RE: Ticking noise from 5.7 Hemi
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?
