I changed pushrod cover gasket, front gear cover gasket, and the front crankshaft seal. still have oil leaking from driver side of the engine. block looks dry under pushrod cover gasket. I can see oil on the side of the block below that. can't figure out were. what am I missing? would like to know before I start ripping this thing apart again.

 

Might be coming from the vacuum pump. Check where the power steering pump shaft goes into the vacuum pump for oil.

 

Have you checked Valve cover gasket or head gasket?
