I have a 4.6 2v that is ticking but not all the time.It started after I put stage 4 cams on my mustang I put new cam gears new timing chain kit,new lifters,valvle springs and retainers
It started after the install so I went back and thought it was the alternator bearing so I replaced the alternator.that wasn't the problem so I went ahead and changed the spark plugs to 3 degrees colder ngk and that didn't fix the problem either.I also I have new msd coils.i really don't know what it is honestly and I know it's not a rod bearing or anything else because it only happens at idle for a couple minutes then stops for about 5-10 minutes then comes back again.and it's not anything bottom end as well because I put lucas additive as well and put a much thicker oil and it didn't work.
