- Q:I just found out about my condition. Is it dangerous? And will I need surgery? My mom just got her monocuspid valve replaced. I don't wanna have to go through the same thing. And will I still be able to go on rollercoasters? I'm going to cedar point tomorrow. I only want answers from people who know exactly what there talking about thanks
- Yes you might have constantly had this, it is some thing you had been born with. A natural aortic valve is tricuspid, that's it has 3 final flaps, however a bicuspid valve best has 2 flaps. Sometimes those bicuspid valves provide no issues, however in a few individuals they are able to result in center murmur later in lifestyles ( mostly on your 30s or 40s ) in view that they enable somewhat blood to leak again the flawed manner while they're closed. If this will get extreme sufficient, you can also want surgical procedure to suit a man-made valve. This is lovely ordinary at the moment and now not some thing to fear approximately.
- Q:I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
- Buy a compressed air tank that you can fill at a gas station like you would air up a tire. Mount this tank in your trunk and route air hose from the trunk through the passenger compartment and into the engine compartment. Add a simple valve in your center console or wherever you prefer to turn the air on or off. Drill a hole though your hood and affix the air hose to it. With the air tank filled up, just open the valve and WHOOSH, instant blow off valve sound. You could even fill the hose with confetti for a colorful display. If you wanted to get real fancy you could rig up an electric air compressor under your hood for a continuous air supply. Thats the only way you cant get the release of compressed air to make a blow off valve sound without a turbo. Oh, and while you buying all the supplies for this don't forget to get some fake spinner bling-bling hub caps!! Then you will have the ultimate pimped out ride!
- Q:My AC leaks and mechanic says it is shrader valve. Is it expensive?
- No okorder /
- Q:i ha valveve a knock on the driver side .and i have to remove the intake manafold to get to the valve
- valves don't knock and you can't get to them through the inlet manifold if it's the lifter you may be able to get it by taking the valve cover off but even then you sometimes can't and have to remove the camshaft
- Q:I really like the sound that a blow-off valve makes when they are in audi tts. So I was wondering if I got one for my '02 225hp Audi tt if it would damage the engine in any way. I have read that diverter valves are better, but I want the sound of the blow-off valve. Also any recommendations on blow-off/diverter valves would be great.
- Well, in the audi system it expects to get the extra boost back from the diverter valve so it would be against your best interest to blow off all the boost. However, they do make blow off valves that sound great but only lose 10-30% of the boost which would have little to no effect on the car and you still get that cool sound. I personally am not into blow off valves so I've never bought one but I've heard some good things about Forge blow off valves and I believe they make a 30% blow off like what you would want.
- Q:My husband just found out that one of the heart valves is 100% blocked and the other 3 are 90% or more blocked . He is 78 years old he Is nearly non mobile. What kind of treatment would you suggest?
- A heart valve can't be 100% blocked. The heart simply couldn't function. On the other hand, coronary arteries can be blocked as you described. Normally, 4 vessel disease is treated with bypass surgery. In a high risk patient, angioplasty might be an option. However, if he is not having cardiac symptoms , or if he is thought to be TOO high risk, the option is medical treatment. Sit down for a talk with his cardiologist.
- Q:so, im a day away from getting a 2002 748 and im super excited, iv always wanted a ducati, and i cant wait to have one of my own. i understand that ducks have a reputation of breaking and im prepared for it. I also understand the valves need to be adjusted every 50-100 feet :P all kidding aside i know every 6k miles they need to be adjusted. i dont know however how much it costs to have the valves adjusted. im sure it varys from shop to shop but a ball park quote would be really helpful just so its not a kick in the gut when i take it in for the first time. thanks
- Well first, you need to get them inspected, and they'll only adjust the valves if it's needed, even at 6k mile intervals, if your valves are still in spec or very close without lobe drag, they probably won't be changed, so check your bill and ask your tech directly if they were changed, some less reputable dealers may try to pull a fast one on you. If you actually needed ALL 16 shims changed, you're easily talking $1000 in labor, esp. on the 748/916 style heads, which have access ports on the heads instead of being able to remove the whole top of the heads like the newer DESMOQUATTRO heads, and are a PITA to work on because of it. The bad thing is that until recently (and they still need improvement) Ducati's quality control is lower than other manufacturers, meaning very inconsistent performance reliability, just from variances in manufacturing. If you get a GOOD tech to do the bike right in the first place though, not just valves but all-important TPS resetting, cam timing/belt tension, and balanced CO's in your exhaust, you will have a lot less headaches with your Duc.
- Q:what is the average cost to replace a valve core on a car? also can any car shop do it or do i have to go to a conrads etc.
- You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.
- Q:Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?
- Head gaskets are made of metal.Valve covers gaskets are made of cork.
- Q:Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
