Engine and oil are mixing. Runs great. I drained the oil and coolant then I top up the cooling system with water. Left it overnight then next day I took off the drain plug and 1litre of water came out. I'm thinking head gasket or oil cooler.

The head gasket could have a leak between a coolant port and an oil port. This wouldn't affect the compression and thus, it wouldn't run poorly.
