 f-350 with a V-10. In my Trukin mag (july 2003) it says " the stock Y-pipe is not a good set up. - the exhaust pulses collide together under acceleration and cause a pinging noise that is both power robbing and very annoying." the pic shows how the y pipe is almost like a T so you have one side of exhaust being forced into an "intersection". I hope that you understand kinda what im talking about. If you want crawl under your cab and find the y pipe. I think that youll understand what im talking about Get back with me let me know
