ok C20XE engine i changed the vavle stem seals, cos i though it was burning oil, but the oil level keeps going down. It does not burn a lot, but i need to top it up after about a month and a half. There is no blue smoke, the head gasket is fine, im not loosing water.
does anyone know what it is, or do these engines burn a bit of oil
im using castrol 10w40 mag
