<VV> Fix or rebuild 65 110hp engine?

[Mark Durham]

Paul, the jest of the problem can come from many sources, as depicted
by the other guys suggestions. My 102 had had a top, rings, pistons and
a good valve job before I got it, 15 years earlier and maybe 15k miles,
but just like you I had blowby, not to zero, so I drove the car until I
discovered flat cam lobes, but the rebuild was just honed barrels, cast
rings, etc, and the car ran out of steam with only 68k miles, so the
moral of the story is to check, check and check. My cylinder barrels
were so worn when I took a oil control ring off a piston, it fell right
thru. Do like frank said, check those barrels, pistons, and valves.

Folks,
I have a 65 110hp engine in my convertible. I have had this engine
since a complete professional rebuild 1980. Today it has probably
20,000 miles (since rebuild). It sat for long periods without being
started back in the 80s and 90s. It now has a bad case of blowby which
I have isolated to Cylinder #1 through a compression test (0 PSI on 4
different tests). I suspect broken ring(s) on #1. It took me from
Kansas City to Denver and back last summer and ran OK but it seems to
be deteriorating. It won't idle in drive now. I can drive it but have
to put it in "N" at a stop. So here is my question. I'd really like to
just fix the problem with CYL #1. By that I mean replace the rings on
that piston. What kind of problems am I going to introduce? What are
the ramifications of just doing the 'repair'. Comments/opinions
appreciated.
Thanks.
