Tapping On 1997 Alfa GTV TS 2.0
I have just bought a GTV, it had been in storage for four years, had the cam belt changed just before going in to storage, on the test drive and the 60 mile journey home it was just beautiful to drive, two days later a tapping sound from the engine appeared, this happened when the engine was cold but after about 5 miles it returned to normal, if you leave the car for about 30 minutes and start it again the tapping returns.
The is no loss in performance/power, I have looked through the forum and nothing quite matches what it could be, some theories state that if the oil had not been changed after the car had been left in storage it could cause blockages and thus explaining why the noise went after once the car was warm. The person I bought it from (a dealer) promised me the oil had been changed as had the oil filter, but the stated that someone had done the job for him, so you can never tell, having looked at it myself the oil is certainly a darker shade and I would wager the oil filter was not changed and it is rusty and very old looking.
The previous owner is in hospital so I cannot see exactly what was changed in conjunction to the cam belt until we get the service history from him, but it would be shoddy and a waste of time if the variator had not been changed.
I am guessing that the new cam belt would need to have been adjusted after ???? miles and wonder if this could be the cause of the problem.
People mention the "diesel sounding engine" I am none the wiser and I have had GTV's previously and every one I have looked/owned sounded a bit diesely to be honest.
There are horror stories about shredding belts, I personally do not think that is the issue here, but can anyone offer any advice what to do, I am not going to drive it anywhere as a precaution, I am very short of money at the moment so I am not going to go for the scattergun approach of throwing money at it until it is right.
All suggestions greatly appreciated, I did know what I was getting in to when I bought an Alfa, but love is blind !!!!!
