<VV> Oil Control Rings

[Mark Durham]

Gary, your cylinders and rings are worn beyond limits. I had the same
problem with my engine. My oil control rings also fell through on my
Cylinders. The cylinders will be to worn to just hone and re-ring.
Gaps should be .010 to .020 at install As stated in my GM overhaul
manual, page 6a-39. The book says operation is not affected if gaps
stay smaller than 1\32" or .032". The gap will widen a bit in wear in,
but I'm pretty sure it's due to the worn cylinders and rings rather
than the gap.

Hey All;

   I pulled this 110hp reverse rotation engine out of my Meyers Manx
buggy a little over a year ago. I was out on the dunes at Pismo and
this engine started to use oil a little at a time but then over 5 days
it was blowing blue smoke like crazy out of each side of the exhaust.
I've had this engine in this buggy for about 5 years and have made
many sand trips with it and lots of driving back roads and trails. I'm
tearing it down (first time corvair teardown) and the compression
rings look like they have 1/8 inch gap (or maybe a little larger). But
my questions are with the oil control rings. I thought I would see
what the ring gap is with these, but these rings just fall through the
cylinder. Are they suppose to do that? Is there a spec for a ring gap
on the oil control ring? In fact, is there a spec for the gap on the
compression rings? Thanks for any information.
