You could have a broke ring, cracked piston or the aluminum between the
rings could be broke and or pushed out. The later is what happened to an
engine were overhauling.

Subject: [DML] Houston, I have a (compression) problem


So while I was wasting time waiting for the penetrating oil to work
into the bolts holding down the coolant Y pipe, I thought it might be
a good time to check the cylinders for compression. My results are
less than promising.

Cylinder#    Comp 1st run    Comp 2nd run    Insulator Appearance
    1            140             155            Black and sooty

    2            115             125          White like brand new

    3            107             120               Tan

    4             40              40       Tan and wet with wet
                                       black but not oily electrodes

    5            140             140              Off-white

    6            113             115                Tan

Is there any chance the the # 4 clyinder has stuck rings and can be
brought back to life?  I remember reading about putting some oil in
the spark plug hole and that help you figure out if it is the rings
or valves.  Any ideas??  or should I convert ot an electric motor
