I have a 2003 Vectra auto with the 2.2SE petrol engine with nearly 90K on the clock.
When I dip the engine oil I allways get a small amount of white sludge on the bottom of the dipstick. I have changed the oil and filter twice with recommended vauxhall synthetic oil but shortley after that the sludge returns. I have kept an eye on the water and engine oil levels in case the head gasket has gone but the levels are staying the same over 1000-1500 miles.
Is there any kind of rescurculation system fault on the engine that will cause this to happen, or anything I can do? I have taken the car on several 1.5hr runs to just in case its just the short runs I do (about 20 miles a day). Any help would be appriciated.
