Hello all,I own a 20071500 with the 5.7LMDS Hemiand I recently changed my oil with Mobile 1 full synthetic 5W-20 and a K&N oil filter and some additive to help the coating. Since then, I have heard a ticking noise coming from my undercarriage (more specifically around the oil pan) when I am idling. I cannot tell if it is still there when at higher rpms due to wind and exhaust noises but I am sure it is. My question to you is, does anyone use anything other than 5W-20 with the MDS engine, I know it calls specifically for it in the owners manual but..... Also, has anyone had this same problem before? I really appreciate any help with this, if I have to change the oil again it isn't a huge deal because I have easy access to both Royal Purple and AMSOil so I will go to one of them if needed. Thanks again.

 

do a search you will find this problem all over the forum.. it is said to be nothing....

 

Sorry, didn't know exactly what to search for as ticking noise can be very vague, thanks

 

I have that same ticking noise on my 03, and I noticed it really bad whenI started to use 20w-50 oil. Cannot figure out what it is and I can only hear it when idling. My uncle has looked at it who is a pretty good all around mechanic and does not think it is hurting the engine, but he needs to dig aound a little to see what it is.

 

I have the HEMI tick as well. Started after I put on a CAI. Around here, it is said to be normal.
