[Shotimes] Throttle body gasket

[Mark Mucher]

I'm trying to track down the source of my crankcase pressure problem (as
evidenced by oil leakage and seepage) on my '90.
 
Paul N. suggested removing the throttle body, cleaning it out, and checking
the flow of attached hoses.
 
Problem is that I can't find a new throttle body gasket locally today.
 
Can I (try to) reuse the old one?  Or should I wait until I can get a new
one?
 
Any other suggestions for PCV issues?
 
Thanks in advance,
