2003 Pontiac Grand Prix Question: oil leaking and sludge build up

We have been told the car has sludge and is leaking oil, slowly. how do we fix this issue -
Answer 1
The only way to confirm sludge build would be to at least remove the valve covers from the engine - has that be done? As for external oil leaks - The source of the leak will need to be determined and whatever seal or gasket is leaking will need to be replaced. I would not be uncommon for the lower intake manifold gasket to be leaking on your 2003 Pontiac Grand Prix. -
