Hi guys

I have a 1999 f150 with the 5.4 litre engine with 120000 kms on the motor.Yesterday as the wife was leaving home i noticed a tick coming out of the motor as she was leaving.Took the truck for a ride today, the noise seems to disappear as you increase speed or you just can't hear it at increased speeds. Any ideals on what the promblem is and how to solve it would be greatly appreciated.

Thanks

 

If this is a problem, well, I think I have the same one. I notice a ticking when I'm in third gear. Once it switches into fourth though I don't hear the ticking anymore. Please help the both of us.

 

I seem to have the same problem on my 1998 but only notice it when idling. It is really noticeable when i am in a drive thru with a wall on the drivers side. I'm clueless to what the problem is, so anyone got any ideas?

 

I have the same thing at an idle it has a slight clicking, I have come to believe that it is the fan clutch bearings getting old, on a 2000 5.4 w/67400 miles on it

 

Check the pass. side exhaust manifold, the rear bolts. Mine broke and the dealer said this was common for my year (2000). Mel

 

Thats interesting, and you never got an exhaust smell in the cab from the poor seal.

 

No smell in cab.
Also the manifold was warped. The dealer said its like the chicken and the egg, did the manifold warp and break the bolt or did the bolt break and warp the manifold.

 

97 150 4.6 120000 miles on it when mine started ! sounded like a rod but it was'nt inside of the cat came apart and a small piece was tapping around in the pipe . it finally flew out ! no more sound

 

I got a ticking noise too, could be an exhaust leak.

 

I have the same noise at idle, I noticed it at a drive through. I have a 03 F150 5.4 it has 15,000 on it. I opened the hood and used a sounding stick. It seems to be a couple of noisey injectors. I took it to Ford and they said this is normal. I am going to keep a ear on it though.

 

try a higher octane, or a fuel cleaner...

sounds like my problem i have a 99 f-150 4.6 with 43k, its on the pass side motor, exhaust man took a stethascope to the manifolds, and could hear a tick, but a metal tick, not like an exhaust leak, so i was under the hood and i toucked the injectors and could feel the ticking, and yes when between a wall or buildings, you can definately hear it.

 

ford is having valve guide problems with there heads.if you stick your head in the fender well or underneith the truck near the cats and hear it its more than likely worn guides.ford has updated heads that fix the problem.

 

they gonna fix it for free??
