I have an oil leak and it’s smoking not loosing a lot of oil just a bad smell and smoke coming from hood. I can see some oil leakage but not sure if it’s the valve cover gasket or rear main seal can someone help me out ?

 

Welcome to the Herd! Lots of friendly knowledgable folk in these forums.
Assuming a 2002 Ranger with V6~4.0L~SOHC Engine + 5r55e Trans + 1354 TCase + ...?
Looks like left ValveCoverGasket is leaking oil down onto the left ExhaustManifold; need a new Gasket.
Be sure to also renew your PCVValve every 33kMiles, at the rear of the left ValveCover;
a bad PCVValve or Cracked+Leaky PCVHoses can increase CrankCase pressure & cause OilLeaks.

yes sir thank you brother!!! I figured it would be calve cover gasket leaking on there I just wanted some other opinions. I did add blue devil stop leak and it quit having burnt smell but I am going to put new valve cover gaskets on

 

While you've got that left ValveCover off, is an opportunity to inspect the front left TimingChain guide (NotoriousFailureItem).
I'd also do an Oil+FilterChange after renewing the ValveCoverGasket,
then clean up the oil leak mess as best you can, so to better tell if you've truely fixed the leak.
Hope this helps.
