Intake valves are cooled by the gasses passing through them, exhaust valves are heated by the gasses passing through them and can be burned by overheating.

Why do intake valves usually last longer than exhaust valves?
They are not exposed to as much heat.
What retainer woes with the exhaust valve on a 305?
the fatter/taller one the springs might be different as well so use the shorter springs on the fatter/taller retainers if the springs are different. which retainer you put on a valve doesnt really matter to much. last week i put all the intake retainers on the exhaust valves and vice versa and my instructor told me that it doesn't matter
How long does it take to replace an exhaust manifold gasket on a 1990 jeep wrangler?
I last did that in an hour, but add another if its your first time. You need to remove the intake and exhaust manifolds since it is a dual purpose gasket. Actually, you only need to remove the nuts and pull them free of the studs, then you can remove the old gasket and insert the new one, you just need enough room to do that, then move the manifolds back over he studs. This is mostly true for the intake since the exhaust mounts to the same studs, but over the top of the intake, so once the exhaust is free you can let if drop to the fender, then all you need to handle is the intake.
How do you make your car exhaust last longer?
make sure your car isn't to low because the exaust might scratch the ground and brake
Does a replacement exhaust for a Honda civic aero deck 98 have to be supplied from a Honda dealer?
No, but an exaust from Honda will last longer than a reproduction.
What are the benefits of installing performance exhaust components?
It will improve the flow of exhaust coming from your engine. This will give you better gas milleage, more get up and go and will last longer. All of these things can also increase your cars value.
What is a egr valve and where located on a 1991 park ave?
EGR = Exhaust Gas Recycling. When running at less than full power, a percentage of exhaust gas is put back through the intake so that there isn't too much oxygen in the mix. Computer controlled engines can run far more lean than did their carburated counter-parts, thereby saving you and me a whole lot of fuel. But if the engine runs lean, too much oxygen can cause the combustion process to get EXTREMELY hot resulting in burned exhaust valves and possibly even pistons. Welcome to the world of the EGR valve. By controlling the amount of exhaust gas the computer is actually controlling the amount of oxygen, making the engine run far more lean and making valves last many times longer. If your EGR valve goes bad there are a couple things that can happen to your engine, one is bad the next is worse. If you're getting too much exhaust gas, the engine will run bad. If you're not getting enough exaust gas the engine will either run too hot or waste too much fuel. EGR valves on most GM vehicles are mounted on top of the intake manifold. They aren't usually too difficult to change, but many cars have a lot of "shroud" around the engine, to make it look "pretty". Sometimes that stuff gets to be a pain to remove. Whatever it takes, if the EGR valve is messed up, replace it at your earliest convenience. It will save fuel and possibly the engine.
How do you get more power from mk4 vw golf?
well first get a intake, full exhaust best one apr, r1 valve, light weigh pulleys and the last thing. more important is a APR chip.
In an overhead valve system what mechanism opens and closes the valves?
In most OHV systems, the cams are opened and closed in the following process: a camshaft is pressed into a gear which meshes with a gear pressed onto the crankshaft. The camshaft has protrusions which are offset from the center of the shaft so they turn rotary motion into longitudinal motion. The timed protrusions push two rods up at varying times (one rod controls intake, the other controls exhaust). As the rods are pushed up they push a lever that has a rod on the opposing side of the lever which is connected- either directly or indirectly- to the intake and exaust valves. The upward motion of the rods is reversed on the other side of the lever which pushes down (open) the intake or exaust valve. On one last note, the valve rods are encircled by a spring which returns the valve to the closed position when the offset cam protrusions rotate out of position.
