- Q:I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
- well, is the car in good shape otherwise, like the tranny, suspension and the body?, if it is, then its probably wort a valve job, its cheaper then another motor.
- Q:Its stuck to an angle where the metal parts of the wheel block the air pump from letting it secure itself around the valve so i cant put air in, it all comes out the sides, i dont want to have to replace anything for i dont know much about bikes, but any solution to my problem? Thanks
- What causes the valve stem to get like that. is from riding it with an almost flat tire with very little air in it. . Let the all the air out of the tube ,. pull and tug on the tire to rotate it on the rim until the valve stem is standing strait up again. Then refill with air. But often when you ride with low air, it ends up making a hole in the tube.
- Q:Hi, I just got my 20 gallon freshwater aquarium yesterday and set it up today with the filter,water, pump,etc... I bought an AquaCulture 20-60 gallon double outlet air pump and didnt realize it had two valves. I only need to use one though ...what should I do??p.s. The bubbler thing that lets the bubbles out is a rectangle and its long but it isnt working in the middle of it...? would that be because of the double valve?p.p.s. the pump came with two check valves.Thanks, Sarah
- If the pump doesn't come with any method to shut off one of the outlets, you can combine both outlets into one by using some tubing and a T-valve. You can also use an air valve and some tubing on the unneeded outlet to dead-end it, though that method may be a bit more stressful on the pump.
- Q:I think I have a bad valve steam seals because when I start the car white-grayish smoke comes out of the back of the car. When let sit for 2 or more hours start car and smoke comes out everytime. Will a valve adjusment fix the problem? Thanks
- Well, it can only get from bad to worse, costing double as much everytime. For now if you leave it, you will need to top up your engine oil very often, and your fuel consumption will become higher as engine friction is higher and ignition sealing is poor (high blowby gases). This means also lower efficiency of the vehicle. If the weather is hot, the engine will have a higher probability of overheating after operating for long periods of time (say 3 hours or so).... but the real danger is if you keep it this way, your crankshaft and connecting rod bearings will start to scuff little by little, which might cost you a very heavy engine overhaul. My advice: send it to a technician now, as it will require special tooling to tighten the cylinder head, remove/install valve springs, and maybe some shim calibration if it is an old model. Valves must also be inspected, and their guides as may have worn out. Give to specialist, I say, unless you have the patience and spirit to experiment.
- Q:What's the safety valve (relief valve) type?
- The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.
- Q:The valve on my radiator has numbers on it to determine the amount of air/steam leaving the heating system. what number should i put it on and how would i determine it
- I would think the easiest way would be to put a thermometer on the radiator (with the bulb in the air flow), turn the heat on to one setting and record the temperatures each half hour for about 4 hours. Then, turn the adjustment to a higher (or lower) number and repeat that. That way, you'd know which way to turn to set it. Of course, the level at which you'd be comfortable would be found by trying different settings. Assuming the adustment is a valve, valves in the USA will open by turning counter-clockwise. Closing is, of course, clockwise. Hope that helps. EDIT: I received your email - I don't mind at all! OK, so you have only one valve for all the radiators. Without knowing anything else, I'd say you just removed the part called the bonnet (the upper half of a valve). It shouldn't matter which number it's set on if it's reinstalled correctly. When a valve is removed, the best way to put back is to open it slightly (turn counterclockwise to a low number), then reinstall the bonnet. Once it's back in, it should work like normal. If that doesn't work, perhaps you can get a plumber or a local handyman to check it. As to the upper ones being airlocked, it really sounds like there is a blockage in the supply line. I am assuming this is steam-heat radiator that is supplied by a boiler-type heating unit?
- 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:Full Bore ball vale and Reduce bore ball valve have diferent with each other ,I want to know about them.
- These okorder
- Q:i recently adjusted my valves on my 01 civic with a 1.7 sohc vtec motor and i did it to the specs under the hood and i didnt have them too tight or too loose on the feeler gauge and they are pretty loud are these motors just that noisy? has anyone else adjusted them to something different that works better?
- The dude above is physically powerful, yet incorrect on the fee. you may get an entire swifter equipment for about 1k, a reliable setup will fee a million.5k to 2k with injectors, gasoline pump, a turbine, and an intercooler. 01 are heavy and not super to do mods to, additionally d16 sucks inventory, so which you're able to additionally could desire to yet internals with expenses 900 for the aspects (pistons and rods). entire could be 2k to 3k for an extremely super setup for 250 to 300hp
- Q:Hey quick Q, I heard somewhere that you could degrease the the reed valve? I love cleaning up my CR250 as much as I can. I just want to know if this is done, and if you could, tell me where I'm supposed to clean.Thanks.
- Spray degreaser down the air intake-that should fix it.
