Timing Chain fun on an Audi Q7. Intense.

Here we have the rear of an Audi Q7 engine. This section requires the removal of the gearbox for access. So ultimately the complete subframe and powertrain needs to be removed. and then there is room to split off the gearbox and all of the associated intake and exhaust plumbing. If you look closely you can see some of the timing tool locking pins are fitted. This job started out as chasing oil leaks and ended in timing chain replacement as some ‘routine maintenance’.
