- Hemi 5.7
I have a 2014 5.7 hemi 135K miles. Engine light is on and code is p0302 and it's ticking. Ticking is louder on cold start and then fades some when it warms up and when I'm driving. Truck runs smoothly (no mds with engine light on) but it idles a little rough. Mechanic says spark plug and coil are ok but it probably needs new lifters and cam and says thing to do is new engine instead of replacing lifters and cam. Before this happened, truck was running really well. Is it worth it to just replace the lifters/cam or is it better to replace engine? Any thoughts would be appreciated - thanks.
