    Default Tapping Noise

    Hi All

    I've got a 2003 1.8 Dual Fuel and for a while there has been a tapping noise coming from the engine. Its like the noise you hear if your car is short of oil. Ive checked the oil and its fine. Strangely when the car is still and i rev there is No noise at all so its hard to tell exactly where it is coming from... I only hear it when i drive. its noticeable in every gear no matter what speed im doing.

    This noise has been going on a while now, but i have no idea what it could be.. well maybe its the fact that I clock up about 1000 miles a week

    any ideas?

    It could be that one of the hydrolic "tappets" is weak and not holding oil as it should do. Has your motor got many miles on it?

    Does the "tapping" noise speed up when the rev,s do? and does it really make a noise when you first start it from cold, and get a bit quieter when the engine warms up.

    the tapping noise doesnt get louder, but does get faster as the revs get higher. It happens straight from cold and doesnt go away.

    It does sound like a hydrolic tappet that is at fault.

    It is not a five minute job, as it will be very difficult to pin point the "duff" tappet, it will be the best course of action to replace the lot, Whilst you are at it I woild put another cambelt and pully,s it they have not been done for a while. I don,t know of the cost but it will not be cheap, are you thinking of keeping the car for a while?

    It would be worth you getting it done then.
