I have a 4.6L-2V Triton engine with 91,000 miles on it - 2000 model - I have never had any problems with the truck and I can honestly say...I LOVE IT!!!
I discovered that it had a low ticking noise and the sound of a chain rattling when the vehicle was moving.
Yes, it has been maint. properly - even syn. oil at all oil changes.
I am hearing that it "most likely has worn plastic on the tensioner arms", Anyone else hear of this???
These engines are notorious for making ticking noises and some are considered normal. There is also a condition called piston slap (more of a knock) that occurs at startup and Ford says not to worry about this either. I'd suggest trying to isolate the noise then going from there. If it is the belt tensioner and you haven't replaced it or the belt, it might be time to do so. Should be a fairly easy routine for you to do.
Well I must confess - I have an "in" at Ford - I am a designer in the Det. Area and work in the auto industry....
I also have family that works in the engineering department - I made a call, and my family member made a few calls. I received a call that Ford is going to take my vehicle and look at it and fix it!
Apparently, this problem has been on going in their "fleet" division and they have been looking for this problem in the Exp.
Got to love it - especially when I was dreading taking this thing apart and fixing it!!
My '98 4.6L has a ticking noise that I only hear at drive-through windows (the sound reflects off the building). It has been doing it for quite some time, but I keep forgetting to look into it. The sound changes with engine RPMs, but it sounds external to the engine to me. Proabably something in the S-belt like a tensioner or accessory bearing. "Mama" - keep us posted if you find the cause. Thanks.
very low about a year ago, then stopped. We thought it was due to the oil weight and the extreme cold weather.
Just recently, it has gotten louder and when I am moving it almost sounds like a "chain" is being drug next to my truck.
I just paid this thing off - it is in excellent condition (body and interior) and I refuse to buy another vehicle!
We also have an 1999 F-250 Superduty Des. (husbands work truck) - this thing has been wonderful and let me tell ya - I will drive it and I can park it! All the guys at work laugh at me because this is one big dog with the 8 foot bed - but everyone get's out of my way when they see me rolling up on them on the expressway...LOL LOL
I will keep you posted on the progress....
Thanks for all the input....glad I found this site today!!
I have a similiar noise coming from my 00Expe. I hear it with the windows rolled down and going fairly slow. Mine is not the engine but somewhere in the front wheels or suspensionon both sides. It actually sounds like a bell jingling! It drives me crazy in the summer! I have had two 00 Expe's and both made the same exact sound. Obviously it isn't serious and I think they all make that noise but I am just curious as to what it is!!! Does anyone out there know? My buddies 98 made the same exact sound.

I assume that these vehicles are all 4x4 models. Remove the plastic hub cap off each front wheel. Behind it you will see a sheet metal "castle nut" held in place with a cotter pin. When the vehicle was manufactured, Ford placed a small quantity of a black tar-like material inside the castle nut to hold it in place and keep it rattling against the cotter pin or other objects. If the material wears away, it will sound as if you installed a pair of wind chimes onto the front of the vehicle. Sometimes you can work the tail of the cotter pin to press firmly against the sheet metal and quiet things down for awhile. For a more permanent fix, pick up some high-temp RTV sealant and a pair of new cotter pins of the appropriate size, pull the cotter pins, place a quantity of RTV inside the sheet metal nut, and reassemble, using the new cotter pins. Give the RTV a little time to set before you drive the truck.
I didn't provide my vehicle info only because I was following up on someone else's post, but I have a 2000 Expy 4.6L 4x4 XLT. The ticking noise I'm referring to can best be described as a soft ticking that can be noticed when stopped next to a drive-up window. I noticed on another post that this might be the fuel injector(s)? I'm guessing it's normal and that's there's nothing to be done about it, but if anyone can confirm or deny I'd appreciate it!
Just an FYI, my tip probably doesn't address your situation, but should address the one that Skoiv described. If the truck is at a standstill, you should not hear the noise described in his post.
