Making preperations for Spring repairs, and have a few questions...

Wondering if the pics show update or original drive connectors?

Valve Cover screws are tight, do i need to replace VC gasket?

Oil Pan look like sealant was used, and not gasket...???

Is their a bolt missing, or does the exhaust look normal ?

 

Those are new u joints in your drive shaft. Give them grease until you see fresh grease coming out at each cap.
You are missing a nut and stud from your exhaust, there should be 3.
If tightening the VC bolts did not help then you need new VC gaskets. Consider replacing your spark plug wires at the same time, because the VC gasket job will require you to remove the upper intake and that will make the plug wires easier to replace.
Degrease your engine, it is hard to tell from all the grunge there. It is easier to determine where the leak is when the engine is clean.
