Ticking 2007 5.7 Hemi
Another vote for exhaust manifold leak.
Have not seen many 2008 and earlier 5.7L Hemis with the bad lifter problems. The lifter and camshaft failures seamed to come with the engine and body style changes in 2009 and later model years, but not 100% sure on that. Mine is a 2008. Had a broken stud on right side exhaust manifold since about 13,000 miles. Last winter it started noticeably ticking pretty loud at cold start up with around 200,000 miles on it. Now this summer it's ticking a lot more noticeable than ever, but has clearly become a regular sounding exhaust manifold leak so it's annoying and is time to fix it. It has about 250,000 on the odometer this week.
