Q:is a 4 cylinder 16 valve.... 5 stars for the best answer....: junkyard

Q:I was wondering if anyone knew how important tire valve stem caps were in maintaining inflation pressure in auto tires? I noticed one of my tires losing air slowly (from 30 psi to 21 psi in about a week) and this tire (unlike the other three) also had a missing tire valve stem cap. I've just replaced it, and was wondering if a missing valve stem cap caused faster loss of tire pressure.: The valve caps main purpose is o keep dirt/debris out of the valve stem. if the valve inside were to leak due to not being tight or dirt holding it open the cap may prevent leaks. but if you refill that tire once a week, the dirt would have been forced in. replace the cap and see what happens. check the tire and valve stem with soapy water to help find the leak.

Q:When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!: A valve reduces the cross-section of the pipe. .

Q:The diablo tunner says you can cut off your EGR valve, only if your going to take it off. What effect will this have on the car?: The EGR valve or Exhaust gas Recirculation valve is located on the exhaust equipment. those often get hung up with rust and different exhaust deposits. The motor vehicle may be under production facility guarantee being basically 3 years old. i might verify with a broker to work out if the motor vehicle and/or section remains under guarantee. A defective EGR valve will reason the workstation to make the incorrect settings to the gas and air blend inflicting the engine to run too rich or too lean. Its no longer too unfavourable interior the quick term, yet your gas mielage will go through, and you will be able to fail a state inspection so get it repaired before then.

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: believe it or not a desmodromic valve adjustment takes like 8 hours.So its kinda costly to do that job.

Q:I am looking at buying a 2001 Pontiac Bonneville and the guy said the car's check engine light says it had a problem with the EGR valve and so he bipassed it somehow. He said a EGR valve isn't needed. Is this valve very important or needed? What does it do? Thanks: You need an EGR (exhaust gas recirculation) valve. You can bypass it temporarily but your gas mileage will suffer and the check engine light will remain lit. They are usually located near or under the intake assembly are are easy to change. You will need to reverse the bypass that he did so ask him how he did it.

Q:I have a lawn tractor with a 10 hp Tecumseh and its running so rich because of the carburetor float valve not seating. So how should I fix this?: A disfunctional float valve will cause the carburetor to flood from fuel spilling over the top of the float bowl. The float valve acts like a toilet valve and just fills the float bowl up to the top and closes until the level drops from the fuel evaporation being pulled off while running. I don't know the exact specs, but you should be able to guesstimate and adjust by bending the float tang, or just replace the float valve.

Q:I'm thinking of buying a used 2006 Volkswagen Jetta. It has a 1.5 liter 20 valve engine, and I really don't know what that means. That's good, right?And is this a good used car to buy?: Most okorder , and check the service records for the car you are interested in buying.

Q:behind the valve cover of the #1 and #2 cylinder there are 2 intake and 2 exhaust valves I need know (cylinder #1) which is the intake and which is the exhaust. thank you in advance.: 1. Intake valves are usually larger than exhaust valves 2. Exhaust valves are on the same side as the exhaust manifold

Q:I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?: === take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
