HI,
about 2k miles ago, i rebuild the tranny,(costly mistake, should have
gone used), old jrsc, and motor on a 95M-ed w/ a jrsc. the machine guy,
(excellent reputation and I have used him before), disassembled the
reciprecating mass did various machining, (10 over) and reassembled it.
he toldme the rings didnt require any break in and i slowly put the
car back together.
shortly after i got it re-registered, i had to do emissions and i
couldnt get it to pass after a different exhaust, timing, chaging
plug/wire, blah, blah,blah. now the car leaks oil from all seals, f/r,
everywhere, like the valdez.
i was hoping, (in a way), that i had done something bad or wrong but
after a leak down test, (47, 65, 67, 72), it seems it must be rings of
cyl walls. do you concur?
ok lets say you do. is the best option to pull the entire drive train
or could i pull the head and maybe just change the rings with the block
in the car?
this was the "biggest" job i have done and i probably know the answer. i
just hope there is an easier way i havent thought of :( i do feel good
that it does not look like it was anything i did worng but i still have
to deal with the situation.
thanks for your comments,
peter

Others with more experience will respond, but I do think it is next to
impossible to get to the Miata engine's bottom end while it is in the car. I
know PBC pulled my engine to replace the oil pump.

IIRC, the oil pan won't come off unless 1) the engine is removed, or 2)
the front subframe and suspension are removed. #2 is probably more work,
even if none of the bolts are frozen, and you'd still have to bend over
the fender to reach the engine, risking both the paintwork and your back.
