read this TSB. I have to have mine looked at as well.

TSB

I am aware of the TSB, but the noise is present at a cold start-up which is not characteristic of the symptoms of TSB 06-8-11. Thanks for posting, though.

Not a big issue

The ticking is not a big issue as it is not loud enough to bother me. The TSB for "ticking" has been around since 2003 or thereabouts with this Duratec 3.0L. I do not believe that the tick is doing any damage or the engine would register some type of malfunction code. You can hear similar ticks in other cars/trucks as well, but unknown whether the tick is injectors firing, camshaft tick, or timing chain noise. The cars/trucks with a metal chain typically produce more noise than those with a belt. The engines in my '69 Camaro SS and '72 Ralley Sport made plenty of racket...all as normal.

If you think the noise is due to the camshaft tick TSB, then when you listen to the engine the sound should come from the back of the engine near the firewall on the passenger side. If the noise is related to the timing chain, then the noise should be more toward the middle-front of the passenger side. My dealer, who was not familiar with the TSB, had a couple of techs listen to it and both said that it did not sound abnormal and keep an "ear" on it to see if it gets worse. If it is a "problem," then it should manifest itself pretty quickly.

Correction

The TSB noise is at the middle front of the engine, near the camshaft driven water pump. I thought cylinders 2, 4, and 6 were on the firewall side of the engine, but I was wrong. On a "fresh" cold startup where the car has been sitting overnight, my engine does not make the noise for 3-5 minutes, so I will be taking it in next week to see whether the TSB might be applicable here.

TSB was done...no joy

The TSB was done, but the noise remains. I got out my mechanic's stethoscope and started poking around the engine trying to identify where the noise was coming from in the engine bay. Timing chain area...nope. Various areas of both valve covers...nope. Alternator...nope. Waterpump...nope. Power steering pump...nope. Intake and exhaust manifolds...a little, but not very loud. Fuel injectors...BINGO. The same "ticking" or "tapping" I hear in the engine bay, even with the hood closed, is the same sound I get when listening to the fuel injectors doing their thing (opening and closing). The noise is present at the same intensity, as far as I could tell, on the three fuel injectors I could reach with the stethoscope. I know loud fuel injectors are not something new, or a problem. It's only annoying cause I know it's there. I guess that is what the noise is. I will follow up with the service manager later as he is going to contact me the next time one of the Ford engineers visits so the engineer can have a listen.
