As for the oil rings, I have a thought that may or may not apply. The last set of pistons I installed used two oil scraper rings separated by a sort of corrugated metal spacer ring. The ends of the corrugated spacer were supposed to butt up against one another but during my installation they kept wanting to pop over/into each other so the corrugations locked together. I spent a lot of time with my ring compressor trying to get things installed in a manner that I could still peek in there to see that the corrugated ring was properly in place. I still wonder if I got them all correctly installed.

: Based on the symptoms, oil rings are just
: a possibility. There is no way to check
: them without a teardown and visual.
: There could be a compression ring
: problem, which didn't show as low on
: the compression test because of the oil
: sealing it and showing slightly high. A
: leakdown test will show just how well
: sealed it is, at least the compression
: rings, if you have a tester, or can
: borrow or buy one.
: Hang in there, it's just a lump of
: metal...

: Hi again.
: After reading Oscars posting I must
: admit I'm a bit jealous. I can't get
: 2000 miles on an engine let alone
: 200,000
: As an update to my smoke issues:
: After removing the valve cover and
: rocker arm and taking off the valve
: springs on No.6 intake. Which was the
: worst cylinder. The valve seal looks
: perfect and so does the guide to stem
: clearance.
: As for crankcase breathing I'm just
: not sure what to think. I have never
: seen a TR engine with absolutely no
: blowby until this one. With the engine
: running and the filler removed from the
: valve cover there is nothing coming out
: the top. Either this is a really tight
: fitting engine compression wise, or
: there is no crankcase venting going
: on.. Oil does flow back to the
: crankcase though so it must be O.K.
: Also I restricted the external rocker
: arm oiler down to a .050 Diameter hole
: and it made no difference from
: unrestricted.
: It's looking like a tear down is in
: the works but I hate to do the same
: thing over and over again. The bottom
: line is why does this thing keep
: burning up oil control rings???
: P.J.
