I believe I am hearing a different knock from my 05 d max with 82000 miles. i notice it at mid range when engine is under no load. I am not sure if its normal or im falling to pieces any thoughts?

any white smoke or anything?

i dont notice any smoke at all but there could be a faint smell of fuel or oil in cab

lly's do have problems with #2 and #7 injectors...
maybe try and get them tested

would they make a nocking noise if bad?
