Finally found the source of my rattle.
It happened at low RPM's after the shift in any gear.
I thought it was engine knock/ping but it happens with little load put on the engine.
Exhaust crossmember welds checked ok.
Surprised what it turned out to be and how much racket it made... All the time
Right below the intermediate shaft there is a heat shield. Right behind that shield runs a vacuum line of some sort, not sure what it is ??
So i pulled the shield away from the line. What do you know ? Rattle is gone.
Just something to look into
