Omega 2.5 v6 cdx auto saloon about 1998 engine replaced about 2 y ago AFAIK.
I suspect because of blocked breather tubes and probable rocker gasket failure. Hence a build-up of pressure in the oil system, oil leaks, clean dipstick, a little mayo only on the oil filler cap. Runs happily in town as long as the dipstick is not pushed down, releasing the pressure, and oil is not lost.
120 miles on the motorway at 70mph and all the oil is forced out of somewhere underneath with the dipstick in. Dipstick out, town driving and no oil loss. No oil in coolant.
Got us back from B'ham to Worthing (174m) at 50mph max no problem with dipstick out, and just half a tank of petrol used, oil went down from max to min, sprayed out through dipstick pipe,and the engine compartment is now a little greasy. No loss of power problems, but slightly squidgy brakes under current circumstances.
Looking through your excellent maintenance posts, I think I can handle this myself, unless someone here thinks that a different cause is likely, in which case I would appreciate any comments.
Really need an estate, and have seen one also in need of repair with a sudden coolant loss - HBV problem maybe - any idea of approximate costs to repair?
thanks,
Chris
