Is the Oldsmobile engine an interference engine?

The Oldsmobile engine can be both interference and non-interference, depending on the engine model and year of production.

For example:

* The Oldsmobile 3.8L V6 engine used in certain Buick, Oldsmobile, and Pontiac models from 1988-2008 is a non-interference engine. This means that if the timing belt breaks, the valves will not contact the pistons, preventing severe engine damage.

* On the other hand, the Oldsmobile 3.4L DOHC V6 engine used in certain Cadillac and Oldsmobile models from 1993-2005 is an interference engine. If the timing belt breaks in these engines, the valves will likely collide with the pistons, causing significant engine damage.

It's crucial to refer to the specific engine specifications or consult with a reliable automotive source to determine whether a particular Oldsmobile engine is interference or non-interference.
