Not another general...help, sludge! thread.... Picked the avant up on Friday and it's sat on the drive all weekend till being dropped at garage this morning. True 54k (every old mot etc) miles with no bill for cam belt so spoke to previous owner who confirmed he's not changed the belt since he's owned it which was around 1.5-2 years old I went for the low mileage car as it had a great spec, definately original miles (history and all mots) and just as importantly a bill for £1,100 back in Dec'11 (8k miles back) for a de-sludge (new pick up, oil pump, flush and full service etc) - previous owner also confirmed no problems since. Anyway, car in for the cam belt and had a call and the oil sludge I'd assume had even affected the hydraulic/manual tensioner which had seized (its hydraulic and oil fed) - add to that the impellor had partly broken (orig plastic type) - all not a problem as has been caught 'just' in time (impellor bit recovered etc). Garage said either it would have overheated soon or the tension on the belt would have gone ...... As well as the cam belt, tensioner, water pump i'm having the car flushed then refilled with 5/40 quantum (he said he'd use 'DT' flush which he's never heard any problems from - add to existing oil, run up for half hour then drain and re-fill with new oil and filter). On top of this i will do another oil change from garage during easter break then regular changes each six months (around every 6k miles). Could be worth also checking cam belts if you have problems with sludge in the future (perhaps this car is a one off)? Any thoughts? Extra £200 on top of the bill but piece of mind and looking forward to enjoying the car (and getting a few new oil service stamps in book over next year).. To do: Refurb wheels; Possibly new clutch before France/Spain late summer (it's very high and don't want any hassles overseas - is this £350 or £700 depending on DMF replacement and is that likely requirement at 54k miles....guess it could be); Replace the 4th tyre with a Goodyear Eagle F1 (all others are pretty new and F1's); Either a mop or spray of front wing to get rid of some deep'ish scratches from washing (suspect some grit on sponge at some point).
