I HAVE AN '03 2500 CTD. I HAVE NOTICED A TICKING SOUND ALMOST "LIFTERISH" SOUNDING. ESPECIALLY WHILE ACCELERATING. I HAVE HEARD THAT THE AEM COLD AIR INTAKE CAN MAKE EVERY NOISE IN YOUR INDUCTION SOUND 100 TIMES LOUDER. INCLUDING THE EGR. OR COULD IT BE AN INJECTOR DUMPING OUT? I GRABBED THE LINE RIGHT BEFORE THE BLOCK ON THE FIRST INJECTOR AND IT WAS PULSATING...ONLY ONE DOING IT.
ANY THOUGHTS?

you check you engine codes??

 

[cmns2500]

the 03's ain't got egr, i don't think...........:WHT::dunno:

my truck makes a tickin noise occassionally too, but i don't really worry bout it

 

[bill9009]

Yeah you dont have an egr system, And my truck rattles away, but its a diesel so its kinda normal. Did this just start happening?

 

[NickBeek]

The number one fuel line on all CR engines pulses like that. Ticking is also a common trait on CR engines. Mine does it on and off. Id it running any different?

 

[dieseljay74]

Well....I noticed it starting this winter...but i think I probably just didn'y hear it during the summer with the windows down and radio etc...
It doesn't really run any different, just a little louder and that damn tickinh sound. I guess it's just a diesel joy eh!

My 05 had a noticable "lifter tick". I change the oil (was last changed before i bought it) , put in 15w40 rotella and a qt of lucas oil stabilizer. POOF , no more tick.

 

[cowboy352u]

the valves probably need adjusting. had mine done at 29000 miles and it sounds better

 

[dieseljay74]

Well fellas....put in some lucas oil stabilizer and a fresh tank of fuel....whalla....no more ticking. I don't know if it was the oil treatment oe a bad tank of fuel previous? Either way...gone now!

 

[bookworm]

that is exactly why I use Lucas oil stabilizer in my Freightliner. 2 gallons Lucas, 8 gallons oil. 830,000 miles, it sure helps quiet the old pig down.

 

[rcmaddman]

I was thinking about this today. My truck hold 12 and a half qts of oil. I put 1 qt of lucas in. I think my ratio is off a bit. I think its supposed to be 1 qt per 5 qts of oil. I think next oil change I will put 2 qts of lucas to get the correct ratio.

 

[bookworm]

Welp, Lucas wants you to put in 20%, but I know several folks who use 10% and have good results. Lotsa folks on here will castigate you severely for putting any additive at all in it, and I don't put additives in my 30k mile CTD PU, but....
The Freightliner has a ton of miles on it, probly could use new rods and mains. The additive certainly helps, I maintain 10k mile oil changes, and it uses no oil ( ok, maybe a small amount, a qt or 2, but it leaks most of that...) betwixt changes.

 

[dieseljay74]

I think I am swithching to Rotella myself next earl change. Hear lotsa good things about it. Lucas also....though I agree with the chastizing due to additiive use...everyone has their opinions.

get the sythetic stuff

it's amazing:gr_patrio

I run the synthetic Rotella in my CTD. Like so much else, oil brand is a matter of personal taste, but I figure if it meets manufacturers specs, then it's fine.

 

[JETFUEL2008]

Cummins wants you to use Valvoline, but they will tell you off the record that that Shell Rotella is just as good maybe better. I personally run Rotella with the fleet guard filters from Cummins, dont buy any thing from Dodge they will rob you. Mopar fuel filter 47 dollars 10 micron. Fleetguard (cummins) 7 micron 15 dollars, no brainer same goes for the oil filters, I experienced that yesterday.

 

[cmns2500]

i'd run the cummins/valvoline blue synthetic, if i could find it anywhere around here:dunno:

 

[JETFUEL2008]

You can order it directly from Cummins, the price is not bad either. Just courious how often does every one change there oil. I have been changing mine about every 3500-4000 miles, and that stuff is black as coal, heck its black after I change it.

 

[cmns2500]

cool:tup:

can ya give me a price per gallon on it, please;D

 

[JETFUEL2008]

I was just in the Cummins store here in Indy yesterday I think it was 16 dollars a quart.
