Q: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?: Yes okorder /

Q: non-return valves: ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.

Q: What are a sing of a bad Idle control valve, will this cause bad mpg?: No, the valve is there to provide a steady idle regardless whether the transmission is in gear or the air conditioner kicks on. If the Idle Air Control (IAC) valve is not working right the engine will usually idle low and try to stall, although it can also cause high idle.

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: 1990 5.7l with a .470 lift cam , is there going to be a clearance issue between the valve guide and the valve. Is the rocker going to bottom out on the guides and bust my heads.. If so what should i do.: Get yourself a degree wheel and check. A valve stem usually has about 1-1/2 thousandths of an inch of clearance between it and the guide to allow movement and lubrication. Your camshaft has no bearing on this clearance. If you want a wild guess as to whether or not you might get coil bind in the springs, rocker bind against the rocker stud or even valve spring retainer smashing into the top of the valve seal then my guess is not, not with just .470 lift. Probably would take more like .500 for any of that to happen.

Q: I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:: A blow off valve releases the air into the atmosphere which gives you the noise their known for. A bypass valve releases the air back into the intake, like a stock BOV on most turbo cars including the WRX they are also known as recirculating BOV's, and do not produce the sound that a atmospheric BOV will make. A recirculating BOV will not cause you to run rich, and thats why a lot of people recommend them unless you are running a bigger turbo/ lots of boost. However they do not always make you run rich, and i would suggest that if you do get an BOV to just install it and not mess with it. If you mess around with the spring on them it can cause compressor surge which you do not want. However, I have used the hks ssqv with none of these problems.

Q: I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work): Get a straw and put it in a glass of water. Suck the water up the straw and what happens? Get that same straw and punch 6 holes in the center around the straw. Suck on the straw and what happens? That is the purpose of the bypass. Now the speculation behind the bypass is the intake system has to be fully submerged for it to work efficiently. Get your aftermarket straw and hold it sideways nearly touching the top of the water and suck real hard. You will notice water gets to your mouth, and so your engine. Nothing more than a pressure differential. Bypass valves are very expensive parts for people that don't understand principles of pressure and vacuum. Don't waste your money on it, but stay out of deep puddles.

Q: what exactly is thc pcv valve and what does it do: i don't know much about them. i had to get one replaced in my car a few weeks ago.. i knew i had to replace it bc my car made a farting noise whenever i turned left.....

Q: I have recently been diagnosed with Endometriosis within the last 2 years. I have also had Mitral Valve Prolapse (MVP) for the past 10 years. ... Anyways... I was reading in a brochure for Endometrosis that there is a commonality between having those two diseases. If you know of the reasoning behind this I would be very interested in knowing. As I have yet to find an answer yet. I am just curious why having one will give you a larger likley hood to get the other. Thanks for your time and answers!: I went to see an herbalist and when she heard that I had MVP the first question she asked was did I have endometriosis as well. She asked only to confirm and to state that she had ZERO female patients with MVP that did not also have endometriosis. I can tell you that since menopause, the endometriosis has been unnoticeable, but the MVP has gone from mild to moderate. I monitor my body better than most because of an autoimmune disorder. I do not doubt that there is a connection.

Q: i have an old 79 malibu and its only got a 267 in it. I wouldnt buy new valve covers because its not worth it to me but i was thinking i could clean the ones i got up a little bit. i was thinking of painting them. What kind of paint should i use? and one other thing is the gaskets. I figure while i have them pulled off i should put new gaskets on. I read up about getting all the old stuff off but i was curious still about it. I was just looking at some average ones made of cork for 10 bucks. Do i lay the sealer downthen put the gasket on , then put the valve cover on?: I would use Chevy orange heat resistant paint for the covers and as far as the gasket, when you do pull off the valve covers, you will have to clean the surfaces with a PLASTIC putty knife and maybe steel wool to smooth it out fine. DO NOT use anything metal on these surfaces as you might gouge it. Whatever you do, make sure you put rags over or inside the camshaft/valve assembly so you do not get any gasket pieces in the valves because you will have REAL problems then......Depending what kind of gasket (aftermarket) is made for your car, if it is cork, you will want to put gasket sealer on the gasket (Both Sides) first, and then place it on the surface and then put the cover on. Make sure that when you tighten the bolts, they should be torqued to specifications of your car. And if you go ahead and tighten them without a Torque Wrench, just make sure you criss-cross tighten, starting from the corners and working opposite and DO NOT over-tighten !!!!! I would strongly recommend that you torque them to whatever inch-pounds !!!!
