Chris, I should have prefaced my rings remarks with first you need to
see if the turbo seals are leaking, they seal best when running, and
not so well at idle, so check that first, if it's not that, it could be
the rings, then try the heavier weight oil. Mark durham

I think it’s ridiculous to blame the total seal rings. It’s well known
that at idle, the most manifold vacuum is produced, and that’s when
the biggest load is placed on the carbon intake seal. (other than
slamming the throttle body closed after a high speed run). This is
when the seal leaks. Also remember the piston ring–like seal on the
hot end. Too many red Herrings have been introduced into this
discussion.
If  the rings were installed correctly, and obviously they were, they
should be holding up as well as any other quality ring.
