There should be flush kits available, I used one where I had to pour into a separate bottle and pressurized with shop air... flush through, add oil to accumulator if needed, install orifice tube. Make sure to drain oil from compressor and charge with correct amount and type of oil. If possible replace any O-rings at the block fittings to help prevent leaks. Pull vacuum and charge if no vacuum leak is found.
