Finding TDC (sorry, a bit off topic)

[Steven Ciciora]

Hope no one minds, but I came to the sudden realization that I don't know
how to diagnose cars.  And how can I expect to 'performance tune' if I
can't even get a stock car back to stock? (hence the very weak gmecm
tie-in).  O.K., I'm going to try to do a leak down test on an 1989 Chevy
Beretta, V-6, manual trans, Front Wheel Drive.  I looked in the service
manual I bought from a dealer, and couldn't find directions on how to find
top dead center.  Any suggestions?  If no other ideas, I plan on taking
the valve covers off and moving the crank until I see both intake and
exhaust valves closed, and not moving.  I imagine if I don't get exactly
top dead center, filling the cylinder with compressed air is going to make
it move down, so I'll keep my fingers away from the belt, and mabe see if
I can 'lock' the crank from moving.
Thanks for your time,

- Steven Ciciora
