For at least 6 months now my 99 4x4 Durango SLT with the 5.2 (248,200 miles) has been making a knocking noise i can only hear it at idle loud enough to be heard inside the truck. At one point I thought it was coming from the left side but the other day it was making a loud pinging from the right wheel well, it would get loud then quiet but still noticable, kind of scary. I know for a fact that it does it when its warmed up, and probably when its cold too. Its getting worse! and I do NOT want to end up damaging it by not getting it taken care of.
Could it be that the timing is off?
Its about due for an oil change and I replaced the cap and roter, OEM champion plugs and wires...3k miles ago, and fuel pump...1k miles ago
From my experience with fine tuning carburetors in small engines, when I replaced the plugs I would say that a few looked to be running lean.

I already replaced the distributor cap and rotor, last time I changed the oil I used 5w30 because it was winter.
I will change it again, with 10w30 but it still knocked last time I changed the oil. It does use some oil, it leaks a little bit and burns a little but not bad, and I do not let it get lower than a quart low. To to just throw some numbers out there possibly uses about 2 quarts for every 5k miles..more or less....

Ok I will check the distributor shaft for play, and every last bolt on my valve covers came loose and started leaking so I tightened them back up, ill get 2 gaskets, and take a look inside I already know what its going to look like.....dirty. I stuck my finger in the oil fill hole onetime and it was like scooping icing off of a cake, thats how bad the sludge build up is in there. I can clean the valve covers but how would I go about cleaning the valves and all out?
