Q:Is this possible? The valve is way too big to fit the rim. Is there a special inner tube for this rim? Thanks in advance.: There are two kinds of valves used on bicycles. The large one, the Schrader valve, is the same as the valve used on cars. The thinner one is the Presta valve. The only possible way to get into the situation you describe is to have a Schrader valve tube and a Presta valve rim. Take the tube back to where you bought it and exchange it for a Presta valve tube. Presta valves are easy to operate. To inflate them, remove the plastic cap if one is there. Fully loosen the fitting at the top of the valve. It will not come off. Inflate the tire to recommended pressure with a Presta valve pump, a pump that automatically does both valve types, or a threaded adapter that will let you use a Schrader valve pump (remove the adapter when done). Then, screw down the fitting that you loosened to start. You really don't need the plastic cap. Their purpose is the keep the valve from puncturing the tube when the whole thing is folded up. Once you've installed the tube in the tire you don't need the cap any more. HTH EDIT: (sorry for shouting) DO NOT DRILL OUT THE RIM! That has the potential for serious safety problems.

Q:I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.: Pvc Shut Off Valve

Q:The diablo tunner says you can cut off your EGR valve, only if your going to take it off. What effect will this have on the car?: The EGR valve or Exhaust gas Recirculation valve is located on the exhaust equipment. those often get hung up with rust and different exhaust deposits. The motor vehicle may be under production facility guarantee being basically 3 years old. i might verify with a broker to work out if the motor vehicle and/or section remains under guarantee. A defective EGR valve will reason the workstation to make the incorrect settings to the gas and air blend inflicting the engine to run too rich or too lean. Its no longer too unfavourable interior the quick term, yet your gas mielage will go through, and you will be able to fail a state inspection so get it repaired before then.

Q:My mum (73, non-smoker, not overweight) has been diagnosed with 2nd degree aortic valve stenosis 5 years ago. Now deteriorating. Her cardiologist sees her every 6 months and strongly recommends surgery. She is too scared as dad died during a coronary bypass op. Any tips how to gently make her feel better about the op? She heard on the radio that some valve replacements can be done via catheter, not necessitating open heart surgery and heart-lung-bypass. Is that true for aortic valves and is it likely to become mainstream soon? She lives in Germany, so I guess good centres would be Munich, Wuerzburg and Heidelberg. Any views very appreciated!: Without surgery, a person with aortic stenosis who has angina or signs of heart failure may do poorly. Possible Complications * Arrhythmias * Endocarditis * Left-sided heart failure * Left ventricular hypertrophy (enlargement) caused by the extra work of pushing blood through the narrowed valve Aortic stenosis can be cured with surgery. After surgery there is a risk for irregular heart rhythms, which can cause sudden death, and blood clots, which can cause a stroke. There is also a risk that the new valve will stop working and need to be replaced. According to a prospective, single-center, nonrandomized study of 25 patients, percutaneous implantation of an aortic valve prosthesis in high risk patients with aortic stenosis results in marked hemodynamic and clinical improvement when successfully completed. Medium- and long-term results are unknown. When selecting the optimal therapy for individual patients, the percutaneous approach must be carefully weighed against the excellent results achieved with conventional surgery. Please note that I am not a medical professional.

Q:what exactly causes a valve to stretch?: Gets warped by the heat and friction over time

Q:i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank: srry but if u do that it works very poorly so i would buy that scuba tank

Q:my EGR valve has gone on my Vauxhall Vectra 2.0 DI LS, 1998, 5 DOOR HATCHBACK, so i am getting a new one next week, what i want to know is, is it an easy job to replace them if so how do i do it? or is it better just to let a garage do the job?: Egr Valve Vectra

Q:Do I need breathers too??? Cause I believe that there is a hose that runs from the valve cover to the carb then a breather as well??????? and If i do end up putting a hose in will it suck the oil out or just the gases casue the mopar vavle covers dont have anything blocking the oil and rocker arms from splashing on the PCV Vavle on the inside????? FEEDBACK IS APPRECIATED: Mopar Performance Valve Covers

Q:I recently adjusted the valves and put new valve covers on my bug and now I have a leak around the fron corner of one of my valve covers. What happened? What can I do?: For clip on valve covers it best to add some tension to the wire bails. You can do this by slightly bending the centers inwards. Also a light coat of Permatex ultra gray on both sides of the valve cover gasket works great. When you replace the valve cover gasket, the services it rides on on must be very clean. So pop off your covers and perform the steps above and you should be fine. Here is a link to a video we made on valve covers.

Q:So I bought my car about 4 months ago (1999 mustang) and the second day the check engine light came on and was the code for the EGR valve. I just reset the ECU and it went off and stayed off until now. Same code for the EGR, but this time after resetting ECU the light continues to come on. Is the EGR valve important enough to have fixed? and I have aftermarket Flomaster exhaust if that would have anything to do with the code being thrown: It's there for a reason.
