hey all,
i have four questiona that have been on my mind lately.

1.  should the oil cooler be replaced after installing a new engine?  the
reason i ask is b/c, i read in bentley that you should replace the oil
cooler if engine has had excessive wear with a lot of shavings in oil.  well
my last engine had minimal shavings, but then breaking-in the new engine, of
course i got more shavings.  so all this on the same oil cooler, should i
replace it?

2.  how should you do a compression test.  with engine cool, i install my
tester in one plug hole, and with coil wire disconnected, i turn over the
engine and read the value.  is this right? or should i open the throttle all
the way when turning over the engine?  what is the step by step procedure?
incidently my readings were 140+/- all around and this is a brand new
rebuilt.

3.  is it okay to reuse coolant after draning it to replace water pump and
tstat?

4.  i have an exhaust leak at the elbow exhaust connection with pipe going
to cat.  i can see on a cold day moisture steam emitting from this
conection.  would this cause my co2 to be off, run rich or lean?  what else
could be off b/c of this?

thanks for any answers to these questions.
