Ihave a discovery 2 when the car is ticking over rev the engine i the sound of water gushing through the dashboard ca n any one help thanks phill

this sounds to me like your corolla,s battery might need to be tested . i would recomend taking the car to a battery centre for a good inspection

The water gushing in on passenger side, is probably antifreeze, check that the heater core isn't leaking. If it is gushing try and capture some of this water and and see if it is antifreeze or just water. If antifreeze then it's the heatercore if water the. It's from the a/c

The oil light is pressure not level. The noise at top of engine is most likely a valve tap. The oil isn't circulation through engine correctly. The problem could be a bad oil pump. Be careful driving the car you could cause major engine damage.

It sounds like you need to heck your transmission mate.I had the same problem with my A4,B6 2.oltr automati as well.The transmission centre on 97564224

Air can get trapped in your heater core. Sometimes you can use a floor jack and raise the passenger side of the vehicle, start the car and leave it running until the coolant cycles and the fans come on then rev the engine a few times to 2500 - 3500 rpm and let up. If this won't push the air through then you may have to remove the upper heater hose while the engine is running and let the air out. Probably a little harder than it sounds. I believe there also may be a coolant bleeder at the top of the intake where the coolant flows to the radiator. Crack that open with the engine idling.
I hope this helps.

This is going to sound a bit far-fetched, but I've had a similar problem with a '93 discovery... Turns out the problem was water in fuel tank.

its the capasator needs replacing you blew it up.

try cleaning the petrol cap. it breaths round the key hole. i boiled mine. sometimes if there is not enough air in the tank. pure fule goes into the carb. and makes the car race. take fule cap and boil it in water. you can use steradent in cold water if you prefer. muck gets stuck in them.

You have an air leak in your coolant pipes under the dash.
There is air in the system.
When the engine is off the coolant is dripping onto the carpet.

need to replace the fuel regulater, located in engine bay.
