[s-cars] Engine Rebuild Questions

[calvinlc at earthlink.net]

I totally agree with Dave, here.  The worst part about the engine rebuild is
having to do it at all.  Once you get past that point do it right.  Hone the
block properly, even get a tad bit oversized rings if need be after the hone
to guarantee the right piston ring gap when assembled.  DO your research on
the machine shop you choose...anybody can do a 350 Chevy, but a 2.2L
Audi....As far as the piston choices I have seen mentioned JE makes a heck
of a piston for just about anything with an internal combustion engine.
They are really top notch pieces.  I run them in my '72 Firebird.

1) Think  it's worth buying new valves, or are these 300k mile parts?
Cost here is  $365.  Not thinking it's much labor savings since valve
guides are  being replaced.

No, not unless the stems are heavily worn.



2) I'm getting quoted $360 for the main bearing set alone, is  that
reasonable??

No, way high.



3) about $500 total, parts+labor to remove, re-ring,  re-install
pistons...worth it?

An "in frame" rebuild minus the hone?  Wouldn't be my first  choice.  I
would
suggest you either simply replace the rod bearings and  recondition the head
(assuming there wasn't any crank journal damage), or pull  it all and do it
right.  I would not replace the rings without honing the  cylinders... you
could
end up with worse than you have now.  I would either  have it honed and
replace the rings, or skip the hone and keep the rings you  have.

Personally, I would pull it, have the block checked and honed (no ball
hones
please), and then reassemble using new parts.  I would not replace  the
pistons, unless the block can't take the hone (too loose)... which  is
uncommon on
Audi blocks with those miles.
HTH,
Dave
