Q:I have a honda civic and i took it to get an oil change and they told me that i had an oil leak because my valve cover needed replacing. I did not let them do the work. I called my personal mechanic and he's out of commission for a little while, so he referred me to a friend of his. He said he cleaned all of the built up oil and replaced the valve cover. I noticed yesterday that my car looks like it is leaking oil really bad. I'm wondering, could this be from him washing the old oil that was leaking? My belts seem to be squeaking, like they do when it rains. Any ideas? could this just be excess water that he cleaned it out with?
To determine If the valve cover-gasket is leaking again, take the car to a wand-type car wash. Shut the motor off, open the hood and thoroughly wash the engine and compartment down with hot water and soap. Concentrate on the valve cover itself and the mating surface between the valve cover and cylinder head. Rinse with hot water spray. This is the only way to clean-up the previous mess so everything will be dry and clean. Use a flash-light if you have one to inspect all the way around the lip of the valve cover to look for any bright, shiny oil that could be leaking again after a short drive. Having been cleaning engine compartments for 45 years at car washes, don't worry about electrical connections, cracking or breaking anything. There are quite a few tricks to make valve covers seal properly. To start with the cylinder head has to be clean and dry, the valve cover had to be clean, *flat and dry and use only premium Felpro, silicone impregnated valve cover gaskets.
Q:When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.
On most engines the PCV Valve is located on the valve cover. You would remove the PCV valve from the valve cover but leave it connected to the vacuum hose. Otherwise you would have a severe vacuum leak and the engine would race wildly. With the PCV valve still in place the engine would idle somewhat normally. Pour the Sea Foam directly into the PCV valve. The Sea Foam would be sucked into the PCV valve and into the intake manifold. Be careful not to over do it on the first application. If this has not been done for a few years enough gunk can be washed out of the intake manifold that it can foul the catalytic converter. I would apply the Sea Foam. Have a friend shut off the engine while the Sea Foam is added. Allow the Sea Foam to soak for several minutes and do its job. Reconnect the PCV valve. Start the engine and drive the vehicle for several miles. This will allow the catalytic converter to burn off the gunk that and Sea Foam that has passed through the engine. Repeat as necessary.
Q:If someone is not born with heart valve disease... can a teenager or a 12 year old develop heart valve disease?
If a teenager is not born with vavular disease, he/she can develop valve defect in one of the following ways: 1) Rhuematic Heart Disease, the commonest cause: Rheumatic heart disease is a complication of rheumatic fever and usually occurs after attacks of rheumatic fever. Rheumatic fever causes rheumatic heart disease. Rheumatic fever results from an untreated strep throat. Rheumatic fever can damage the heart valves. Some of the most common symptoms of rheumatic heart disease are: breathlessness, fatigue, palpitations, chest pain, and fainting attacks. Treatment of rheumatic heart disease may include medication and surgery. Medication will aim to avoid overexertion. Surgery may be needed to replace the damaged valve(s). 2) Infecions, viral/bacterial, of heart can cause valve problems as complication. Other causes: # Systemic lupus erythmatosis (SLE). SLE and other immune diseases can affect the aortic and mitral valves. # Carcinoid syndrome. Tumors in the digestive tract that spread to the liver or lymph nodes can affect the tricuspid and pulmonary valves. # Metabolic disorders. Relatively uncommon diseases, such as Fabry disease and hyperlipidemia, can affect the heart valves. # Diet medicines. The use of fenfluramine and phentermine (fen-phen) has sometimes been linked to heart valve problems. These problems typically stabilize or improve after the medicine is stopped. # Radiation therapy. Radiation therapy to the chest area can cause heart valve disease. This therapy is used to treat cancer. Heart valve disease due to radiation therapy may not cause symptoms for as many as 20 years after the therapy ends.
Q:i ha valveve a knock on the driver side .and i have to remove the intake manafold to get to the valve
Really? I find that innane. rocker covers usually come off pretty easy, and are well above the manifold-unless its a sidevalve???
Q:my pcv valve tube is broken in half I replaced it with a rubber hose does it have to be whole
no, i'm prety sure the pcv valve is to help the engine run smoothly. or something that has to do with the engine, i really dont think that is related to the tramsmission
Q:Water has been seeping out of the sprinklers closest to the anti-siphon valve. Water seeps out of the sprinkler even when the anti-siphon valve is manually closed and not connected electronically. I opened up the anti-siphon valve to inspect the diaphragm, but there is no debris nor it was damaged. To be sure, I switched the diaphragm chamber of the two anti-siphon valves (a suspected leaky one and another good working one), but leak persists from the same sprinklers. I think the leak is from the (float?) rubber seal at the bottom of the stem closing the inlet valve. My anti-siphon is a Hardie (or Irritrol) model 311A series.1) Is my troubleshooting and logic correct? What other components could have contributed to the leak described? 2) At what scenario will water be flowing out of the anti-siphon cap?3) How can I determine if my anti-siphon valve has a vacuum breaker? What is a vacuum breaker good for?4)Which brand makes the most reliable anti-siphon valve?

Q:I have this air canister i want to attach to a homemade Airsoft gun. (please no comments or answers on that).The air canister has an opening on both ends. I thought for simplicity, put a filler valve on one end and a connection to the gun on the other.Exactly what kind of one way filer valve will i need, most of the ones i look at look like propane tank connections and those are for filling and dispensing into the system.
go to a tire store, get a tire valve, then you can fill it with any kind of air pump.
Q:2004 R6. Runs really well... never had a problem. Has 24K miles on it. Yamaha calls for them to get readjusted at the 26,600 mile mark. So I have a few thousand more and then I'm gunna have them adjusted.I can already hear them tick especially at idle because when riding, my exhaust is so loud and all you can hear is that and the wind. Anyway, this time will come up before I know it.Just curious... what happens if the valves remain loose? Will it affect performance? How do you they become loose and is it ok to ride a bike with them like that... atleast until the specific mileage when they are supposed to be adjustd?
Loose valves don't actually cause any major problems or damage. The only loss is power and economy. A tight valve is what you don't want. A loose valve opens later and closes earlier than it should, so less air/fuel is getting into the cylinder. A tight valve can burn up because it may never actually 'close'. You won't hurt anything by continuing to ride the bike, but there is absolutely no reason why you should continue to ride the bike without getting the valves adjusted.
Q:how long do people usually live after mitral valve repair?
depends on luck and how you deal with life?
Q:i have a 8v fiat punto...is it much work to add 2 valves to make it a 16v?
Erm.........8 plus 2 is 10, not 16. And no, it isn't possible.
