One more question, is a special socket required to pull the injectors? Thanks P.E.Haiges I should move that injector arond and see if the noise follows it, I'll try that. But at 233k they could probably be replaced so I will do them all. The glow plugs I already have so they will be going in. This will be a good oppertunity for me to clean out the intake manifold, and break the egr.
