Hello, I have joined this forum as it is very resourceful and everyone is very knowledegable about the Volvo! So I have a 2000 S70 GLT SE 2.4 Turbo that I am working on and it has and oil leak out of the intake camshaft seal and badly blows out a thick stinky white smoke while running. I cleaned the PCV system and am replacing the camshaft seals. I had loosened the rear camshaft sprocket only to find out that it's not on any kind of grooves or teeth and now I need to figure out where it belongs so I can out it back together. The rear exhaust sprocket does not look like the front intakes cam sprocket with just three bolts. The rear exhaust cam sprocket has a Torx cap over another Torx bolt that holds it to the cam. Any ideas and input would be very helpful and apppreciated Thank you
