Okay so i have a 03 2500 with a 5.7 hemi,
now i have always had some lifter noise but tonight it got worst then usual i could hear it over music and my heater with at idle, usually everytime i start it i hear some ticking which i know happens to all these hemis. It has about 136,xxx just change the oil about a 1000 miles ago usually do it every 3000 with 5-30 no synthetic and a factory mopar filter from the local dealer, if anyone has experienced these problems and sounds please let me know if you fixed the problem or know how to fix it!.. Thanks if you would like to text me or call me about it ask for the number thanks again guys.

 

Loose valves? Bad lifter? Exh leak?

 

Being an 03..... Broken valve spring??
But I would've thought you would throw codes and or have a really bad/no idle if that was the case??
Al.

 

sounds like you need to get a mechanic stethoscope (or make one) and figure out where the noise is coming from, and pop a valve cover

 

I'm not sure I have no leaks no miss at idle but it defiantly sounds like a lifter to me, anyone ever had a injector hang up ANC make this noise?

 

a injector hang up.. NO sound as NO moving parts...

 

Yeah it's for sure a lifter hanging up or collapsed I think I started it this morning and it did it for about 5 seconds and stopped doing it, anyone ever did lifters on a 5.7 hemi?

 

The lifters in your truck are rollers, I would suggest running several loads of seafoam through the crankcase first before you decide to pull it apart unless your REALLY looking for a good excuse to cam it. If you've been running Dino oil through for its lifetime, more likely than not, you've got a plug port on one of the lifters and you may get lucky and clean it out. Either way, if you do decide to pull it apart, if you flush it well, the cleanup won't be as bad.
I think I would at least pull the valve covers off just to make sure its not a valve spring letting go, or something stupid strange happening with the valve train.

 

Marvelous mystery oil, I used that in an old gm 350. With a collapsed lifter. Fixed it right up. Drove it another 100k.

 

Thanks everyone for the help appreciate it a lot, I think I'm gonna try seafoam and run it thru the case and see if there's dirt or something holding that lifter up, maybe run a thing of Lucas thru the oil as well, I have a appointment at the dealer here in town tomorrow morning, not sure what they are gonna do but said they will figure it out for me since I don't have much free Time of my own, I'll keep this post updated when I find out what's going on, if anyone has nah more suggestions please let me know, and if it has to come apart I'd like some ideas on a decent proformance cam and other goodies thanks
