I've noticed a tick...tick...tick noise the last few times I started my truck. Seems sometime it's louder than other times. I've heard of injecters making this ticking noise, but is this normal? Should I bring it in to have this checked?

Does your truck still move under it's own power? If so and your dealer contacts STAR, the tick will be labled normal and repair is not required.

 

LOL!! Sad but so very true.

 

I guess what I should have asked is, does anybody else have this ticking noise? Could this be a sign of a bad injecter? It runs fine and idles smooth. Just was concerned with this ticking noise.
Thanks Wayne

 

Hey...I have that same ticking noise in my pickup as well. I have a 04 with just a tad over 27,000 miles on the odometer. I took the pickup in a few weeks back and the tech people, at DC seemed to think it was an injector. The delership did find something wrong with number six injector and promptly replaced it. This seemed to intensify the ticking so I took it back to the delership. As it stands today, the engine has the head removed and there seems to be nothing wrong with any of the cylinders. Strangely enough, number six cylinder's valves show some sings of pitting and I think that is a little strange. The mechanics seem to think it is a wrist pin, as do I. However, DC does not share the same view and wants the delership to run more "tests" after re-assmbling the engine. This is complete BS!!! My delership would like to install a new engine and go on about it, but DC says no. I am at my wits end on this one!! There should be no "ticking" at all. I do not think this is normal and will argue this point with anyone on this forum. I paid forty thousand bucks to listen to a tick going down the highway??? I don't think so.......

 

southtxfarmer74,
Do you hear this ticking after the engine warms up? Seems mine is not as loud after warm up.

 

Im with southtxfarmer. Mine is at the dealership for the exact problem and it may get left there if we dont come to some resonable concluisoin. I have had enough of the tick tick knock knock stuff. Star is a complet load of crap. This is the 3rd time its gone in for this and it is now a knock instead of a tick. Hopefully I dont get the its normal line of crap again. If so I may head 2 blocks down and trade for a GMC D/A truck. Star has pushed my buttons far enough with that line. I am not going to be making payments on a truck that sounds like it is on its last leg with only 14000 miles on it. For those wondering it has the nois all the time. Cold/Hot/Idle/all the way up to however high you push it. It is most predomanet around 1500-2000 rpm. It does it under load or no load.

 

The engine ticks all the time. It is most noticeable at around the 1500 to 2000 rpm range as well and seems to get louder when the engine warms up. I still think it is something mechanical and not a faulty injector.

 

I have an 04 with 38k. When it's really cold out and I first start it in the morning and drive off when it's relatively cold, I definitely have a slight ticking noise. I'm not sure if it's new or if it's just due to the cold weather. The noise seems to go away almost if not completely once the truck is warm. Sounds like some of you guys have a different issue, or just far worse?

 

I have the same issue. I have a 600 with just over 17,000 miles on it and the tick and knocking have been there since the 9,000 mile mark, it was silent before this magic number. It's been for repair three different times. First time they said it was a loose fuel line and they tightened her up. No fix. Second time they say I have two bad injectors and my truck has been idling too long. I say bullspit to that. Anyhow, they replaced the two so called bad injectors. Again, no fix. This last time it was in for about four weeks. I convinced the dealer to sublet the work to Cummins and they did. Cummins had the truck four weeks and replaced all six injectors, a fuel line that they said was over torqued (go figure) and two rocker arms that were loose. Picked the truck up on Dec. 23rd and the tick and knock were better if not almost gone. Guess what...it's back and just as bad as ever! When I've let the truck sit outside for at least 12 hours and started it up it's as silent as a mouse, but once it starts to warm up it starts knockin and tickin. Once she's up to operating temp its full blown and I would bet money it's louder than the 2nd gens. Dealer is now getting back with Cummins, who said it could be that there are other rocker arms that need to be replaced because they are loose too. At least the service manager at the dealership is dedicated to getting this thing fixed. He even agrees that it's not right and that STAR should just let the mechanics do their jobs and fix them. I keep telling them to check the push rods to see if they are bent and that it's at its best when it's all warmed up, we'll see what happens when I take it back in.

 

Mine started the ticking/knock about 7500miles. Then the white smoke on cold starts, rough idle and louder knock. Diagnosed as bad #6 injector. Dealer replaced #6 injector per Star. It was much better for about 1000 miles, now starting to hear the tick and see a little very smelly white smoke on cold start. Probable another or same injector.

My experience is that it has to get real bad before Star will let the dealer do much of anything. I am just waiting for it to get worse.

 

As loud as a 2nd gen?? Jeez, I wouldn't call that a 'tick'. I think the bad injectors/white smoke is a 600 thing. I think I'm just listening to my engine too closely and need to turn up the stereo.

 

Oh Lightman....tickin and knockin, tickin and knockin. They (Cummins and STAR) all thought it was bad injectors too, until they replaced all six and the tickin and knockin was still there. The white smoke at cold start up is normal. All diesels do this when it's cold out. It's the water vapor meeting the cold air. Now once it's warmed up and if it still has the white smoke, that might be another issue. I don't have any white smoke once warmed up. Only on cold starts when it's cold out and it's only for a short while, then it's gone.

 

Mine started making that noise.
I started adding about 4oz of STANADYNE with every fill up. No more ticking.

 

I talked to service rep todayand he said Star told them to pull and clean all 6 injectors. They told me it ideled to much . I told them that that was the biggest load of crud I had ever heard. They said it ideled 28% of the time. Now I admit I let it idle for a few minutes when it is below abought 40 deg out but 28% of total engine run time?? I dont think so. With 14000 miles on it thats a heck of a lot of idle time. When its realy cold out it may idle for 5 minutes max before I take off. When its above 45 or so I dont let it warm up at all I just start and go. And to top it all off sence its been real cold out I have gotten a work bomber to drive so the truck sits most all week long now. Anyhow we will see tomarow waht they found out.
