I Clio Sedan 1.0 16v. 2002, with 120,000 km (recently bought) the car was failing to open the hood I saw that had oil leak near the air filter, to open the compartment air filter, I noticed it was full of oil, as well as 50% wet filter oil.
I spoke with a friend he told me I could be the intake manifold, it has something to do that? What could this be?
