This is usually one of the areas that people tend to when they are replacing the belts or water pump These seals will leak eventually In addition, it is a lot of work to get to them, so it really is a good. Extending the life of our porsche 944 turbo by fixing some annoying oil leaks Yep that’s the cam tower, it has a total of 5 seals including the gasket between it and the head The one that really leaks a lot is a tiny donut seal behind the cam pulley, that will spill oil on the front of the header and down the front of the engine.
The source of the leak is most likely from the camshaft housing, or one of its gaskets and seals When you replace the main gasket between the housing and the head, also replace the seals at the front end of the camshaft. I'm not sure why but, porsche used a cork gasket on the rear cam housing cover They are notorious for leaking and usually start giving problems shortly after the car has 50,000 miles on it. Oil leaks on the exhaust manifold from the valve cover area was a real learning experience for me on my 1983 944 I spent a whole bunch of time trying to get this to seal before finally going to my local independent porsche mechanic/racer
The car is an early 83 944 (built 3/82)
