......Can anyone give any advice as to how to make sure the right oil rings are used?

The inside of the tailpipe can get black on our 2002 3.2 & we rarely have to add any oil between 4000mi oil changes.
As far as the piston rings go, how I understand it is, the issue is not with the ring pack, but the oil return holes machined thru the pistons. You will need the *new and improved* pistons with more oil return holes. Have you tried an over-night cylinder soak with seafoam (or the likes)? I wish I could get ahold of an oil burning 1998+ 3.2/3.5L to try this on!!! I bet it would work!
