All that's being checked too. They are literally working there way down until they find something obvious. Their even replacing collets. Going to be a brand new engine pretty much lol. So the bill has racked up to about £1100 all in. Which isn't too bad for 4 days labour. Every gasket/seal/washer piston rings, big end bearings, collets, seals, water pump and cambelt, oil pick up pipe, and haldex oil changed. Turbo is being inspected too. So hopefully it gets sorted. Well if its not them I'm screwed haha. I shan't be going any further power wise tbh.
