HELP-- Could it be a lifter ?

i have a 2005 f350 that just turned 140,xxx mi,

i always use Mobil 1 fully synthetic & always run 2 stroke in my fuel,

truck has never had a prob except for a number 4 inj.

now i hear a ticking noise like a lifter in a gas motor & sounds like it is up high.

it does not seem to get louder when i give it more fuel (rev it up) & sounds like its on the drivers side.

still runs perfect no missing or stumbeling.

do u think it could be a lifter ?

thanks for all your time & help

only mods are a
AFE intake,
zoodad,
straight exhaust,
superchips

Does it tick with the RPMs? Higher to higher. Lower to lower?
It could be an injector stuck open. Except I haven't heard of that happening much on HEUI injectors. Heck, I'm not even sure if HEUIs can stick open. Had a 5.9L Cummins that did but that's common rail.

Yes HEUI injectors can stick open. If there was an injector stuck open I think you would be getting some raw fuel from the tail pipe though and have a bit of a miss. He says it's running perfect.

Does the tick increase infrequency to follow the revs of the engine or is it constant?

Its just a constant tick, it (might get higher with the reves), but it runs perfect & does not miss @ all.
As far as my egt`s i have all straight pipe, i baby the truck & no matter how far i drive it, i always let it cool down before i shut it off. (also let it warm up before i leave.)

very well taken care of, i been driven it like this the last two days to work & back( 200 mi)
& has not got worse but has not got any quieter)

Every since i owned the truck sometimes when i would let of the gas @ a coast it would get total silance, (i heard other guys say that too) but now when it goes to the total silance u can here the ticking.

It's important to determine if the tick is in sync with rpms or remains constant.

Don't baby it either. They need to be driven hard and work the turbo out or you will end up sooting up the turbo vanes till they stick.

I have the same tick. Can really only hear it at idle, and it's been getting louder for months now. I have asked 2 dealerships and 4 independent mechanics if they think something could be bent (valve, push rod, lifter, etc.) and they all say probably not. But the ticking keeps getting louder.
