Double check it's had the oil pickup seal done on it at that mileage. If that goes it will kill the engine. Boost pipes can wear/split pretty commonly on these too so double check those. Other than that, usual stuff of service history / rust underneath etc.

Fixed, got bolt direct from dealership. Part number attached in case anyone gets into the same situation.

Best guess (I'm no mechanic) is number 8/10 on that diagram, after doing a quick search on the code

Had a bit of a nightmare and snapped the banjo bolt on the turbo oil feed (Turbo side) when reassembling after doing a cam cover gasket change. Garrett 822072-5004S turbo on the B20 engine. Anyone able to help with the dimensions of the replacement bolt and any suggestions where I can get one asap please.
