Yes I did clean as much as I could and I bought a uv light with the oil dye and I took my car for a ride to heat it up and the came back to check for leaks and nothing It didn't leak at all after 2 days I noticed 2 drops of oil and I try to find where they came from and it look like they came from a pulley maybe a seal from the crank? Or some seal I'm thinking that since it don't leak everyday actually I drove the car 3 days ago for about 4 hrs and I check today and still no oil leak not even a drop so it's hard to find where lol the bottom of the car has old residue of oil maybe when it heats up that's the drops that I see but I know in some point was leaking oil n still does like I said it was oil all over the engine when I bought it
