[V8] [Bulk] Piston Rings, ring groves?

[urq]

There was a company that made rings for the PT engine ... it was a company
called Devek.  I believe Devek was more well known in the Porsche 928
circles.  It appears that Devek is no longer in business.  When I searched
my archives I found that Marc Thomas may have been the owner of Devek ...
Marc is also an urq fan.  

It looks like Devek may have been swallowed up by Wolfsport, which I believe
is now Karmakanix ... which brings my thought pattern full circle.  There's
a guy in Berkeley (or thereabouts) named Steve Nechodom, who was quite
knowledgeable about the PT engine.  I almost had my engine reworked by
Karmakanix, but it sounds like Karmakanix may have gone more mainstream,
last time I talked to them they didn't seem too interested in my old PT
engine.  

There is someone I believe is still on this list, Pasha, who rebuilt his PT
engine with Devek rings.  ISTR having a Devek datasheet which had the
details on the rings for the PT.  

I guess my first shot would be to see if you could get information from
Karmakanix ... http://www.karmakanix.com/ ... I'm also hoping that Pasha may
pass along some of his BTDT ... 

Let me know what you find ... I've managed to get a gasket set ... even
enough valves to do an engine ... the engine in #344 is in need of rings ...

Nick,
I'm sure we can help on the Audi  also just need to know the ring groove
widths and depths.

So, I am looking at rings for the Audi in particular because I'll need
something to do come summer, and I think doing the piston rings to clean up
the oiling problem would be nice.  I'm looking around for a good set of
rings for my Miata as well, and these guys have good reviews and seem pretty
knowledgeable, So I think gapless rings for the M-s Miata will be just the
ticket to fix the oiling problem I have.  (boost pressure pushes it past the
rings)

Anyone know the Ring groove widths and depths off hand, or otherwise?


On a completely unrelated note, anyone have experience with boosted motors
pushing oil into the intake tract and what/why exactly this happens?  I/we
have many theories, but I know this is nothing new in the FI community, as I
remember my 5ktq and 200 did it as well.
