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 have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!
They open different amounts at different RPM ranges. Opening them all the way would cause the engine to have zero power until the engine is reving wide open.
Q:My washing machine had hot and cold water, but was leaking. I changed the inlet valve which stopped the leak, but now I have no hot water. When I put the setting on warm, the cold water runs for a bit. Then stops and no hot water comes. Any help?
I suspect the leaking valve that was replaced was your washer's solenoid valve. Did you remember to turn the hot water supply valve on after you finished? That is the valve, next to the cold water supply valve, on/at the wall behind the washer. There are rubber hoses coming from those valves to the solenoid valves on your washer. If you forgot to turn it back on after replacing the leaking valve you'll get no water. If you turn off both the hot and cold supply valves on the wall you should be able to remove the rubber hoses right where they connect to the machine and check the water flow by directing them into a bucket or pan while you open the supply vales. If you have good pressure and flow make sure there is no debris clogging the screen, just inside there the hose connects to your machine. These can get blocked where the water won't pass or runs very slow. Sometimes it pays to check the simplest causes first. Good Luck. SS.
Q:I've been told that I need to replace a clogged expanssion valve on my '96 toyota camry.A friend said he would properly recharge the system if i replaced the parts needed .I can't ask him where it is because he's out of town for a little while. I also need to replace the drier ,but it's obvious where it is.Please help me.
the expansion valve is usually located inside the line next to the accumulator/dryer. If you drain the system, and remove the accumulator, look inside the line that leads into it, and it should be stuffed in the line. If you see one inside the line, it is actually called an orifice tube, but has the same function as an expansion valve. Actually, expansion valves are usually used in large vans with a rear a/c evaporator unit. If it is an external valve it should be next to the accumulator as well. The purpose of this valve/tube is to create high pressure gas out of low pressure liquid freon. These usually become clogged with debris after the compressor's pistons break apart and contaminate the system. If you find little metal shavings in the tube, or valve, your compressor was either replaced at one time, or is bad now.
Q:i have a 1970 chevy sb 350 and i need to set the valve lash what is the proper method and where do i start? everything is stock!
Woah, woah! You didn't say exactly what 350 you have - do you have a hydraulic lifter cam in it or is it a solid lifter cam? You cannot preload a solid lifter, and doing that with the engine running ain't that good of an idea. You need to get into the ballpark of having the proper preload in the first place in order to even do the final adjustment with an engine running, anyway. Verify what kind of lifter you have before you proceed. For a newb and for a stock engine, you really can't go wrong with the method below - it includes video assistance to help with the visual. I've adjusted hydraulic lifters on a 305 the non-running way, and on a running like the previous post mentioned, for a 350 with a performance cam. Let me tell you, even with the clips, you will make a very big mess adjusting that engine running, plus you need to be painfully careful of doing something dumb, like putting your paws near the running belts - something I wouldn't expect a newbie to feel comfortable doing. Save risking your hands for when you set the timing!
Q:I have my head off now I need to change my valves how do I do it?
The valves may not just slide right out. The keeper sometimes form a bit of a ridge on the valve.You need to remove that little ridge first if they don't just slide out. After they are out the guides may need work to achieve proper fit and centering of the valves. The valve seats may also need to be ground. Most of the time it is easiest to take the head to a machine shop for the valve work.
Q:I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.

Q:Anyone know where the pcv valve is located on a 2000 Lincoln Ls V6 3.0
It should look something like a flattened top and should be black and in line with your fuel fline to the injectors.
Q:i got a filler neck for my dodge dakota and was wondering how to put it on. can anyone send me a link or help me. and also what does my EGR valve look like and i cant seem to find a new one not even at the dealer. i was told to clean it how do i do this. can someone send me a link or pic what it look like. thanks
The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!
