1987 4x4 22R engine blowing smoke uneven compression
 

1987 4x4 22R engine is blowing white smoke compression on #1, #3, #4 is 185 Compression on #2 is 160. Suggestions?

Head gasket / head likely compromised. Can try to torque the bolts by #2 tighter to seal, otherwise, head is warped. Resurfacing possible.

Also have to look at what made the engine overheat...usually that causes the symptoms you described.
