Q:Question about Trumpet Valve Stem How to Replace it?
I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.
Q:Two PVC valves?
No No No, The PVC valve removes a measured amount of crankcase blow by, oil vapor and water to be re-burned in the combustion chambers for emissions standards. The breather in the valve cover is needed to let atmospheric pressure in the crankcase to replace the air the PVC valve and hose has already been removed. I think you've been reading up on dry sump systems. Race engines make more power with a crankcase under vacuum while running.
Q:aortic valve stenosis severe amemia hemoglobin 9.1 ?
I developed severe anemia when I was diagnosed with aortic stenosis. The Dr told me it was due to the damage the valve was causing my blood cells. He told me it also caused problems with my blood not clotting right and it would stop after my surgery. He was right and I haven't had problems since.
Q:Pitted Exhaust valve on generator, can I just replace valve?
There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.
Q:Biology help!! What is Atrial valves?
there isn't a sinoatrial valve in the human heart. There are 2 AV (atrioventricular) valves, and 2 semilunar valves, which are the aortic valve, and pulmonary valve. The AV valve seperate the atrium (on top) and ventricle (on bottom). Blood flows down from the atrium, to the ventricle, and then the AV valve closes to keep blood from going back into the atrium. While the valve is closed, the ventricle contracts, which send blood up through, the aorta ( left side) or the pulmonary trunk(right side). The semilunar valves seperate the ventricles from the aorta and the pulmonary trunk.
Q:How essential is an EGR Valve to the operation of a car?
An EGR error code doesn't necessarily mean the EGR valve itself is bad. Many times they just need the carbon cleaned out of them as well as the intake manifold passages they connect to. The EGR valve is normally closed at idle, and opens to cool the engine with the exhaust gases and reduce NoX emissions. The computer is calibrated to operate the engine properly only with the EGR opening as it should at highway speeds.
Q:Sprinkler valve leak?
You are turning on electric valves, manually, with the bleeder valve (little black twisty thing). It is normal for this to happen. This valve can turn on and off a zone, but it also releases air from within the lines causing water to spit out with it. After the air is out, you can twist it down enough to stop the leak and still have that zone remain on.
Q:can EGR valve make engine run hot, melt pistons?
Interesting that the 100 and 106 CI Victory V twin has no problem overheating with an oil cooled engine and the STOCK 92 CI Victory produces more HP that the guy with the 103 CI Screaming Eagle HD. Add a oil cooler to the HD and it will not overheat but still gets blown away by the Vic. That 103 and 110 CI upgrade is the biggest ripoff they have going and creates more of an overheating problem than the stock engine. They overheat because the engine is an ancient design that has been stretched to its limits in an attemp to keep up with bikes like the Victory. By the way the Robb Report just named the 2009 Vision best touring motorcycle and it does not overheat either.
Q:Tell me all you know about Blow-off valves?
It is often used as a safety devise in many industrial fields, first introduced on the early steam engines of the 19th century to prevent the boilers from blowing up due to excessive steam pressure. They still did often blow up as the early valves were quite primitive and often stuck closed,
Q:Explanation on enlarged heart valve?
•UPDATE• We went to the US today and the heart was 100% HEALTHY!! There was nothing wrong with any anatomy of baby girl. The doctors there said they are completely confused as to why my Doctor would tell me the baby might need heart surgery when she wasn't even 100% on the issue and even if it was due to positioning like she 'claimed' at first, then a Level 2 US wouldn't be necessary. I'm just so grateful and thank God that my baby is ����!
