New to the forum and looking at all things 18T related. I see that the 18T has a oil/sludge issue. My car is 2003 model,bought a 6 months old from main dealer with 1500 miles on clock. The car as now done 18,000 miles only. In that time i have used the long life service and never on time. I have just got the cambelt and all neccessary parts changed due to age ,by a good independent. I now have worries on the sludge issue i read here. I read not to flush but to do a couple of oil changes first.Apart from that what is the "PICK UP" that needs to be addressed.What parts need changing?
