: I got the engine torn down tonight with
: the exception of scraping off some seal
: residue and removing a couple of core
: plugs.
:
: There is no point in my trying to post
: a picture of what I found wrong as it
: would not be possible to see. You have
: to feel it.
:
: I did indeed squish the piston on the
: side towards the intake/exhaust. Both
: compression ring glands were collapsed
: just enough to make it difficult for
: the rings to float and find their
: center in the bore. If I were on a
: super, super tight budget I would
: probably just fit new rings and turn
: the pistons in the lathe at work to
: restore the gland width.
:
: However, the rest of what I found says
: that would be a wasted effort. There
: was a substantial ridge at the top of
: the bores and my relatively new big end
: bearings were scuffed badly... some
: through the top layer into the copper.
: There was some modest scoring on the
: rod journals on the crank also. The
: main bearings looked fine.
:
: My crank end float measured 0.008"
: which is what I measured 4 years ago.
: It's right on the high end of the spec
: in the factory manual so I will buy new
: thrusts when I order the rest of the
: parts.
:
: My plan at this time is to take the
: block, crank and pistons (with rods) to
: the shop (hopefully tomorrow). I'll
: obviously have them tell me what to do
: about the bores/pistons. I'll have
: them check the crank and advise me on
: whether to polish the journals or grind
: them. I also want them to check that
: the big ends of the rods are still
: round and sized correctly.
:
: I wasn't planning a rebuild but after
: peeking inside this engine I think it
: was probably coming due soon.

: Doug you should be able to move the
: piston side-to-side a few thou when @
: TDC. If the top ring is jammed in the
: groove it won't move.
