- Q: From searching around I feel that I need to replace this on my vehicle. Is the Suction Control Valve different from the Idle Control Valve? Sometimes at a stop light the engine will stall. A couple times it has happened while driving when coasting to a turn or stop.
- hold the computer near the Pathfinder it will suck data directly off the internet (NO WAY) what you need is a complete diagnosis by a experenced Technician or a Nissan Technician. Idle control is on the bottom of the throttle chamber or on the intake manifold. Stalling and Dieing may be caused by a Distributor or air flow meter fuel pump or clogged up fuel filter. Suction control valve in not a part on your year pathfinder good lick
- Q: what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
- Sclerosis means hardening. Aortic sclerosis, a degenerative aortic valve disease with thickening of aortic valve structures by fibrosis and calcification initially without causing significant obstruction, is the most common cause of AS in elderly patients. Over years, aortic sclerosis progresses to stenosis in as many as 15% of patients. Aortic sclerosis resembles atherosclerosis, with deposition of lipoproteins, active inflammation, and calcification of the valves; risk factors are similar. Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left lower chamber of the heart to the aorta. The aorta is the main artery leaving the heart. Aortic insufficiency is a heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly. This leads to backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (the left lower chamber of the heart). Causes of increased afterload that can cause LVH include aortic stenosis, aortic insufficiency, and hypertension. Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies, which can lead into heart failure.
- Q: I am being sent for a level 2 Ultrasound Thursday because my previous US showed one of the babies valves was enlarged. She said all 4 chambers were there but she was very vague on what this means. Care to shed some light?
- I don't know what this means in a fetus at 20 weeks since a lot of changes still lie ahead, but you can glean some info from the nature of this type of defect in adults. If the abnormality doesn't change and if no other abnormalities arise, the flaps of the affected valve will poke into one of the heart chambers. This situation is called valve prolapse. Look up mitral valve prolapse as an example. Typically a valve prolapse is not a serious defect, but if the prolapse is severe it might require treatment at some point in life or maybe even multiple treatments. What the heart will look like at birth is probably the bigger question. Some abnormalities signal a genetic defect that might cause other problems as well. Some defects cause a chain of problems in later steps of development. Your doc should have a good idea if any of these concerns exist. Maybe genetic testing will be suggested, but many defects occur with no explanation and they do not cause other complications. I would guess that after the chambers are developed, a dilated valve would be unlikely to cause any significant complications in later heart development, but this is just a guess.
- Q: I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project
- take the heads to your local automotive machine shop and have them do the valve job they will fix whats wrong with your heads.and for parts you will need a head set gasket kit from auto zone or summit racing,and new spark plugs wire's oil, antifreeze,belts water pump since you have the room to get to it now,
- Q: I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?
- Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.
- Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
- Getting a vlave job done isnt going to hurt your car at all, nor your motor. Make sure you have a reputable machine shop do this (most garages dont have the tools for it). If a 3 angle valve job is done correctly and new valve stem seals, retainers, and spring are all carefully installed to manufacturer spec then there should be no problem at all. Many shops will do a sloppy job grinding the valve face (which is a hard thing to get the knack for) and will install to valves without another thought. When new valves or old valves with resurfaced faces are installed the spring rate of the valve springs needs to be checked to ensure are srpings are the same strength. Also once installed, the height of each installed valve/spring needs to be checked to make sure its in the specified allowance. If valve seats and surfaces are all done correctly along with a profesional installation I wouldn't worry!
- Q: So I bought my car about 4 months ago (1999 mustang) and the second day the check engine light came on and was the code for the EGR valve. I just reset the ECU and it went off and stayed off until now. Same code for the EGR, but this time after resetting ECU the light continues to come on. Is the EGR valve important enough to have fixed? and I have aftermarket Flomaster exhaust if that would have anything to do with the code being thrown
- It's there for a reason.
- Q: Specifically, what is the mechanism which leads to pressure drops in expansion valves?
- THERMOSTATIC EXPANSION VALVE A temperature-regulated valve that controls the amount of restriction to refrigerant flow between the receiver/drier and evaporator. Like the Fixed Orifice Tube, the Expansion Valve is the boundary between the High and Low sides of the refrigerant system. Unlike the Fixed Orifice, the Expansion Valve can regulate the flow of liquid refrigerant to the evaporator to either increase or decrease evaporator cooling based on the temperature of the refrigerant tube at the evaporator outlet. In vapour compression ref. cycle,The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. The auto-refrigeration effect of the adiabatic flash evaporation lowers the temperature of the liquid and vapor refrigerant mixture to where it is colder than the temperature of the enclosed space to be refrigerated.
- Q: 1998 camaro3.8L v6sometimes when i start the car, it makes this loud ticking noise that goes with the RPMIm pretty sure its the valve, anyone know how to fix it, and how much it might cost?
- HI what you are hearing is not a valve but a lifter... MAYBE... Here's a couple of things that well make it tick. 1) an exhaust manifold gasket leak well sound like a ticking lifter. ( if the noise goes away after the car warms up it might be this gasket.) 2) a bent push rod well make a lifter tick ( as the tolerances would be off) 3) a bad lifter well make a ticking sound. If it is indeed a lifter then best leave it to a pro.. As the intake would have to come off to replace ALL the lifters (you can't buy just one). If its a push rod just the valve covers well have to come off.. to isolate the sound you can use a long piece of hose 3 ft. or so. hold one end to your ear and move the other around the motor compartment and see if you can tell if the sound is coming from inside the motor (lifter), inside the valve cover (push rod) or outside the motor exhaust gasket. good luck tim
- Q: I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.
- My aortic valve (amongst other things) were replaced/repaired during an emergency aortic dissection surgery. My surgeon chose the mechanical valve for me. I am hopeful that it will last a long time (I am only 26) so that I can minimize the need to undergo replacement surgeries. Yearly, I see my cardiologist -- they do a CT scan and check to ensure the valve is functioning properly. The valve does have a loud click to it -- it's something that you notice a lot when you first get it, but after a little while you hardly notice it.
