knocking

Is it actual mechanical knocking, or could it possibly be the "dieseling" knocking that happens when that nut at the bottom of the egr tube comes loose?

im not sure. its almost non existant at idle and i can only hear it now if i pop the hood and rev the engine.

i would be interested to see the diagnosis on this.. i've had a tapping under the hood for awhile.. assumed it was my valves, mechanic said he wouldnt mess with it unless it got worse

[bigkoala1]

my mechanic also said sont worry about it unless it gets worse

check that nut under the egr valve,mine didnt git put back in when i had my intake gaskets replace and made noise that sounded like my engine was tapping,i was so relieved when my noise was gone after i put it back in.

[bigkoala1]

will do. ill keep you posted

Depending on current mileage, maybe your mechanic(s) are just thinking it may be close to valve adjustment time. It's difficult to differentiate between the two (valve noise and loose egr nut) without actually hearing it though.
