SignUp Now!I'm not positive but I think the 3.0L Buicks that our heads came from have the same cap. If it's not the same it's really close. You might try GM and see if they have any left.
If it is the same as the GN's I have one.

No, the GN cap is different as it screws into a metal riser tube off of the valve cover. The TTA screws directly into the valve cover.If it is the same as the GN's I have one.

I have one that came off of my TTA that I recently sold. Still Kicking myself for selling it but I needed a truck.. I did the breather mod and forgot to put this in the car when it was picked up. It is the original grey oil fill cap that screws on. It is in great shape with all of the writing on top still on it. You can have it for 25 bucks if you want it.
Let me know
Nick
Do I get $25 too? lol
I'll drive to the yard and go pull one lol
