  1. now i know its probably the head gasket but before i tear it down i want to make sure, car runs descent, has water in oil but cant find any oil in the cooling system. seams like if its in one it should be in the other. test ive done 1: compression. carries 210 psi ( with my gauge) on all 8 2: cooling system leak test. found that the radiator has separated at the seam, small leak. when i bought this car the intake was completely off and i was told it just needed a starter and ignition switch, it needed a starter because he was gonna run a strait push button switch to it to start it because the vats had the starter disabled and he jacked up the ignition key lock trying to remove it to put another in thinking the key lock wasent reading the pellet on the key, turns out the vats module was bad, replaced that and put everything back together and bam, car started right up, worse case scenario ( blowed head gasket) now here is what else i found, there is water in the oil, i did change the oild and filter but dident really flush the system, dident have time to at that present time, wife was griping about wanting her spot back in the driveway, so i added the oil and moved it to the side yard, anyways the oil is still milky, but i dont know if its from the residual milky oil that wasent flushed, ( not sure how much water it would take to contaminate 7 quarts of oil to the point of making it milky) or if it has a head gasket leak, i drained the oil and placed another pan under it leaving the plug out and put the cooling system pressure tester back on it and was thinking that if i pressurized the system that water would find its way thru the engine and i would eventually see water draining from the pan at the plug ( correct me if im wrong) 2nd scenario ( stupid people) when i was looking at the car the seller said that his wife just washed every bit of the car, i did find a little water in the intake valves before i re assembled the intake ( yes i blew it out) now i dont remember if the oil filler cap was off or not but the pcv valve and tube was in the trunk so im thinking if she sprayed under the hood of the car it would be possible for a sufficiant amount of water to get in the engine thru the pcv hole in the valve cover thanks and any help is appreciated
