Metal to metal sound
 

I just started hearing a weird noise kind of a tick maby a knock this is a 99 Cummins dreded 53 block with 63,000 original miles also looking for a new long block soon but would like to keep this one going as long as I can before the swap don't know how to send a you tube link but I will try

i should have included more info the truck still runs good fuel pump vp44 was re[laced along with the lift pump truck has 63,000 original miles there is no modes this truck dose due pulling but nothing more than 6,000 pounds and that was once i drive it daily now befor this year it oly went out on wekends never been beat or abused

has this truck been sitting for a long time? that's some really low miles. try running some Lucas oil treatment in the oil and some lucas fuel additive or similar stuff in the fuel even add some Dextron 3 ATF to the fuel it is probably something simple.
Check your fuel quality for bad fuel maybe detonation.
I wouldn't worry to much about having a 53 block mine has 278000 on it. Best thing is to not shock it temperature wise, in other words let it warm up when its cold out and keep it plugged in when its extremely cold.

It did sit on and off I always drove company truck until this last year I run Lucas in everyoil change from 40,000 up I haven't run any in the fuel I ran atf after I replaced the vp44 I'm going to figure out how to get a video link today

Sounds great to me has a little rocker noise but nothing to worry about.

What kind of oil are you running?

Go advanced on the lower post reply tab then select the weird looking icon next to the hour glass and the picture Icon and paste your URL there. (When you hold the pointer over the weird looking icon it will say insert link).

Valvoline diesel Cummins recommended with two courts Lucas oil stabilizers

i changed the fuel filter today but still the same ticking noise cracked all injectorsno air in the lines i did here that the lifters may need to be adjusted i am trying to figure that out now .
also running lucas fuel injector for the last 50 miles no change in sound
