Trouble description: MAC lube oil turns opaque and milky within days of renewal.

Main air compressor # 2 lube oil color changed so we renewed the oil but within days the new oil also became milky in appearance.

Important points:

- No maintenance work was carried out prior to when we started noticing this issue.

- We didn't test the oil for water but the oil remains milky state even after a long time.

- LO pressure of 2.5 bar has not changed but we get Low LO pressure while starting sometimes.

- There is no attached Cooling water pump in this compressor (direct from LT system)

Measures taken:

1. Unloader drain interval reduced to 10 mins

2. 1st and 2nd stage drain pipe to unloader checked , passage is clear.

3. Cylinder head gasket is renewed
