Q:i was thinkin i needed rings cause my car was smokin like hell and had a bad compression test on one cylinder. anyways i got the head off and my valves are caked with black **** all down one side and the others are completely white. i dont know if when the car turns off if they're supposed to seal but four of them were about a quarter inch off the head. before i tested everything i was smokin like hell and barely runnin and you could hear a knockin sound in the exhaust at the rear of the car. could the head be the problem or still sound like rings??: have the head checked for level milling it may be warped if it has ever overheated..

Q:where on the motor is the valves location: The idle air control valve can be found under the throttle body. In order to get to it: 1. Disconnect negative battery cable. 2. Remove air intake from throttle body. 3. Disconnect throttle body cable. 4. Disconnect sensor connectors from IAC valve, and throttle position sensor. 5. Remove 4 bolts from throttle body using 10mm socket wrench. 6. Take throttle body, turn bottom side up, remove 4 mounting screws from IAC Once you do that you have removed the IAC. Reverse the steps to put it back on starting at number 6 and working your way back to number one How do you replace an air idle control valve? Replacing an idle control valve can be a daunting task. For your specific application, we recommend to ask in our car forum for advice. Here we will describe the basic process for replacing your idle control valve. Please note that for different cars and trucks the process will not be the same. Steps to replace your idle control valve You will want to begin by first gaining access to the idle control valve. In order to do this you will need to remove the air filter assembly, along with the air mass sensor and the air mass meter boot. Once you remove this whole assembly, you should have easy access to the throttle body. Remove the four bolts that secure the throttle body to the intake manifold. Usually on the bottom of the throttle body, on fuel injected cars, there is a idle control valve. To remove the old valve, simply unscrew or unbolt it. Bolt on the new valve, and reinstall everything. Make sure you replace your throttle body gasket at this time.

Q:i went to the heart doc today to get the results from an echocardiogram and he told me i had two leakages in one of the valves of my heart. i dont know why, but i didnt even bother to ask him exactly what that meant because he told me it was nothing to worry about. can anyone tell me more about this?: Hum...it depends how bad your leakage is. If it causes too much blood to flow in the wrong direction it could cause an enlarged heart. What lead up to you having an echocardiogram? My son has has epstines malformation of the tricuspid valve and it caused leakage. It depends on the level of the leakage. It can be a big issue but obviously your leakages are small and nothing to be concerned with? I would def. call him and get some clarification....

Q:Okay I know lots of people wonder what is better presta or schrader...well I realy don't. My bike was made for presta and thats what I have a question about. So I just got my bike back after is being stored away for a few years, so yeah it was neglected. Question is now that I am doing a tuneup on it I found out the valve came out of the tube. I don't know if that is normal and if I am able to put it back in. It looks like there made for the valve not to come out but I just want to make sure before I go out and buy a new tube. Hope you can help. Thanks. -Sarge: First off, there is no question that presta valves are better! The larger a hole drilled through a rim, the lower its strength. Thus, all other things being equal, a rim drilled for a presta valve will be stronger than a rim drilled for a schrader valve. Tubes with presta valves are slightly easier to pump with a mini-pump than a schrader valve. Finally, they are a bit lighter than a Schrader valve. Secondly, you need to buy a new tube. There is utterly no hope for a repair if the valve comes out. Hope this helps.

Q:Leak in Heart Valve ?i was told by my doctor to to do a ultra sound on my heart a few weeks ago, wehn i finished the ultra sound the lady that did the scan asked if i had any type of heart disease in my family, and i responded that i dont, she said that i have a leak in my heart valve, but that was all, i dont have an appointment with my doctor til two weeks from now, i THINK i feel shortness of breath, but i feel like this may all be because im scared ...... main thing is has anyone had this or know anything about this is it dangerous, deadly ? should i be scared ?: It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.

Q:Im trying to make an apparatus that would allow you to breathe in from one tube and exhale through another is their a valve that does this. I originally thought that a one way valve might work however I cannot find one that works with suction.: Position two backflow preventers in oposite directions on your supply and exhaust line. connect them to a Tee fitting. the third end of the tee is where you will breathe

Q:I was wondering if the pressure relief valve can be vented right under the house or does it have to be ran to the outside of the house. Also is there another method such as a catch pan that I can employ? I live in Washington.: I would be curious to see what plumbing professionals have to say about this. From what I could find, the codes for water heater relief valves just say that the valve must have a drain pipe that discharges the hot water and steam down low, instead of up near the top where it can spray in your face. They also say that the discharge should be outside of the building, but that this is not always feasible and you can install a drip pan below the water heater for this purpose. In this case, I would think that running the discharge line to underneath the house should be okay. But, I'm not a plumber. For what it's worth, my water heater is in a closet that's accessed from outside and the discharge line from my pressure relief valve just discharges to the bottom of the closet (this was installed by a licensed plumber and signed off by the city on a remodel 2 years ago). Apparently, it's okay to just let the discharged water flow out from underneath the water heater closet door to the outside. So, I don't see why it would be against code to run the discharge line to a crawl space under the house. The point of the codes is to prevent your water heater from exploding and destroying your house (or killing or injuring you).

Q:My valve cover gasket has less them 2k miles on it and i noticed in some areas there is a lil oil shine around it so i was thinkin maybe i have to retighten the valve cover a lil bit more?: I would tighten them a little. Hope you cleaned the valve cover and head good before you installed the gaskets.

Q:I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work): Get a straw and put it in a glass of water. Suck the water up the straw and what happens? Get that same straw and punch 6 holes in the center around the straw. Suck on the straw and what happens? That is the purpose of the bypass. Now the speculation behind the bypass is the intake system has to be fully submerged for it to work efficiently. Get your aftermarket straw and hold it sideways nearly touching the top of the water and suck real hard. You will notice water gets to your mouth, and so your engine. Nothing more than a pressure differential. Bypass valves are very expensive parts for people that don't understand principles of pressure and vacuum. Don't waste your money on it, but stay out of deep puddles.

Q:I want to know if a person with multiple leaking heart valves left untreated, is in any more danger than someone with a single leaking heart valve.: Depends on how severe the leak is. If multiple valves have only trace leakage then no its not more worrisome then someone with Mild, moderate or severe leakage in one valve because trace leakage is a very small amount and almost everyone one has some. Now if someone had multiple valves that were moderate or severe yes that is more worrisome then some one with only 1 mild, moderate or severe valve leakage. If multiple valves have only mild leakage i think 1 valve with severe leakage is still more severe. I am NOT a doctor so this is just things that i am fairly sure about but not 100% sure of. Go to a cardiologist and ask him/her if you want a reliable accurate answer.
