Hook up vac line , turn on and if you can hold on to motor and stall it it is 
weak.  It should jerk out of your hand.  If it doesn't, run some air tool oil 
thru it then heavier oil to reseal piston.  You might rig up a bottle to 
catch oil before it goes into manifold, although I haven't ruined any engines 
oletrucks is devoted to Chevy and GM trucks built between 1941 and 1959
