02 4.7 knock/ tapping sound
Hey guys I noticed a couple of days ago that there was a knocking / taping sound come from the passenger side of my motor, it has just under 219000 miles on it n its a 02 ram 1500 qc 4.7. I tried to use the search but couldn't find anything. Wat could this be n how do I fix it. Please help
Wow! 219k on a 4.7 thats up there.
More likely than not...your manifold bolts have become loose or broken and the tapping / knocking sound you hear is because of this. Put a wrench on them and hopefully they'll tighten up or better yet replace them.

Candidates for tapping on a high mileage 4.7:
Hydraulic lash adjusters collapsed
Timing chain stretched clanking around
Timing chain guides gave up ghost and clanking around
Valve guides worn

Well I no its not a exhaust leak because I have one on the driver side ( two bolt heads snaped off) so I no wat that sounds like LOL. But also when I take off the oil fill cap the sound gets louder.my dodge deal service center is telling me telling me that they want to pull the head n have it machined n all this other crap
Rear two heads on the driver's side exhaust manifold is by far the number 1 cause of clanking. After that, with that mileage I'd start to suspect a valve seat(s) is starting to go. Problem is it's a bit(h to pull the damn heads on the OHC 4.7 (ask me how I know!!!), but if you are going to the trouble of pulling them, have them rebuilt and spec new valve seats - should be about $400 for a total rebuild of both heads.
The three piece chains on these things are pretty damn stout and even at 200,000 miles you'll probably find the chains themselves are fine - but the guides are probably about shot. They can be checked when you pull the timing cover to remove the heads - but the guides are only about $10 a piece and are easy to replace...

Not to get you upset, and it might not be the source, but in '75, that type of noise preceeded me throwing a rod on my 442. The noise was from a failed connecting rod bearing and I embedded the piston in the state highway. The tapping can be an exhaust leak, but I would not drive it until you determine the souce of the "knock"
As I increase rpm the sound goes away which is making me think it the timing chain, I found a whole kit, chains tensioner n gears on eBay for 150 bucks how hard is this to do in my drive way n bout how long should it take to complete
