N62 valve stem seal

image Here a N62 engine,,,and we are replacing valve stem seals,,,as you can notice we have both camshaft  out for bank 2,,,, and both vanes units are out,,,,we the remove spark plugs,,,,we then add air to each cylinder one at a time,,,,when we add air to the cylinder,,,that helps keep the valves up when we release the valve spring to replace the valve stem seals,,,,yes I have seen a valve drop,,,,I have also been lucky enough to retrieve it without removing the cylinder head.image Here the other side bank 1 ,,,,which will be next,,,,I like to do one side at a time,,,I don’t like to have to many parts lying around,,,,I would rather complete one side then start on the other side,,,,at the dealer we are see less and less of the N62 engines.
