Knocking sound noticeable during idle.
It seems to be coming from the exhaust manifold but can't quite pinpoint just by listening.
Seems more clearly heard from the front wheel well than from the top of the engine.
I've heard the exhaust manifolds warp and leak for these engines; is this true?
Not sure if this could also be a lifter issue.
Surprisingly, the vehicle only has 37k miles. I bought it new and have maintained it well.
A heavy duty truck with light duty usage... come on, this thing should be bullet-proof....
Any suggestions before I take it to the repair garage...
