Hi and Thanks in Advance?

Thanks, I have a 1993 Missan Maxima with a slow water leak SOMEWHERE
around the engine. So far I can't see WHERE (origination point) the
leak is coming from. Just too tight to see under there.

Two Questions:

1) Is there a most common place for a slow leak to occur on this car?

2) Is there a TRICK way to pinpoint WHERE the leak is coming from?

Thanks
Gene
