Two or three oil rings?

[Jon]

I thought one of the problems with having a turbo installed an older
3208 engine that it only had two ring on the pistons. And the latter
engines ran with three, I'm I right? And this can cause problems with
only the two rings.

The 3208Na, 3208Ta, and 3208ATAAC (Natural, Turbo, Air-To-Air-
Aftercooled) all were 2-ring engines. The 3208 was designed as a two-
ring engine, works fine that way. The amount of friction, cylinder
wear, all work fine with two rings. The third ring was offered as a
retrofit starting in the early-mid '80s as an answer to competitors in
the replacement-parts industry offering a 3-ring piston for the
3208, ... nothing more.

Them 3 rings might have been an effort to stop the serious fog job from a cold
start that "throwaways" were so famous for. Kinda hurt diesel image, like 5.7
GMs.
