My 1963 Nova was shooting out oil of the dipstick and PCV breathers, & drove it like this for 2 years until I did a compression test and was between 70-100 on all the cylinders. Rebuild Time. This all started 2 years ago so if you want to see part one that led up to this check out here:
Here is picture before disassembly. Note all the oil on the valve cover. I even installed oil catch can and put it on the oil dipstick.
Valve Cover off
Cylinder Head Off
Water Pump Off, Timing Cover Off, Flywheel, Alternator Off
Cylinder Head Dismantling
Out she goes!
On the Engine Stand Oil Pan pulled
Pistons and Rings Out
Old Flywheel is Toast
Time to send the block out to get Bored, Cleaned, and 0 Decked. I'll work on the head in the meantime. Dismantling complete.
