FWIW:  The owners manual to my friends 1991 Nissan Sentra GXE (1.6
16v) says that (paraphrase) "light engine knock or pinging may occur when
your engine is under heavy load, such as climbing a hill.  This is normal
and actually enhances [economy/power]"  blah blah, your engine is designed
to tolerate this for brief periods, blah blah.
