By air intake do you mean the manifold or intake tube? Check for fuel and spark.

 

in the manifold, got both fuel and spark

 

Oil in the manifold is likely from a faulty pcv liquid/vapor separator, which wouldn't cause a crank but no start. Check your timing belt and timing, check for oil in the spark plug wells from a leaking valve cover o-rings, and for a worn cap and rotor (even though you have spark, that still may be a problem).
