Hyundai Repair: oil leak, sonata 2, oil leakage

Question
Huyndai Sonata 2.0 1996.DOHC engine.
I'm having problem with oil leakage.
There is oil leakage under the inlet manifold.
I thought it was coming from the gasket between the cylinder head and the cover above the cylinder head. I changed this gasket but it did not helped anything.
Under the inlet manifold there is a lot of oil.
The former owner did not change the air filter it was totally stop in the old one. The new air filter seems to be a lot better. I found some oil in the hoses between the air filter and the inlet manifold. I think there is some problem with the underpressure. Is there anything to change, any filter, any non-return filter or something else.

Thank you for your answer

Answer
Hi Petri,
First , you need to know what type of fluid leak you have; Motor oil? Trany Fluid? Brake fluid? Coolant?
If you think it is motor oil , clean the area real good and add engine oil dye. After couple days check the area with dye-light. I am pretty sure you will be able to locate the leak.
