Compression Question...

[Peter Serwe]

My 1992 FSM for the Sentra/NX says it should be 178psi standard, 149
minimum, and a difference of no more than 14, your under the minimum, so
that would suggest rings or valves, add oil to find out, if it goes up, it's
rings, if not, it's valves.  Although if it stays down in 2 adjacent
cylinders, it may be a head gasket.

This is all according to page EM-12, anyway.

Have fun.
