Mounted on the engine block.
The knock sensor is located on the 95 oldsmobile 98 with a 3800 engine under the midpoint of the heads.
Sorry I am not sure how to describe this, but this is a diagram of a Bonneville and its in the exact same location,
usually 3800 pounds
3800? It needs a new harmonic balancer.
Around 3600-3800 lbs
Around 3800-4000 lbs
On the 2000 Firebird 3800 V6, the PCV valve is under the MAP sensor. It is on the top of the engine on the upper plenum.
don't think motor mounts will work - look for 92-99 3800
