Car listed above 'J' original problem - blown head gasket. Fix: both heads to machine shop for resurface and pressure checks/repair. Heads returned to service. Block to head surface checked for war-page. Visual inspect pistons and cylinder walls for cracks. New Fel-pro gaskets and head bolts and intake gaskets and bolts - all torque per Haynes manual for make and model year. Rocker arm bolts torqued per Haynes spec. Result: starts and idles little rough, threw p300 multiple cylinder misfire code performed compression check and no compression cylinder two left side (fwd) cylinder and cylinder three right side, other four cylinder's check 160-170 psi. Removed valve covers. Observed rocker arms and valves with engine running appeared normal. Loosened all rocker arms and performed rocker arm torque process again per spec. Same result no compression cylinder two and three. My next test will be a cylinder leak down test, mine is broken and the new gauge will not be delivered for a few days. In the meantime, could it be possible for the block to be cracked enough to have 0 psi compression? Leak down test is for sure next step, but anyone have any ideas?
