Adrian,
Did anyone ever answer you on this? If so, hit delete now.
Whatever your compression is, if it comes up 60 lbs. or 33% with oil in the
cyl. then your rings are well worn. Except: If you put too much oil in the
cylinder you'll raise the compression artificially, because you're taking up
a lot of combustion chamber space with oil which doesn't compress as much as
air. Try it again with a teaspoon of oil instead of a tablespoon.
If you're lucky it'll just be valve guides (or seals), but I'd start saving
up. It doesn't sound so good.

Subject: Rebuild question
Hi Folks,
Oil consumption is now 80 miles/quart. I can now see smoke from the back
when driving - not like a big plume of smoke, sort of like a haze. I
imagine I'm dripping a fair amount out as well.
Here's the funny part though - compression readings are 155, 155, 156, 155.
That's pretty darn good, isnt it? After adding exactly one tablespoon of
oil they go up to 210, 195, 205, 180. (1275 Midget, BTW) That's not so
good, is it.
Could I get by with fixing up the cylinder head and looking for leaks down
below? Or is it full time engine rebuild? Oil pressure is very good so
I'm kind of reluctant to attempt pulling the engine, etc, etc, etc.
Advice much appreciated. Adrian
