My series 1 is blasting oil out of the dump valve. It goes everywhere. i took the dump valve off and it's still using loads of oil the underneth of my car is covered in oil. it's not the turbo as i've had mine rebuilt recently. i was told to take the breather hose off that connects to the bottom of the metering head and put it in to a bottle and see if oil collects in the bottle and it does, which points to the engine breathing heavy. which also points to the piston rings. thing is my car does not smoke at all and i'm told if it was a piston ring then it would smoke it's head off so does any one have any ideas.

Thanks alot
Paul
