- Q:I have a 2005 Dodge Durango and had problems with stalling. I took it into the dealer with warranty on it. They said the ECG Valve is busted and its unsafe to drive. Can you guys tell me what the function of this part is?
- There's no such thing as an ECG valve on any automobile. You're probably referring to the EGR (Exhaust Gas Recirculation) valve. It's purpose is to pipe a little bit of the exhaust gases back into your cylinders at higher RPMs to both promote cleaner emissions and to cool down the combustion chambers to help prevent knocking and pinging. However, in time an EGR valve can eventually get clogged with carbon which can cause it to get stuck open, which would cause an excessively lean condition during idle and can cause the car to stall. It then needs to be either cleaned (with plenty of carburetor cleaner spray) or replaced. I generally wouldn't say that a defective EGR would make a car unsafe, unless perhaps there's a big crack in it and exhaust gases (carbon monoxide) are leaking into the engine compartment/vents. I would, though, take a little extra care when crossing railroad tracks or turning in front of fast-moving traffic. Stalling there could possibly turn you into a coroner's curiosity.
- Q:I have an old trumpet valve stem that will not screw in the valve cap. I ordered a new one but I'm not sure how to remove the old one and put the new one on without doing anything that would influence the look and playing. HELP!!! Professionals are welcome and others. I don't have any professional technicians near by .Summer band is starting up so I need this FAST.
- I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.
- Q:I'm looking for a valve that can be electronically controlled to open and close with a diameter of 1.5'(inches) to 2'(inches) and this valve must be able to withstand 20psi. Any websites or listings of stores I can go to would much appreciated. Thank you

- Q:I have a curtis toledo compressor at my house. While moving it a helper dropped it on its side into the tank and broke off these 2 valves off the very top of the compressor. They had a copper line that ran off both of them and went over to the auto on/off switch, I'm guessing that's what it is. Where can I buy these or at least what are they called?
- The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
- Q:Hey, ive got a scooby and have a baileys dump valve that is a loud deep wooooosh sorta sound. What dump valve does the more high pitch sound? also they dump valve with the higher pitch seems to need less presure ta dump, mine needs alot of pressure before it will dump loud?
- if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
- Q:I just bought a brand new rain bird sprinkler valve with flow control and when I turn the valve on automatically or manually it makes a loud sound that resembles a muted horn and when I close it, it makes the same sound but thumps at the end. Is this normal? Or do I need to get a new valve?
- Provided you are talking about the valve that controls flow from the constant on of water to the sprinklers, that also cuts it off, the turning on is a groaning of the built up pressure (normal) releasing into the sprinkler line. The thump only occurs at the end when you close it because it's slowly cutting off the pressure. Its more pronounced in the sprinkler valves because you are dealing with greater pressure than say when you turn on a sink or hose, in fact you can nearly mimic a more muffled version of the sound by using a hose, and kinking it or using a nozzle head. Having installed 20+ of these working with my Dad on his rental properties, I can guarantee they are not silent. Unless water is spraying all over the place, I'm 98% positive its a perfectly functioning valve.
- Q:I have a 2004 yfz 450 and in the passed 4 rides (about 2 hours long each), one of my valves has stayed down and been broken when the piston came back up and made contact with it. After putting it back together the first time i checked numerous times to make sure timing, valve movement, and camshaft movement were all correct. and just 2 rides later (today) the same thing happened again. I have not began work on it yet so i do not know if it is the same valve. But has anyone ever had this problem before? Is this something frequent with yfz's or am i missing an important maintence issue? And can anyone tell me why this is happening? All help and tips are much appreciated!! Thanks!!

- Q:We have a 2008 grizzly 700...Lately when we run the 4-wheeler there is a ticking like noise (as is something were loose). I have been told by a few people that it sounds like the valves need adjusting. Does that sound like what it is? Will it cause any damage to the 4-wheeler if we ride it before we get a chance to adjust the valves?
- They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long

- Q:i have a 04 kia sadona i have been having issues with the van overheating someone told me to open the bleeder valve and let it drain then refill leave the valve open and if i see bubbles in the radiator than its a blown head gasket. is this true? is there a bleeder valve on this and if so where is it located? its not on the thermostat housing i allready replaced the thermostat.
- Yes it does have a bleeder valve, it should be on the side or in cooling hose, if your coolant has been low and you added you have air in the system, open bleeder valve till flow comes out smooth while engine is running and warm, when good flow is established and radiator is full close valve, should be good to go and will now be full and no more heating up.
