I have an oil temp guage and it never showed anything above 220. And I heard no
pinging. Dan and I were talking and he said I smoked a little at engine
braking for years. Couldn't a ring just give it up over time?

Ahh, well that clarifies things. Have you pulled the plugs? If you have a
burnt piston or rings that would be causing this much smoke the plug will be
wet on that cylinder. If the timing was too far advanced resulting in pinging
or it overheated you'll have a hole in the piston or a chunk missing. If you
had a full flow on it, it should have caught *most* of the crap but once it
plugged up it would just let the oil through; garbage and all. I don't know
the config you have on your filter so I can't say if it's full flow or not.
You can always look on the bright side of things with it burning oil it does
keep the mosquito population down.

I have a remote filter, I don't know if that makes it a true full flow, but
this engine does have an absolute load of miles and age on it. When I am
accelerating all is well. When I back off the pedal I get billows of smoke. I
have been told that is indicative of a "burnt piston". It could be crap in the
oil, it could be timing too advanced and it may be a cracked ring due to age.
I still need to do a compression test and stuff before I tear into it too
much.
I love my 1914 without the reduction boxes. I like to go far distances. I
like to average 68 MPH.
If I have to split the case and make a new engine I will NOT make T@P . Too
much money and too much time. Like I said, of course the "correct" thing to do
is to split the case and do a complete re-build. But if I take off the jugs and
check the heads and clean as well as I can and put in new cylinders, pistons,
rings, and connector rod bearings, basically everything I can do without
splitting the case, won't that put Murray on the road for years?
YES, I say gal dern it!
But I still haven't gotten a solid price on machined 88s with pistons and
rings.

You just suffered from a burnt piston. If I'm up to date on my e-mails,
that was it right? That means chards of aluminum/steel etc were floating in
your oil. And you drove it awhile. You should split the case and go through
it completely. A basic tear down with documenting the rod bearings etc. can be
done for reassembly if the parts are within tolerance. If the engine has over
70K miles on it, without a full flow filter setup, then it'll be time for a
rebuild anyway.
The other fact of nature is that you can get a longblock for about $1K or
less exchange. I know that might not have 88s in it but the differences from
87.5 to 88 isn't that much. Yes the wisdom out there is that the 87.5 cylinder
walls are thinner, which they are, but you can still get excellent reliability
from them.
Anyway, my $0.02.

I will need new cylinders, pistons, rings, all that stuff. At this
point I will probably only change out those parts. There is the philosophy that
I should replace the pushrod bearings and do a valve job and there is the
feelings that I should simply build a new engine.
I am old and tired and cash poor, so cylinders it is (maybe). Someone
told me that I could buy the machined 88s with the pistons and rings already in
them an I could simply install them at the wrist pins. Anybody know where I can
find these and the prices? I have a source here for the 88s and pistons but I
haven't heard a price yet.
For you mechanics out there. I have power loss and smoke on the
backstroke. Rings or burnt piston.
