Q: looking to get a greddy type rs blwout valve for my sti, but i wana noe wut exactly da blowut valve does....kause i just got da car and i bought warranty, and i wana make sure ma warranyt doesnt void.....and how hard would it be to change da blowout valves....frum ma old 1 to dis new 1......so just incase ma warranty does void kause of da blwout valve wenneva i have problems i could switch it back to da original 1HELPPP???: First I wouldn't purchase the Greddy, I had the former Type-S and it tended to leak on my 02 WRX. I would look at getting something like the HKS SSQV it is one of the most efficient valves out there, and if you don't like the chirp it makes you can purchase an insert that is a woosh of air. As far as what a Blow Off Valve does... When you throttle plate closes after boosting, your charge pipe(between the turbo outlet and the throttle) has leftover boost pressure. This pressure will push back on the turbo and possibly harm it. Factory this pressure is re-routed to the intake, an aftermarket BOV vents this into the atmosphere, making the desired noise. Yous can get valves that do 1/2 vent and 1/2 re-circulate. With a cheaper valve like the Greddy the vent into the atmosphere is going to cause the car to stumble between shifts, this is because the valve is inefficient and causes the vehicle to run rich. As far as Warranty goes, it is illegal for a car manufacturer to void a warranty do to usage of parts other than theirs. BUT if you need warranty work and they can without a doubt prove that the Blow Of Valve caused the damage they will make you pay for that damage. Tial is awesome, but fitment on TMIC would be an issue.

Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous: its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .

Q: For example, 2 valves from the modular 4.6 is equivalent to 1 valve from the LS1 which is a bigger valve.: OHC generally have 2 small valves instead of 1 large valve operated by a push rod. The aim is to have the most flow possible and the least mass of valve. (avoid valve float) I cannot say anything about specifics

Q: Liquid propane leaving the reflux pump of a distillation column flows through a 3.5 in ID pipe at a flowrate of 90 lbm/s. There is a flowrate control valve in this line, and it is set such that the pressure drop across the valve (delta)P=15 lbf/in^2. Upstream of the valve , the pressure P1=18 bar and the temperature T1=310 K. Assume there is negligible heat transfer with the surroundings and that the density of the liquid does not change significantly.a) What is the kinetic energy change across the valve?b) What is the enthalpy change across the valve?c) What is the temperature change across the valve?d) What is the entropy change across the valve?: If there is NO change in the density of liquid propane as it passes through the valve, and if the size (area) of the pipe upstream and downstream of the valve is the same, then a) there will be no change in the velocity of propane, hence there will be no kinetic energy change. b) this is a process of throttling, with no change in kinetic energy, hence there is no change in the enthalpy. c) temperature change can be determined using the detailed property table of propane, but if it is an almost-incompressible liquid, then this too, will be negligible. d) dh = T ds + v dp. Since there is no change in h, integrate this along a constant h line from inlet to exit (upstream to downstream) and you will get ds = -(v/T) dp. Since p reduces from inlet to exit, the change in entropy will be positive. This is as expected. If we assume density (=1/v) and temperature (T) to remain constant, then the change in entropy will be s_downstream - s_upstream = (p_upstream - p_downstream) v /T.

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: We have a main gas valve outside and there's a gas valve by out air condition and we want to know which way if off and on .. Does anybody know !!!: Generally speaking the valve has a handle that pivots from parallel, to perpendicular. Open is in line, or parallel. Closed is perpendicular. If it's a rotating handle, then the valve stem will be all the way in when closed, or all the way out when open. The valve stem is located in the center of the wheel that you would turn. Hope that works for you.

Q: As title.What's an easy way to remember: mitral valve leaflets are anterior and posterior leaflets; tricuspid leaflets are anterior, posterior, and septal (medial); aortic valve leaflets are left, right, posterior leaflets; pulmonary valve leaflets are left, right, anterior leaflets?It's easy to remember all but one valve (mitral) have three leaflets each. Physically aortic root sits behind pulmonary trunk, I guess that makes it easy to remember aortic valve has left, right, Posterior; and that pulmonary valve has left, right, anterior leaflets. Where I'm running out of ideas now is how to remember tricuspid has anterior, posterior and septal leaflets... Please help.Thanks.: The tricuspid valve has three leaflets which are thin and membranous with commissures that appear more like indentations than true commissures. The TV apparatus is similar to the mitral valve but has greater variability and thinner leaflets. The three leaflets are the anterior, septal and posterior leaflets, with the anterior and septal being larger than the posterior leaflet. TV= tricuspid valve tri-cuspid=3(three leaflets) leaflets=3leaflets Tricuspid: Having three flaps or cusps. The valve that is called the tricuspid valve is situated between the right atrium and right ventricle and permits blood to flow only from the atrium into the ventricle. The aortic valve in the heart also has three cusps. Tricuspid valve (Anat.), the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; -- sometimes called the tricuspid valves, each flap being regarded as a valve. Take care as always

Q: Do most V6's have 24 valves? What are they for? (brief description would be fine): V6 Dohc 24 Valve

Q: If someone is not born with heart valve disease... can a teenager or a 12 year old develop heart valve disease?: If a teen has heart valve disease, is most likely something they where born with, but it can go undiagnosed till the are teens. I was born with aortic stenosis, aortic regurgitation, bicuspid aortic valve(all are valve disease) and i also have an enlarged aorta. Im 16 years old. I was born with the bicuspid aortic valve and aortic stenosis, and that caused me to develop aortic regurgitation when i was 10, and an enlarged aorta at 14. In some cases a teen can develop it with out being born with it, its uncommon but it can happen.

Q: How hard would it be to fix an EGR valve on a 1990 Geo Storm that is stuck open? if not fixable, how much would it cost to replace it, or have it replaced by a professional?: First, okorder /... I see that Autozone doesn't have that part, but it does mention there are 3 different possible part #'s, depending if it's a 2+2 or GSI, and/or Transmission type, so keep that in mind if you need to order a new one.
