Mine was making really bad noises yesterday and today, 2250 revs, so off I go to the garage, with metal images of valves slapping into cylinder heads It needed 1/2 a liter more oil, in it goes, still making noise, guys walks off comes back with a grubby looking screwdriver, presses the exhaust heatshield down, revs engine, noise is gone! I asked about the cambelt, 63k is what they say, my car is a 63k-something, guess what I'm having done on Friday!
