snip the drivel and name calling

Now, are you going to tell us in what way does an engine lose the oil on
the cylinder wall during the power stroke in the combustion process if
it isn't burned?

Certainly.
snipped more of your drivel and name calling

Now, ever hear of a burned exhaust valve? If the rings are worn enough
to allow oil past them, and the exhaust valve is *slightly burned*,
the oil will push out of the valve on any stroke where there is
compression.

A burned, even slightly burned, exhaust valve is not the normal case on
a new engine. An engine where the exhaust valve makes a good seal when
closed will still burn oil. The rings will allow oil past them even
when brand new. But let's examine your example above.

Who, and when was ANY statement made about the engine being "new"?

YOU did, or at least you made statements alluding to an engine being in
good shape not burning ANY oil. An engine with burned exhaust valves is
no longer in good shape. Man, you are stupid.

You're saying that if the rings are worn enough, they will allow oil
past them. Nevermind the fact that this is always the case. So, the
rings are allowing oil past them into the cylinder. The compression
stroke comes along and you're saying that during the compression stroke,
the oil that is in the cylinder is going to be squeezed out past a
slightly leaky exhaust valve and will be "consumed" as far as the engine
is concerned. Right so far? Ok.

Wrong so far, ok? Ever hear of valve stem seals? Ever hear of the
wearing and leaking?

But YOU said the oil was going past a slightly burned exhaust valve.
Keep your story straight. Of course oil can get past valve stem seals.
It's also burned when it does.

You do realize that not all of the "stuff" that's in the cylinder (in
this case, our air-fuel-oil mixture) gets evacuated during the
compression stroke, right? There is still some left in the cylinder at
the end of the compression stroke. So, in your example above, not *all*
of the oil that got past the rings will be forced out of the slightly
burned exhaust valve. Some will remain in the cylinder when that spark
comes and lights the whole mess off. What do you think happens to the
oil that didn't make it out of the slightly burned exhaust valve?

Again, valve stem seals. Easily worn out, very common.

You actually believe that ALL the oil, which YOU say is in the cylinder
during the compression stroke, somehow makes it out before the spark?
Just how does it to that? You're digging yourself in deeper and
deeper, and proving just how stupid you are once again, if you say
"worbn valve stem seals" can somehow get all the oil out of the cylinder
between the compression and power stroke.

Now that we're done examining your one way of losing oil above, let's go
back to the way the technical reference described. Please answer the
question: In what way does an engine lose oil on the cylinder wall
during the power stroke in the combustion process if it isn't burned?

Again, putting words in my mouth. WHERE did I say that the oil came
from the cylinder wall?

YOU didn't say that, you IDIOT. The technical reference from GM said
it. It says that the engine looses oil on the cylinder wall during the
power stroke in the combustion process. Do you care to disagree with
it? If so, just say that you know more about engines than GM and we can
finally show that not only are you a stupid moron, but an arrogant idiot
as well ... and finally put an end to this.
