Just bought a 2008 Ram 1500 crew w 4.7 auto trans 164K miles. 1st Dodge I've ever owned. Upon first starting there is a tapping/ticking in the engine. While idling it will stop, then start, etc, continuing for as long as it's running. Can someone enlighten me what this is and whether I need to be concerned about it?

 

Check passenger side rear exhaust manifold bolts. They will break and cause exhaust leaks.

 

How's the oil level/condition?

 

it isn't an exhaust leak, familiar with those. Full of oil, not yet time to change.

 

My bro in law had an 04 1500 crew w hemi that did the same thing, except the ticking in his engine never stopped.

 

Lifter sticking? Try some MMO right before you change the oil

 

Thanks
