Q:ducati valve adjustments?
believe it or not a desmodromic valve adjustment takes like 8 hours.So its kinda costly to do that job.
Q:What is a foot and check valve what's the difference between the two?
A foot valve is a check valve with a screen to stop debris. It depends on whether you're pumping water with alot of sediment.
Q:what are symptoms of bent valves?
Misfiring at low engine speeds. Usually, this would happen if you have had a leaking exhaust manifold gasket for a while which would actually cause the valve to get burned from high temperature. An actual BENT VALVE is easily spotted if you remove the valve cover to the suspect area and relieve the stress on the valve stem when the engine is at TDC on this cylinder. If there is too much play , or lash, between the cam and the valve stem, then the valve is not closing and is therefore, BENT!!
Q:What are the reasons a Schrader valve might need replaced?
After replacing all these parts it should have corrected any restriction. If it was vacuumed out there should be negative pressure in the system and accept a charge through the low side port. If you did not see the actual work done im wondering if the parts were indeed changed?
Q:Mitral valve prolapse have impression on lifetime?
Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
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:How does a thermal bypass valve work?
Water flowing into the valve is directed to two outlets. One outlet directs water back into the engine to recirculate and the other outlet directs water to a radiator where its cooled and the returned back to the engine. The amount of flow diverted to these outlets depends upon the position of the valve disk. In a car engine the water is constantly recirculating through the ports of the engine and the thermostat is located in one of these passage ways. The thermostat and its valve creates a third port or second outlet that allows water to flow to a radiator. When the valve is closed the water bypasses the radiator and recirculates hrough the engine. How much flow is diverted to the radiator is done by a temperature sensitive component that causes mechanical movement of the valve position based on the water temoerature flowing through the valve. the hotter the water the more flow that is diverted to the radiator to cool. The colder the water less flow is sent to the radiator and more flow is recirculated back to the engine bypassing the radiator. The mechnical sense element of what is commonly called a thermostat is called a pill. It consists of a sealed unit which for lack of a better description acts like a piston inside a cylinder and the cylinder is filled with wax. This piston is free to move back and forth but is limited in its movement because the wax is incompressible and a spring is pushing the piston back agains the wax. Now as the temperature warms up the wax melts and the liquid wax expands as it heats up. As the wax expands the piston is moved agains the spring and the shaft attached to the piston is used to move a disk away from the seat of the valve and allows more water to flow to the radiator.
Q:Valve cover painting in 1990 BMW 525i?
If you want just flat black paint, grill paint works great and gives it that crinkled effect. You can get it at most hardware stores.
Q:Valve seat removal?
takes a stand up mill. to cut the seat and heat the head and install the new seat...
Q:Leaking car tyre valve?
you can take the old valve out and put a new 1 in. auto zone sells new valves.
