gcozmo, good to hear that you had the problem looked after. Like I mentioned it sounded the same as the problem I had. At least you had a Dealer that looked into your complaint, I would buy from them again, as it seems they want repeat customers.

 

sounds like we all have the same noise. I've had mine for a year and it has 65000 on it. I was told it was the injecters. I learned to live with it I guess.

 

Wow! What did that cost you if you don't mind my asking?

 

It was done under warranty.

 

Most of the time it is the injectors. Don't misunderstand about the noise that I had. Mine has a injector noise as well that you can hear very plainly if you stick your head down near the fender well when it is running, heck you don't even have to put your head down, you can hear it just walking by. The noise that I had was a loud peck on both sides of the engine that you could here across a small parking lot when I would leave it running to go in to a store or something.

 

Yeh i have a 05 Explorer with the 4.6. It ticks from the left bank. It is not an injecter.It is driveing me nuts.There has to be a simple fix with out takeing it to a dealer. Dose any one have any imput on a proper fix pefor i take it apart and come up with one my self. Im sure the rest of you would like to know as well.

 

Anyone ever try any additives on these mod motors. Zmax, Rizlone, etc. or are these just for the older conventional motors?

 

I have been running super gas in my truck for the past 10 months and it really toned the noise down. The additives in reg gas just is not like it used to be... It is worth the extra few dollers that it is at fill up. Just try it guys for a few tank fulls and then post your results.

Yes ive tryed zmax. maybe a heavyer weight oil with a bit more viscosity (spelling sorry). but i realy think it is a miss installed valve guide on one of the valves so ther is im proper clearence between the cam and whatever ya want to call that thing a shim or tapit some ohe help. LOL

 

one item i did not see mentioned about the sound is the cam phasers, warmed up engine and the ticking disapears around 1200 rpm ... cam phasers.

 

Your tick ticking is most likely the cam phasers. My 04 did it as well and only did once it was at running temperature. It wont hurt your vehicle to leave it alone, but its mostly annoying. I actually brought my truck back to the dealer and for $1200 got the phasers replaced with the newer updated ones. Sounds a little extreme but i cannot stand any kinds of noises or rattles when im driving. (The guys that sell the sound denting material matting must love me by now) .......Advice: get a loud stereo!

my 06 superduty has this ticking noise which has progressed since ive had the truck im now losing performance,stumbling,back fire during a revup,cam phasers replaced and now left side lifters and rollers,hollow block motors are hard to diagnose for engine noise sounded like the left side it wasnt,still blasts through the wheel wells, open the hood it almost goes away,wtf,cant figure it out,any help?

 

The 5.4 is a overhead cam engine, which tells you it does not have pushrod's,hence it would not have lifter's. The 5.4 like most overhead cam engines use hyd. lash adjuster's on the rocker arm. They can and will bleed down and often pump back up when ever.,(different RPM"S, temps, etc.) My 06' 5.4---120,000 miles has this ticking noise plus several other ones> The phaser's advance or retard cam timing and this will also cause simular noise's. My problem noise is a low,hard,hollow,thunking on left side. The engine runs fine,but is losing power at times,no smoking,or smells. With all of the other noise's and power loss I am thinking of just replacing engine. I just thought you should get more than 3 year's and a 100,000 miles out of an engine.

 

I have a 2004 F150 FX4 that I purchased new in Aug of 04. After apprx 2 years it began to make a ticking noise similar to a lifter noise too. I checked this forum and found that there was a TSB regarding a "cam sensor" I believe. I took it to the dealer gave the the TSB number and they replaced the sensor no charge. It took care of the noise. I apologize b/c I don't remember the exact post or TSB number but it was here on this thread.

 

hydualic lifters are on the 06 modular 3v, had the ones the mechanic replaced in my hands.The loss of power is my issue is it a stuck valve if I kick it down to passing gear or even just try to get quick of the line it sounds like it loads up untill i let off a bit then it clears up,Im not driving it hard either.
