Just looking through the receipts of my car, cos TAX is due at the weekend I found the receipt for a head gasket, 9 valves and a cambelt. This was at 42k miles, so some1 obviously forgot to change the cambelt regularly.

I have had the head gasket done since I have owned the car, since the leak appeared to be coming from there when all this started 6 months ago.

So the car is now on it's 3rd head gasket, had the head skimmed twice.. is this healthy?
