Hey guys...I have a 2000 pontiac Bonneville ssei. While changing my valve cover gasket I discovered I have a hole in my valve cover. Are they interchangeable or can i only use one off an ssei??

Are you able to take a picture of the hole?

And no, you are limited to SSEi (L67) valve covers. Due to the fuel injector boss'* are in the cylinder heads vs the L36 fuel boss'* are in the lower intake manifold.

no it must be from a supercharged 3800

L36


L67

I can take a pic but not at this particular moment. I will post tht pic in here later today but someone drilled the screw tht goes to the alternator too far and went into the valve cover so theres a perfect sized screw hole in it. Im still driving short distances. The wife took it to work today.

Which cover do you need, I probably have it sitting here. Cheap
