Default Oil leak

Oil leaking from front sides of the oil pan near engine mounts... what could it be?
I’m posting some photos hope they are clear... the leak increase when the engine is hot






TIA

Valve cover gaskets, maybe pan as well. Put a little carb/brake cleaner on a paper towel and wipe the exhaust side of the heads just below the outside edge of the valve covers and above your exhaust manifolds/headers so that it's clean and oil free.... take for a drive and get good and hot. Now check that area you cleaned off, is it wet again? If so, valve cover gaskets! Good luck 👍

valve cover gaskets most likely. what year and if an 86, does it have center bolts or perimeter bolts on the valve covers. cheers.

Get a UV test kit at say AZ, add die, test drive and use glasses with flashlight to locate leak traces.

That said, since wet down both sides check along sides just below VCs for oil; if not likely oil pan.
