replace valve cover gasket. there are 4 small rings that seal the plug ports. this keeps oil out of the spark plug port.
Chances are the oil return ports down through the cylinder heads are plugged and the oil is comming from the valve cover gaskets. The valve cover gaskets are not intended to seal completely under a pressurised system. so when the oil can't return to the oil pan and the pump keeps pumping the oil upward then it pressurizes the valve cover and forces the oil out of the gasket. try cleaning the oil return ports and change brands of oil. I prefer valvoline because it doesn't contain any parifine to clog the return ports.
Thomson cruises cover a large area going to all different and interesting ports such as Spain and France in the mediterranean.Also ports in the red sea such as Egypt.
There are different ways. One is that the 351w fuel pump bolts to the timing cover,the 351c bolts to the engine block. Water flows through the 351w intake manifold and does not on the 351c. The 351w has inline valves and the 351c has canted valves. The 351w has squared intake ports and the 351c has huge round ports. Hope this helps some.
The return oil ports are stopped up.
Check inside the front fender wells behind the tires.
Never have seen a bad head gasket on a 3800 engine. The upper intake will leak coolant into the imtake ports and a greedy mechanic will tell you it's head gaskets. You may need to replace your oil pan gasket with a felpro perma dry gasket, cost more but worth it.
If you are wondering why some intakes have coolant flowing in them, its because they have crossover ports, head to head, or single heads, they are cooling ports, also these ports cool the engine block around the cylinders. If you are asking the other question, that means why does the engine lose coolant thru the intake, that's because a gasket is blown.
No this is not a good Idea when there is a blown head gasket there is a good chance that water or coolant from the cooling system will end up mixing with oil from the oil ports this will lead to serious damage occurring to bearings etc.
45 degrees After Top Dead Center.... used in terms for motor cylinder timing...ports (exhaust,transfer,etc)
I had a Dodge Intrepid that was leaking fuel from the fuel injection ports, could possibly be the same thing.
The easiest method is to remove it, and plug the ports on exhaust manifolds and catalytic converter.
