I have always heard a ticking noise coming from the engine bay area. I purchased a set of headers and installed and because I was told that the exhaust manifolds were warped. I took truck into dealership and they said it was from my headers. I believe the sound is coming from the bellhousing because I have heard teeth grinding when starting.

Sounds like "Hemi tick". Do a search on here on it and you'll find a ton of info. If that's what it is, I've never heard anybody attribute it to headers/manifolds. Any grinding sound would be something completely different and not at all normal.

 

Mine only ticks when extremely cold. It is gone after about 5-10 minutes of driving though. Sounds almost like piston slap or something.

 

I think its most likey a "hemi tick" but mines all the time. Have you changed to a different oil? Or changed what gas your using? Maybe you can try an oil additive like Lucas Motor oil might help!

 

I took my hemi to the dealer and they compared it to to another hemi and it was the same sound coming from the same area and ive heard others and they all sound the same... so i wouldnt worry about it..

 

beleive it or not my boss tried everything to get rid of the "tick" Just the other day we changed the oil to Royal Purple, and he hasnt heard it since. I really didnt believe it at first unitl i listened to it, and sure enough it is gone.

 

ive been using valvoline 10w40 synthetic. I am going to try royal purple but what type should i get and where? The ticking noise is driving me crazy i have a great sounding exhaust but when you sitting in traffic you can just hear the tic-tic-tic and it drives me crazy.

 

You need to use a lighter weight oil, your truck does not call for 10w-40 even though it's synthetic. I have a 2003 hemi and was useing 10w-30 when I also heard the ticking, so I switched to 5w-30 and amazingly the ticking vanished!!! I believe your's must be ticking loud with 10w-40. What made you use 10w-40?

 

My 2003 hemi has that ticking sound to. When I start cruising on the highway I hear that ticking sound. I use 5w30 oil and still hear the ticking. I can live with it. dave

 

Yes change to Royle Purple, Redline or Amsoil. If it still is there then consider putting in 5w-20 instead of 5w-30.


Hope it helps!
