Did the job today. Piece of cake. Removed intake manifold and the crossover pipe, which was caked with 1/8th+ of an inch of baked on oil from the crankcase vent, removed lines and replaced said parts. All went well and no leaks. It did take over two hours to clean out the intake and pipe and can just imagine what the intake side of the turbo looks like. I replaced the springs too because it said "renew" on the CD. The car started after bleeding the lines, however now it seems to do that diesel knock/chatter at idle a lot louder. It silences as soon as you increase RPM's. Even after warming on a short drive (5 mi.) it still seems a lot louder at idle, but runs just fine. Any ideas?
