Okay, I've got some angry clicking sounds coming from underneath my pass side valve cover and my MPG has taken a dump (both happened a day or two ago). I'm 99% sure it's not an exhaust leak, so my question is this:

If I bent a pushrod, cracked a spring, or killed a rocker arm, can I replace the individual component, or is it a better idea to replace the set? For example, if it's a pushrod, would I be better off with a new set, or would one replacement suffice?

This is a DD with a catback and a lid. I do some spirited driving, but nothing crazy

 

prolly a cracked spring or bent rod. if one of your rockers, make sure u immediately check your oil for needle bearings. time to take off valve covers and check oil for debris.

 

What have you been waiting for....when you get a unusual noise from under a valve cover it is time to take a look see...what ever it is shure will not cure itself.....a set of molly PRs will cost ya about $100 so spring for a whole set...if it is a rocker puking it roller bearings I'd say get a whole new set of rockers...I would be surprised if it were a spring usually when you break one of those it has major damage....pop that valve cover and give everything a good inspection and find out what is causing the noise.

 

It just happened and weekdays are workdays.

 

I hope that you are smart enough to not still be driving it...
