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.
Blow down is done in the boiler in case level is high in the boiler
Blow bye in an engine is typically the force that comes from the mufflers, commonly referenced to as the hot rod era in the 50s. The "Blow-Bye" refers to the young girls that would stand behind the muscle cars and as the cars took off, the blow from the muffler would lift their skirts.
In injection blow molding starting parison is injection molded rather than extruded. In extrusion " " extrusion of parison occurs. There is three steps in injection blow molding: injection, parison and ejection. Tooling cost is higher in injection blow molding. one more, hot knife cut off the resins coming from heating zones before these goes to mold.
Well one of the main disadvantages of blow moulding is the amount of cheese that gathers up around the head when blowing
Slow blow Fuse that can withstand a heavy current (up to ten times its rated value) for a small period of time before it opens. Normally used for inductive loads like fans, transformers, etc. Fast blow Fast-acting fuses have no intentional built in slow-blow and are used in circuits without transient inrush currents. Fast-acting fuse opens on overload and short-circuits very quickly. This type of fuse is not designed to withstand temporary overload currents associated with some electrical loads.
What is the avearage cost to fix a blow headgasket on a 98 lumina
Yes You bet! it is probably the source of your problem.
does anybody know how this Bar's headgasket repair work?
Either a warped head and blown headgasket or a cracked head. An intake gaslet will also blow and let it in on a 4.3. I had it happen.
no you should not drive with a blown headgasket, water is now in the oil and will ruin the bearings etc.
your headgasket is blown
prolly a blown headgasket or results of a preexhisting headgasket problem. if your headgasket isn't blown or you fixed it before drain the contents and add more oil.
Sounds like a blown headgasket or intake manifold gasket. Sounds like a blow intake gasket to me...It happened to My 86 Mustang and my 96 Lumina.
? is vague. Even with a blown headgasket you will have some compression and it is usually the same in both cylinders
