Q:Is it ok to reuse valves?
hey why dont you go down to your local machine shop and ask a few questions,try and angle a cleanup job to trade for labor and experience.in other words,why dont you go ask your dadlove that commercial
Q:How to adjust valves?
if okorder.com and download the free bee manual for your bike.
Q:ford escort pcv valve?
VERY easily. The rubber hose that is routed to the top of the throttle body on one end, is connected to the PCV valve on the other end, where the exhaust manifold is situated, by the radiator cooling fan.
Q:what is an oil pressure relief valve?
The oil pressure relief valve is a type of valve used to control the oil pressure in the car engine. Oil pressure can build up by a motor malfunction, low volume of oil, instrument or equipment failure, or fire. Basically, oil pressure is relieved by allowing the pressurized oil to flow out from an auxiliary passage system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the path of least resistance as the valve is forced open and a portion of the fluid is diverted through the auxiliary route. In the 2003 Ford Focus, 3.8 engine, the oil pressure valve is located on the back of the timing cover above where the oil pump bolts up... don't install it backwards you will have the same problem... while everything is dismantled, I suggest you change your oil pump, also; and you will get a new pressure relief valve with it. I hope this helps Papaw
Q:Can i smoke pot with and artificial valve?
I don't smoke anything. So pot was not an option for me. With that said I really do not have a problem with those that choose to do pot. I feel the same way about it as people that smoke. Please don't do it in my house, or in a confined area where I can't get away from it. I really do not want it around my kids. I think pot is safer then alcohol. I have known people that smoked pot. The majority of them did it to relax which meant they were hanging out at home. I feel that it should be legalized as that would kill a HUGE crime industry. Not much point in smuggling it over the borders or having secret deals with individuals when that person can run down to the local convenient store and pick it up. It could also be extra income for the governments as they could profit off it. I don't think it should be done while children are being watched. Like any substance, regardless of how mild it may be, it can impair your judgement. =)
Q:Mitral Valve Prolapse..Help please?
good blood does not mix with bad blood. The values have nothing to do with that as the two sides of the heart are separate. With Mitral valve incompetence or prolapse, the valve does not close like it is suppose to. That allows back flow of blood. If bad enough, the treatment is a valve replacement. With Mitral valve stenosis, the valve does not open like it is suppose to. That prevents flow through the valve. The treatment is a valve replacement or sometimes a simple cut in the valve to relieve the stenosis can be done. Either way, if bad enough, surgery is needed, not pills.
Q:Using a valve spring compressor?
save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar
Q:what happen when solenoid valve is activated?
If the pressure in any one zone is different than the other zones it could be one of two reasons; either the pressure is high (usually due to one or more sprinkler heads not poping up), or its low (usually due to a leak in the pipes). Something that could cause low pressure in all the zones are an obstruction in the water line above the valves (unlikely), or a hole in the line above the valve (the water would be filling the valve box and causing damage to the lawn wherever it is located), or leaks in all the lines (again would be easy to identify from the excess water in the ground at the source of the leak). Lastly the valve itself could potentially be faulty. The solenoid inside the valve holds the valve open when electricity is applied across it. If the wires to it are damaged; if the solenoid is bad; or if the valve has any rust or dirt inside that could cause a lower than normal amount of water flow.
Q:My son has a Bycuspid Aortic valve....does anyone else...?
A bicuspid aortic valve is not necessarily a problem - a normal aortic valve has three cusps, and your son only has two. Having only two cusps is not a big deal. The mitral valve in the heart naturally has only two cusps, so three cusps are not needed for a heart valve to function. The advantage of three valves is a slight increase in efficiency, but the difference between a normal valve and properly working bicuspid valve would only matter to a professional athlete. If the aortic valve closes almost completely, there is nothing to worry about. Since he has a heart murmur, its possible that it is caused by having only two cusps, but people with three cusps commonly have murmurs. There is no reason to get the valve replaced simply because of only two cusps. What matters is the level of aortic valve regurgitation. If regurgitation is not significant, your son has a normally functioning heart. Even if he had a moderate or high amount of regurgitation, it still might not have enough effect to warrant surgery. There are tests to measure regurgitation.
Q:EGR valve?
You can only take the EGR valve off the car IF you cover the intake and exhaust ports properly. The effects will be: Excessive NOx production. Increased tendency for detonation. A much shorter engine life expectancy. I just don't understand why play with this unless you run unlimited fuel (and don't mind rebuilding your engine after every race)? EGR valves are designed not to hamper with performance, only to reduce emissions of NOx and protect (in a way) your engine.
