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.

    How did you retrieve the dropped valve when trying to replace the seal. What tool did you use to fish out the valve stem.


    • Sorry there is no tool to pull the valve back out,,,,,if it is the intake valve you might take off the intake manifold and the reach inside with you fingers and push it back up,,,,if that doesn’t work then you have to take off the cylinder head sorry
