Q: In aircraft reciprocating engine, if valve spring surge happen?1. Why happen?2. Affect to engine?3. Result?4. Feeling?: Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough

Q: My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?: Go to your local library, ask if they can get you the *factory* GM wiring diagram and service manual for your specific year/vehicle. They have a troubleshooting section that is usually quite good, with easy to follow flow charts. IAC is tied into the ECM in the way it handles air when you aren't using the gas...decelerating, stopping, when you start the vehicle (and different depending on whether the engine is cold/hot), etc. It will be stuck in one position now. When it starts to cause problems, you'll see them manifest in the conditions I describe above. If there truly no issues with the way it runs, then don't worry about it until you start to have problems. It's not going to destroy the motor without it. Not my cup of tea to know there is a problem, and ignore it, but then again, I'm me. You can rest assured though, if it were unnecessary, and saved GM one penny to not give it to you, they would not have installed it in the first place. :)

Q: my inflatable kayak has a self bailing drain valve. it says to close the valve in lakes and streams to stay completely dry and open it in oceans or mild whitewaters.whats the point of this valve? i WANT water to come in??: Self Bailing Kayak

Q: I opened the OPD valve on the BBQ propane tank and propane spray out, I have heard that propane should come out only when it is hooked. Is there something wrong with the propane tank?: Even if you open the hand valve, there is a pin that will slide into place and close the opening to not let propane come out when the tank is not hooked up to anything....this is a safety feature, if your tank is spewing gas without being hooked up, it will still function....it's just a little less safe. I would say tighten the hand valve after each use to be sure there wont be any accidents later. best case scenario, replace the tank.

Q: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.: Valves make a ticking noise due to: -normal wear -faulty lifter -faulty valve spring

Q: Can sum1 tell me how i can tell if my valves are in the right place?I notice there are holes in the valves, please explain how those holes are suppose to face to for each of the 3 valves?: Put the correct valve in the valve case. (There is usually a notch that guides the placement, but it is not always accurate enough.) Blow gently into the trumpet, (you don't need to play, just blow as you do to clear the spit valves). If you feel a resistance, rotate the valve until the resistance is gone. When there is no resistance with the valve up, depress the valve and blow again. There should be no resistance there either. Repeat with each valve.

Q: 1999 Mercury Cougar in awesome shape no engine problems, and has just under 86000 miles. I bought it recently and the check engine light came on out of nowhere and I realized It was an EGR issue the code was p0401 insufficient flow. I had a mechanic replace the solenoid valve as well as clean all of the carbon gunk off the valve and the light was off, then suddenly POPPED back on, making me really nervous and kind of upset. So today I had a few errands to run and I said I wasn't going to go get it read again until tomorrow, and it just Went off. So Is the car just very sensitive to things and is that why it goes on and off? Or is something wrong? I'm a student who really wants to keep this car nice like I bought it.: The EGR= exhaust gas recirculation valve is a controlling device to allow inert gas into the engine at cruise. The tube below it supplies the gases and the valve directs it into the engine. Any where within this assembly carbon can build up and get lodged in the pintle of the EGR valve. Some times it is the valve and a vacuum test of the diaphragm will detect failure. Keep in mind that there are two versions of the EGR valve Positive and negative pack pressure and the test is different for a positive back pressure style valve. A flexible spring rod with a scraping device at the end wil really help in the cleaning of the tube and passages. Don't give up , your on the right road.

Q: Exhaust valve opening (EVO)Intake valve opening (IVO): HI You answered it your self... exhaust valve opening (EVO) is when the exhaust valve opens.. and the same for the intake (IVO).. When the EVO happens the motor pushes the exhaust (burnt fuel) out of the motor when the IVO happens it sucks gas into the motor to get burned and make power.. Exampe of a 4 strock motor. 1) piston goes down , sucking in air and fuel (IVO) 2) piston goes up compressing the air and fuel spark plug fires ignighting the fuel 3) piston goes down turning the crank powering the car from the explosion of Fuel. 4) piston goes back up pushing the spent fuel out. (EVO) then repeats. On a 4 cylinder car this happens 4 different times on an 8 cylinder car 8 different times and on 6 cylinder car 6 different times. When one cylender is firing another well be coming up to push out its spent fuel and another well be going down drawing in fuel and so forth.. good luck tim EDIT IVC = intake valve closes EVC= exhaust valve closes

Q: It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.: There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.

Q: So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks: To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.
