Hi guys ive been leak testing a york chiller and ive found a leaking head on one of the compressors. I tried tightening it up initially with no luck. Replaced the gasket today and it improved the leak but its still leaking. Anyone had this happen ? is there some sort of gasket sealant suitable for compressors i can try for this? i Will try to replace the gasket again tomorrow. And yes i have applied oil to the gasket on both sides. If i cannot get it to seal what are my options?
