Q:Volvo 850 blue smoke exhaust. Most likley Valve seals? or valve guides..or something with the valves.?
Do a compression test, that'll tell you exactly whats wrong. Or have a mechanic do one.
Q:Gas safety valve does not work for thick slurries?
I suggest that you rethink that application. Even if the valve does function it might not pass enough slurry quickly enough to relieve the pressure overload.
Q:I need help with my trumpet/cornet valves?
Every trumpet I've used has numbers on the valves. These should be facing you when inserting the valves, valve 1 being closest to you, and valve 3 being closest to the bell.
Q:Should I have this shutoff valve replaced?
A new valve is around $6. If you were able to do the work you did you certainly are capable of replacing the valve by yourself. That plumber is yanking your chain.
Q:Wall Heater question? (Gas Valve)?
I assume you mean the soleniod controlled valve. I also assume the pilot is lit, or the electronic ignitor glows (which ever it has) but the main burner doesn't lite. Use a test light (I prefer neon) or a meter to check the voltage to the soleniod. If the voltage never goes to 120, then there is something wrong upstream. If it does and the burner doesn't light, most likely the soleniod is bad. Also, you should hear it click when it opens and you should hear the gas.
Q:Heart Valves?
A good friend of mine ignored his bad cold symptoms and was diagnosed with pneumonia when it already affected his heart valves.
Q:What is a purge valve in cars?
the purge valve as it was refered to is in ur fuel pump on ur car and yes this happens offen when ur fuel pump is in ur fuel tank u should never run below about hafe a tank on a hot day because your fuel is what keeps ur pump from heating up and when u run low on fuel ur purge valve can over heat and warp hope this helps good luck
Q:mitral valve prolapse syndrome?
Mitral valve prolapse is known to lead to chest pain, but the exact cause for the chest pain is not understood. The chest pain related to mitral valve prolapse is described as atypical, because it does not have the typical characteristics of other heart related pain. It is possible that your chest pain may or may not be related to your mitral valve prolapse. Chest pain that occurs or worsens with breathing is suggestive of a problem with the lining around the lungs (pleurisy.) A musculoskeletal cause like a pulled muscle is also possible. Anxiety would also be a possible cause. None of these conditions are serious. Chest pain resulting from MVP is not known to lead to any negative health consequences. Discuss it with your Cardiologist if you remain concerned.
Q:Installed a iac valve?

Q:Leak in Heart Valve ?
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.
