Can anyone shed any light on this or had a similar problem ?? Last week my 8v had a new head gasket. Head was skimmed and pressure tested. New water pump, new timing belt and tensioner and new dizzy, dizzy cap and rotor arm. Since I have had it back the car runs great until I stop and turn off the engine. I can then watch as the expansion tank just emptys. I have no leak from the engine or any pipes. I have spent two days checking for problems and can see the water comes back along the retuen pipe into the bottle and literally out of the overflow even though the bottle is not full. I then changed the throttle body and new expansion tank just in case. Last night I flushed the system and then run the engine warmed up with the heaters blowing hot with the return pipe disconnected. The water gets round and runs out the return pipe as it should. I then reconnected the pipe and the car ran great back home. Let it cool down and took it out with no problems. Stopped for fuel with no problem and took it home. Went to work this morning, came home dinner time and went back to work with no problems. Came home tonight and parked up and the water came out and the bottle emptied. Getting really fed up with the car now as the clutch is also noisy and was only replaced in Feb so is under warranty but the car seems to spend half its life in various garages and my patience is wearing very thin at the moment. Can anyone help ?? Also forgot to mention the car does not overheat at all !!!!
