1996 Other Nissan Models Oil Leaks

Hi there,

If you are getting oil in your air cleaner, this is a sign of a problem with the engine, excessive crank case pressure will be carrying oil into the air cleaner via the PCV. Now you may just have a faulty PCV so may be replace it first, but if you run the engine and remove the oil filler cap and there is excessive pressure, you have a ring problem.
