Q: Between these two Blow off valves around the same price, what would be the best choice for a pt cruiser.: The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.

Q: Among butterfly,ball,needle and gate valves which is used mostly in pneumatic system?: It depends on what sort of system you are operating. Most butterfly valves leak, a few don't. Ball valves are instant operation, and don't normally leak. Needle valves are used for fine control of the flow rate. Gate valves are quick to operate, and don't normally leak. On aircraft pneumatic systems, butterfly valves are common, where a leak is permissable. Where no leak is permissable, slide valves are used, which have rubber seals.

Q: Hi,I have a 2002 Honda Accord with 115k miles which recently gave a ECL. The Honda dealer identified this a P1457 and says that the EVAP bypass solenoid valve needs to be replaced1) is this referring to this valve?: P1457 Honda Accord 2002

Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?: This is a common problem. Don't force/twist them or they could break off. You will need to shut of water to your house [assume it is a single family?] The shut off is frequently in the front of the house where the water enters and could be under a hose bib [outlet]. Don't confuse the water shut off handle with the water pressure regulator, a dome shaped metal cylinder attached to the incoming water pipe. If you can't find the shut off there is usually one on the water utility's side of the water meter - closest to the street or road and sometimes one just on the outlet side of the water meter that you can twist by hand. After shutting of the main water supply to the house relieve pressure at a low point - usually a hose outlet. This way when you remove the water supply valve under the sink you won't get a cascade of water. You may want to douse the shut off [sometimes called angle stops] with some penetrant like PB Blaster penetrant and let it sit. You may want to purchase 1/4 turn ball style shut off valves as opposed to the twist or gate style. Note the size inlet, IPS 1/2 inch, 3/4 etc. and the outlet size, generally 3/8' for new faucets. Take a photo with your phone or a digital camera and take it to the store when you purchase new shut off valves. If you have a dishwasher and the water supply goes to the hot valve, then be certain to get a shut off valve with two outlets and use it on the hot side. If you are in a condo or multi-family you will need their permission to shut off the water unless each unit has it's own shut off [more typical of town house style than apt style condos.]

Q: How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?: where is i get the packing gland material

Q: I have replaced the rubber washer in the valve and when I pull up on the float arm everything seems to stop then shortly thereafter air bubbles start coming out of the bottom of the fill tube. How could air be getting thru the valve without water which would cause the shutoff valve to tighten?: This okorder /

Q: We've got a one-handled faucet for the tub/shower and it has that pressure-balancing mechanism. We have it set, I think, so that we can take the hottest showers possible, because our water heater lacks enthusiasm. However, when I want to draw a bath for the baby, I need it to be lukewarm - and I have to turn it almost OFF to get the water to be even tepid. I can't get cold water out unless it's only trickling. As far as I can tell, our cold water pressure isn't different from the hot (bathroom faucets are 2 handles and H C seem to be about the same pressure). Is there a way to adjust the valve in the shower so I can get both the hottest possible, and the coldest possible water at full pressure?: All major manufactures of valves have excellent customer service departments. Most of them also have great websites with lots of technical info. Note: You may try changing your shower head to one that is a higher flow or remove any flow restrictor that may be in the one you have now. This may allow you to have the valve set to a colder setting for the tub spout and should increase the hot when showering. Personally, I don't like these style valves. Too many problems like yours.

Q: When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?: the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).

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: I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.: Creating a proper valve system for the creation of a diving lung is not as simple as you think. You require carefully balanced directional pressure regulation valves. A simple one-way valve (AKA check valve) would remain open and release all the air from the airbag as soon as the airbag was subjected to water pressure.
