Hello Khaled, If you have oil in air, it means the oil is not completely separated from the compressed air before it leaves the compressor. You already changed the oil separator and minimum pressure valve, so that should be OK. Please check the scavenge line. This line runs from the top of the separator vessel to the bottom of the compressor element. It sucks out (separated) oil from the bottom of the oil separator filter. See this post: http://www.air-compressor-guide.com/blog/how-the-scavenge-line-keeps-your-compressed-air-oil-free/ Hope this helps! Cas
