i figure there is a > 75% probability that removal of an oxygen sensor
from an old (probably original) exhasut manifold - even heated up from
driving or a blowtorch - will cause any of the exhaust manifold parts
to need replacement. is this reasonable to expect? i.e. should i be
prepared for welding, new manifold parts, etc.?
if not, what tricks are there to preserve the manifold when removing
the oxygen sensor?
