Re: 3208 oil preasure
One thing to keep in mind with a diesel engine, is that they can "Wet Stack". This is a problem where the engines are not being run very hard or are sitting at idle for extended periods. What happens, is unburnt fuel passes through the exhaust. It then leaks out in areas such as between the turbo and the exhaust riser (if a wet exhaust engine) or other exhaust joints if a dry exhaust. It looks exactly like oil, and for the most part, is not something you need to worry about unless you are a neat freak. Generally speaking, it will cause smokey conditions at first that go away as you run it under a load. It also tends to leave oily deposits on the outside of the engine. Take a look at an old semi truck. Guaranteed to see an oily residue around the manifolds because truckers idle their engines all of the time. It looks like oil because of the soot, and since Diesel fuel has lubricative properties, it feels like oil.
Normally all it takes to get rid of this, is to run it hard. A diesel engine is only happy when it is working.
Sometimes though, if the engine is always under a light load, you can glaze the cylinder walls and start to lose power. This is something that a compression or leak-down test would tell you. If that happens, you can be sure that you are replacing rings and liners at the minimum. In other words, a complete overhaul. But, you would notice that the engines are very sluggish, and doesn't really have any bearing on oil pressure.
