Injector Hammer?

I had a Thread going on an engine noise a few months ago. It sounds like a loose Tappet in the old school engines (valve rocker when the valve adjusters were on top of the push rod on the valve rocker arm). Anyway, taken back to Stock tuning, it went away, done a few thousand kms in the past few months. Nothing, Nada, Zip... OK, Bored, tuned it back up to rubber burn level 1, and the noise is sporatically back!! Maybe half the time at an idle, no clue...!!!

Sometimes there, loud tappet noise, like a leaking hydraulic lifter, sometimes not there and fades away to general normal diesel rattles and injectors noise.... Could this be Injector hammer? On just one? If so, is this something I need to fix? I have no experience with this common rail type electronic fired injectors, only pressure fired old school stuff... HELP!

It just bothers me, I am fussy about my gear.... Maybe increased line pressure Injector hammer on SuperChips level 1, ???? Ignore it????

God Bless America, Quarter Horses, and FORD....

Best Regards from Down Under...

if the chip is messing with injector pressures, you could just be hearing more injector knock which would be completely normal.....your just hearing the noise when the amplifier piston is doing its thing.....

My truck would sound a lot different when I kicked the switch on the TS to 140, especially when I was really "hammering" the pedal....

Just curious if you ever got this one figured out. I think I have the same thing going on. Truck runs great, just have a ticking or hammering sound during idle. I can't tell when I am driving, too loud. It almost sounds like tapping on a thin piece of metal like engine or tranny pan kind of noise. To me it is worse right at first start up and seems to go away as engine warms up. Just curious if you figured this one out.

Thanks

Hello Dodean, I am going to accept Marc's analysis on it.... I hear the same noise in about half of our 7.3's that come in here, mine is just the loudest, with only one other one rivaling my noise level... I will accept the answer from Marc above that it is OK... Amplifier Piston doing it thing... I assume that is the high pressure injection pump, right Marc?

All hail Marc, great Ford Guru, and tireless helper to us all on this Forum... Marc you are to be thanked "For Service Above and Beyond the Call of Duty"... Cheers..

Anyways, I accept that it is normal, the only other one that was AS loud as mine only had 7000 miles on it.. Hardly worn out... Ha!

It might be a result of altered exhaust or something that makes the inherent noise seem louder. Anyway, I ran mine hard for 5000 kms, no change, any serious engine noise or hydraulic lifter leak would have burned a valve or blown something by now, and zero, zip, nada.... I still notice it come and go, but no longer worry about it.. So there is my best judgement Dodean..

Regards from Australia... Lone Ranger

Hey guys, I'm another one who experiences a similar noise. It is relatively loudest when my truck is started on a cold morning (overnight temp in the teens). When the vehicle warms up, it gets quieter. When ambient temps are around 50 degrees and warmer, it's really only noticeable at idle, or sometimes partial throttle when I'm cruising.

How'd you guys make out on this? Any of your engines grenade? Or are you still living with it?

I'm located in Colorado. I'm wondering if our fuel here, our altitude, and our temperatures in the winter contribute to the effect.

Diesel engines are inherently louder when cold. The fuel is more viscous and harder to inject.
