I took off the
exhaust manifold and, sure enough, two of the seals are shiny and spring back
about 1/16 inch when you press them (hard). The other seal is intact, but not
shiny and only springs back maybe 1/32 when pushed. It IS moving, so it's not a
stuck seal - sounds like the side seals are gone. We'll know more when the Mazda
guy gets the engine comes apart......
Oh man, another kick in the
groin... Sorry to hear about
that.
As Ed said, if it's not shiny, that's the
problem. There is still a slim chance that the groove has some carbon or
something that's formed around the edge, and is keeping the seal from springing
all the way out. I would absolutely spend some time trying to free this
apex seal, before even thinking about having the engine torn down. What
have you got to lose?
If you do tear it down, go ahead and order
some of those seals that Tracy's selling Turbo Boy. I wonder if he would
warrantee them against "John Slade"... Nay, he's smarter than that
:-)
