I know i am beating a dead horse AGAIN but please forgive me. I have read over and listened to hitchhikingmike's post and video on his 2002 4.0 explorer noise. I believe i have a similar noise but the difference is mine becomes more noticeable when its warm and stopped in gear. When i put it in park it is almost unnoticeable and when in drive or reverse if i raise the idle to 1500-2000 + rpms it is gone. It is only noticeable stopped in gear between 1000 and 1500 rpms. If i pull next to a wall it sounds almost like a small exhaust leak but it is the (rattle in a can) if you listen close. It is not an exhaust leak or heat shield. I tried the 2nd gear 2000-3000 rpm listen test but nothing is heard in that range. Does this sound like primary chain or cam chain? I am sure it is from the front of the engine and can be heard from top and under the front of the engine. Belt was removed and noise remains. Other than the rattle she has 136000 no leaks and does not use oil. Mobil 1 5w30 synthetic high mileage oil with fram ultra filter is used with regular maint every 3000 and it has been great so far.
I really appreciate 2000streetrod's knowledge on the issue and would love to get anyone's insight or personal experience on this issue. Has anyone had this. Money is tight but don't want a piston valve marriage.
Thanks
