- Q:hii have just found out i have a genetic disease called multi valve prolapse but i want more info about itwhat are the symptoms? can it kill me? any info will help!!thank you
- Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
- Q:Ok, I recent rebuilt a set of vortec heads, but the valves I got are a bit longer than stock, I believe .1 competition products pn I2552P. I also installed howards cam 98214 springs with 10° locks and retainers, the locks are +.035. I was just wondering if I would have enough spring pressure.
- I would be worried more about your geometry right now than spring pressure. Your saying the valves are .1 longer? Thats quite a bit.
- Q:12 valve
- Un plug the vacuum hose on top of the valve, loosen and remove the big tube nut on the bottom of the valve, I have found if you hit it sharply with a hammer 3 or 4 times before you try to loosen it won't break the valve off, once the tube nut is undone remove the 2 bolts holding the EGR valve to the intake manifold. Remove and discard the gasket and install the new valve in the reverse order. If the tube nut still won't come loose try heating it with a torch, if it's really rusted on you might have to replace the EGR tub along with the valve.
- Q:Hi, i bought an xr250r 2002 model. I rebuilt the engine and put in new exhaust valves. After i did this proper compression in the motor came back and it wasnt blowing smoke anymore. I took it for a 'run-in' ride, and noticed that the engine was quite noisy. I guessed it was the valves needing adjusting. I got numbers for the valve clearences which were: .004 of in inch for the exhaust valves and .005 of an inch for the air intake. Now i have done this the compression in the bike is enormous, it is barely possible to kick over, and the motor is very noisy, there is a loud ticking noise which im guessing is still the valves. Is all this normal considering i have just rebuilt the engine, put in new valves and hardly ridden (one 50km ride)? I would like to keep riding it to run it better to see if the motor loosens up, but im scared to ride it as it is. Any advice would be greatly appreciated.
- .004 is a bit tight for an exhaust valve? usually this is nearer 10 thou. It is better to have slightly larger clearances to the tappets/ valves than to be too tight and risk burning your valves. You do not mention the decompressor! I'm sure your bike should have a manual decompression lever if not an auto retard unit on the cam shaft to allow you to atleast crank the engine up to TDC on the compression stroke. I suspect that is where the noise problem is coming from, either that or you might be one tooth out on your cam shaft gear allowing the piston crown to kiss the valve when it is open...hence explaining the very hard to turn over!! but see my other comment too! What ever It is time to remove the inspection covers and re examine the whole set up. BTW the bike should be an UTTER PIG to kick over compression without a decompressor!! as it has a very high compresion ratio. expect to be standing up on the kick start if you are less than 160 lb (11 stone) 78 kg
- Q:hello my names matt and i have a 1997 eclipse 2.0 non turbo with 94k miles and the semi circul seal on my valve cover gasket has a small leak that i see oil dripping and i dont think the pcv valve has ever bin replaced could any of those cause my exhaust to burn oil maby a bad fuel injector? theres no oil in the top of the engine on the spark plugs when i check them all, the piston rings and the headgasket r not worn or cracked so idk what it could be some one please help
- the valve stem seals are common leak on these I work with a lot of mitsubishi's
- Q:Do blow off valves serve any purpose besides making the hiss when you shift? how much does one cost?
- Blow off valve or dump valves are used on cars with large turbos. Their function is to keep the turbo spinning during gear changes or on the over-run. Because they are driven by the exhaust gas the turbo has a lag (delay), it takes time so spin up or slow down compared to the engine speed. The bigger the turbo in relation to the engine, the bigger the lag. By dumping the excess pressure it keeps the turbo spinning reducing the lag when you get back on the throttle. It will have no effect on power on small turbos so all these boy racers you see in civics have wasted their time and money. PS The noise it makes, I think is PTCHOO!

- Q:Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?
- Head gasket is between the head and block. It's primary job is to cushion between the two, dealing with high temperature and pressures of combustion process. So it helps in maintaining combustion chamber pressure, sealing coolant, sealing oil passages between the two parts (head block). Requires major disassembly to replace if needed, and may only be part of a larger looming problem in the motor. Valve cover gasket is between top of head and valve cover. For your Honda, it involves a large rubber/neoprene o-ring that fits in a groove channel in the valve cover, specially formed for the shape of it. Also with it, should change out the other smaller seals that go around the spark plug tuges, and valve cover hold-down studs. If you have oil leaking around the outside edge of the valve cover and in the spark plug wire tubes, you can buy the set and have it easily replaced or do yourself if have the tools skill.
- Q:what are the best aorta heart valves. mech. or animal.
- It really depends on the age of the recipient. Mechanical valves last much longer but require blood thinner treatment for life to prevent strokes which has risks and is a pain and most would like to not take blood thinngers. Biological made from pig and cows and cadavers mean people can go back to their lives with no blood thinners. But, they wear out and last depeding around 10-15 years. Most do not want another open heart surgery. It is a conversation between the surgeon, cardiologist, patient and family. A young person, the no-brainer is mechanical if they can maintain blood thinner compliance. An older person would want a tissue valve with less chance of outlving it and requiring another openheart surgery. And perhaps at an age where the surgery wouldnt be done. So the best choice is based on age and what the patient wants. Arnold Schwarnegger chose a tissue valve even though it will wear out before he dies statistically and require a replacement but he didnt want to be on blood thinners. Putting a tissue valve in a 20 year old, then replacing it at 35 with another, then again at 50 and then at 65. Doesnt make sense and the scar tissue from it all. If that doesnt make sense A mechanical valve in an 80 year old and then the risk of a blood thinner and bleeding issues doesnt make sense either. Hope that makes sense
- Q:I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.
- It does actually no longer something stable on your motor vehicle except you push 20 lbs of advance. it is going to truly make you run wealthy between shifts and could additionally provide you idle issues. our first improvements could be suspension. the vehicle handles properly inventory so getting better it will make the vehicle fell extraordinary. i'm assuming you're new to turbocharged automobiles so i might advise analyzing up on sites like I-club or NASIOC and learn as much as you may in the previous you initiate enhancing and blow your motor. It happens each and all the time so i'm no longer exaggerating.
