steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
Engine back pressure is a common ailment in faulty engines. It is when the exhaust sends the power to the very back of the vehicle, instead of through its engine.

I interpret your question to be: Why do head gaskets (on an engine) blow-out? There can be several problems: The engine head itself might have been tightened incorrectly (misstorqued). This can happen when the engine was first assembled or after a repair. When this happens the pressure on the gasket in not even and not tight enough in places, so the gas pressure of the engine finds the weak spot. The gasket might be defective. Most gaskets have multiple layers bonded together. If the bonding is not correct or a gasket layer was misscut, again, the gas pressure will find the weak spot. The engine head or cylinder block could be warped. This can happen when an engine severely overheats. The two components will not bed the gasket properly and the result can be a blown gasket. The gasket could have simply worn out. They do have a life expectancy and require replacement when the engine ages.
The oil pressure sensor on a gas engine is on the back of the block next to the distributor.The oil pressure sensor on a gas engine is on the back of the block next to the distributor.
It is on the back of the block to the right of the oil pressure sending unit, if you are looking from the front of the engine to the back of the engine.
Most likely the problem is with the Pressure Sensor in the engine block.
Right behind the distributor on the engine block.
The location of the oil pressure switch depends on which engine the car has. On the 2.8L V6 the oil pressure switch is on the side of the block below the exhaust manifold on the radiator side of the engine. On the 2.5L 4 cylinder engine the oil pressure switch is located on the side of the block below the intake manifold.
dismantel head from the block and have both pressure tested seprately
On a 5.7 V8 engine, the oil pressure sending unit is on the back of the engine block next to the distributor.
Engine Oil Rifle Pressure Sensor 1 is located on the left side of the engine block, about 1/3 way to the back.
the oil pressure switch is on the block right above the oil filter and also where the oil dipstick goes into the block
on top of the starter of front of your engine block
Standing in the front of the engine, It will be on the top right rear of the engine block.
Standing in the front of the engine, It will be on the right back side of the distributor. It will have an electric wire pluged into the top of it and it will screew into the engine block.
