The camshafts on the 944S do NOT rest on the bearing surfaces behind the #4 cylinder. In the reasssembly procedure discribed in the Porsche Workshop Manual, it says to put two bearing seals (they look like round rubber plugs about the same diameter as the cam journals) into the area that is machined as if it were intended for the camshaft. The seals in the picture are definitely different than the plugs that go into the bearing bridges and are visible from either the front or the rear of the engine. The problem is that I cannot locate a part number for these bearing seals, and know one seems to know what I'm talking about. I'm worried that if I do not reinstall SOMETHING into these normally empty bearings, the oil delivered to them will flow unimpeded into the head, potentially filling it at high RPMs. I don't recall removing anything when I dissassembled the head, but I bought the car after someone unsuccessfully tried to repair it following an overheating episode.The head has been professionally refurbished and everything else looks great. How do I deal with the bearins seal question? Do I need them or not? And, where would I find them?
