Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 18 years and I will do my best to help.
I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on...
Is it a tapping or knocking sound? Also if it's taping is is coming from the valvecover for #4 cylinder? I ask because we have seen quite a few rocker arm assemblys fail and cause this issue.. I would pull the valvecover and tell me if you see the rocker arm assy has eat into the frame of the rocker arm rails.. If we can catch it soon enough you only need to replace the rocker arm assy, but in your case it's misfiring and it's burnt the valve so you will need to pull the head to replace the valves and rocker arm assy..
If you need anymore assistance feel free to reply and don't forget the RATING before leaving the site!!Have a great day,Brad
