Omega Owners Forum - Oil in water.

stevi1 Newbie Offline Posts: 12 Drives: 3lt mv6	Oil in water. 20. Aug 2011 at 13:55 Hi was driving my omega mv6 this morning and the oil level warning light came on. I pulled over and notice the water bottle full of oil then the rad pipe blew off and oily water went everywhere such a mess. Do you think this would be the oil cooler? Was alot of oil in the water must of block the rad?

Will i have to go to vauxhall for the oil cooler or will a motor factor be able to get them. can get a good second hand engine running perfect but maybe its oil cooler would be no better. What is it that goes in them?

Later ones were stainless steel, but the metal corrodes in them, its a radiator sitting in water basically, if poor coolant maintenance is done, it will start to let oil escape into the coolant. Vx is best place for parts, replacement engine will have unknown history, the oil cooler can just as easily fail.

Oil in water is oil cooler failure, you said "rad pipe blew off" - Is that not the source of the leak?

the pipe was refitted before i put the water in but then maybe the rad and stuff is blocked with oil so cant circulate.

Without oil in the water I would say maybe but I doubt that the HG would cause the pipe to blow off. With oil in the water defo oil cooler as the coolant and oil passages are set in a way that HG failure would not cause oil in the water.
