Oil, or coolant

I checked all 6 plugs today. 1,3,4 had some oil on them. I can't really tell what it is burning. i found out that my waterinlet is leaking, so that can be causeing the smell of burnign coolant. but the smoke is white. No water in oil.

White smoke means burning coolant. There doesn't HAVE to be water in the oil to mean it's burning coolant.

I've had plugs that I thought kinda looked oily, but in reality they were just normal plugs. On my 300ZX at the end it was burning oil and the oil was actually mixing into the coolant.
