Q:A question about tricuspid valve disease..?
Any sort of valve surgical technique includes exposing the aorta of the midsection, hence it rather is one among those open heart surgical technique. over the years, this has replace right into a incredibly simple technique for heart medical doctors and it has a fulfillment fee of in simple terms approximately 80-ninety 5%. there is an threat which you may choose yet another surgical technique afterwards, yet that purely happens in approximately 5-10% of sufferers that get the surgical technique. The survival fee for this operation is extremely extreme and purely 5-10% of sufferers adventure any undesirable outcomes throughout the surgical technique. This consists of an infection, stroke, allergic reaction, or bleeding. i'm going to keep you in my prayers Alex. maximum suitable of success to you!
Q:stop intake valve leakage in auto?
IF the valves are correctly adjusted, then the only solution is a valve job. Certain vehicle engines are more prone to burning valves than others.
Q:Is it safe to ride a motorcycle with tapping valves?
Noisy valves are better than quiet ones. Quiet means the valves are not fully closing, and exhaust gases will squeeze out the intake and exhaust ports causing burning of the valve seats. Shouldn't hurt too much to ride it until it's convenient for you. Keep an ear out, if it starts to get louder or somehow changes suddenly, you'll probably want to take it in right away.
Q:shuttle valve location?
The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
Q:Controlling a butterfly valve?
You can purchase operators for some butterfly valves for either on/off operations or to modulate but the flow characteristics of a butterfly valve makes is a very poor modulating control valve,
Q:Is a EGR valve necessary?
It used to be a cheap fix. I haven't worked on the newer vehicles, but it used to be an F-shaped plug, with vacuum hoses, that you could replace in a few minutes. Price was under $20. The biggest problem, then, was decoding the codes! I just looked it up and it seems to be pretty simple, and similar to what I worked on. A small diaphragm valve that runs about $50. Ford would probably charge you $300 for the part and another $100 or so to put it on. The EGR valve helps with exhaust and, to some degree, gas mileage. In other words, if you live in a state with strict rules about emissions, you may fail the test. In proper condition, you may notice a little better fuel mileage. Of course, when I drove a sports car, I noticed that a good waxing helped my mileage. LOL I doubt that the Flomaster would cause a problem. This is a sensor issue that is, or should be, directly related to the EGR valve itself. Of course, I haven't worked on vehicles for years, so... Google this and see what you think. Location should give you some pictures to show where it should be on your Mustang and then you can see if you think you can do it. Then, check the prices. If your state is a pain, fixing it is probably cheaper than failing the emissions test. Besides, the more work you can do yourself, the cheaper it is. The only real difference between you and the guys who work in the dealership is a degree (piece of paper) and a fancy machine. You can do the same things they do.
Q:How do I fix a knocking valve?
valves dont knock they tap and generally all you have to do is adjust the valve lash, but you may need new valve springs if those heads have alot of miles or were abused.
Q:Toilet shutoff (stop) valve problem?
Definitely the tank float valve needs adjusting. Take the tank cover off and look at the water level, should be up pretty high and just below the venting tube. If it's not you need to adjust the valve. One quick and easy way is to bend the rod that is located between the float and the valve. Bend rod down so that the float sits lower in the tank. This should increase the amount of water in the tank. Some valves have a screw to adjust the water level. If this is the case you'll have to screw in one direction to see what the effect is (more or less water in the tank) then make the adjustment you need in the appropriate direction (screw in or out). Not a big deal, you can do it.
Q:Intercoolers and Blow off valves, turbos?
A blow off or pop off valve controls the boost or pressure the turbo or supercharger is pushing into the engine.A turbo makes the boost.The blow off valve controls it so you wont run too much boost or pressure into your engine and leave pieces of it all over the street.The blow off valve can be adjusted to control the boost,6- 8 lbs.should be sufficient for a street application.The blow off valve simply allows the excess pressure built up in the turbo to be vented or blown off so it wont be forced into the engine.The boost on a supercharged or blower application is controlled by swapping the blower pulley to either underdrive the blower or overdrive the blower,depending on which way you want to go.
Q:brake proportioning valve?
Yes The valve causes your rear brakes too apply before the front brakes .Safety reasons,(If your fronts apply first chances are the rear of the vehicle could come around on you) It utilizes spring pressure and offset valving. There is a rubber button that you must depress to bleed the rear brakes It's an override.
