I recently purchased a lawnmower with a 20hp Briggs. Unfortunately, I didn't know it was leaking oil.
I'm trying to determine where it might be leaking from. I assume that it's either from the cylinder, the crankcase or the head.
If anyone could point me in the right direction from these pictures, I would appreciate it very much.
It is fairly common for this engine to have a cylinder head gasket leak but not to the outside, inside to the push rod gallery. It is common for it to have a sump gasket leak to the outside under the right cylinder head as you are facing the cylinder heads.
