I purchased my valver last week with aledgedly full Renault service history. and the last service is stamped as 2k before its current millage of 44k. However i decided to take it to my local garage who i trust and have done all the mods on my previous car for a small health check and minor service prior to taking the car to belgium and Nurbergring in Germany. The mechanic phones me up today hes had to have the rocker cover off as oil has leaked into the spark plug chambers he said the plugs were swiming in oil. Hes changing the clutch cable at my request only to find that the two types of cable they have sent are different to the one thats on and the only oil filter that will fit is one designed for a williams as the valver oil filters he ordered were to long. Not only that but the air filter thats arrived was also wrong. Whats going on? is it common for mix up in the parts for valvrs or have i got a swapped engine out of an r19 or williams? I am getting rather conserned the car is not as mint as originally thought should i be worried any things i should be checking?
