I was at the car wash yesterday, and I noticed when I lifted the hood that there was a small oil leak on the left-hand side engine and was trying to figure out what might be the cause of it. What do y’all think it could be? at first I was thinking exhaust manifold gasket because on a cold start I do hear a little bit of a tick so it might be a bolt that got snapped in half due to heat of the iron cast header.

I’m trying to figure out where I’m leaking oil. I recently just changed the valve cover gaskets because I figured that was the cause of the leak what do y’all think it could be?
