When I found the leaking oil.I cheaked the spark plugs. They look like they have a carbon deposit. Thats what the repair manaul says by the picture it has.

eh, spark plugs always come out a bit dark. They would have to be pretty messed up looking to have a problem, but check to see if you can match what tehy look like to your Haynes or Chilton.

Yes but you will need to only block off the egr port on the manifold and let it suck in engine bay air. If you take the whole assembly out you will have a code being thrown. Unless you have hp tuners to disable that code. Most guys just block the port on the manifold then attach a little air filter setup on the end of the egr tube and just suck in cool air.
