Q: The automotive machine shop who is working on my Corolla head and block said that one of the valves was severely burnt. What causes burnt valves???: Usually a poor fuel/air mixture... running too lean etc... sometimes faulty timing can aggravate the issue as well. Exhaust problems are known to cause this issue in some cases... but so you know, there is a multitude of ways to burn a valve. FYI - Just replacing the valve will not fix the underlying issue... you will end up with the same problem. Once done, you need to start with your fuel and intake mixtures. - Good Luck!

Q: how could you make a valve or a system so that when it is pressurized, if enough pressure is reached in the system the valve will open completely and remain opened until it is close manually?I'm thinking about this in the context of an air powered dart gun, so that the firing mechanism is like a piston, and when a certain air pressure is reached, the valve that connects to the barrel will open and fire the dart: One thing you can do is get a pressure switch and a solenoid valve so that when whatever you are pressurizing comes to a certain level the switch will close it's normally open contacts and energize the solenoid which will open the valve. However as soon as the pressure level goes below the trigger level the valve will automatically close.

Q: Alright. The engine is a 7mgte. The clearances for the skims in the intake side is 0.20mm and the exh side is 0.25mm. What happens if i mixed the shims?: You can check the clearance with a feeler gauge of the correct thickness.If the gap is too big it will tick,idle will be rough,and throttle response will suffer.

Q: We have a 2005 GMC Sierra 1/2 ton truck that has a check engine light on. The dealer checked the code and he told us we need a new Evap Vent Valve and clamp. The cost is over 500.00 with labor being most of the cost. Is this diffcult to change out? Im a very mechanical person. Also he said it would be ok to drive for now but could cause problems down the road. ????like what?My wife is getting ready to take a trip in it, should it be ok for awhile? Dont have 500+ to spend on it now.: How Does Evap System Work

Q: My 4.0 L V6 2002 Ford Explorer has this plastic casing on top of the intake manifold...some of the hoses (brake booster, etc) are actually connected to the plastic casing, now how can i replace my pcv valve?: Try okorder

Q: What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.: There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.

Q: I just got my trumpet today.And its playing fine.Now its not playing.When i play im blowing air into it but its not going through.Its like im trying to blow air through solid meatel.and everytime in blow into it.The slide with the ring on it (sorry i just got the trumpet,im not really sure what the parts are) it keeps falling off.Its like its waay too loose.Help please: umm i'm not sure, cuz i play the clarinet but try tighning the mouth peciec and make sure your forming your lips right. then go to the place you bought it or you local music store to find out what's wrong. good luck and Merry Christmas!

Q: how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?: First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
