- 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:
- They guy above has some of it. The reason it runs rich is because when the stock by pass valve releases the air back into the intake, it does this after the MAF sensor. Since it is getting a big surge of extra air that the MAF does not read, the ECU automatically increases fuel for a split second when the BPV releases. When you suddenly release all that air into the atmosphere, the computer does not know it and still ups the fuel. That seems like not a big deal but it runs really hot and can do things like foul up plugs and even melt the catalytic converter. There is also the issue with most aftermarket units causing stalling when you first step on the gas or even when sitting still. If you want a little noise, I would first look to getting rid of the intake silencer in the fender. It looks like a milk jug. If that's not enough, then look into an open ended intake. Just be careful with intakes as they also can cause issues depending on the brand and they rear of the car. At least an intake ca be tuned for though. The issues with a BOV can be reduced a little with tuning but can not be eliminated. Sow know that you know the risks and how it does absolutely zero to benefit the car, spend the money on something better.
- Q:what would happen if valve was not adjusted right? and please explain
- it could make a hole in your piston
- Q:Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!
- 1. Would require dysfunction on a valve in the right heart generally speaking, so the options would be the likes of tricuspid regurgitation or stenosis, or even pulmonary stenosis. 2. PND is a result of heart failure, particularly regarding the left side of the heart (although of course both sides could be failing). Many valve problems could cause this as an end result... a bit of an odd question, but I'd go with mitral stenosis or regurgitation primarily. 3. Congested liver is the systemic blood system overload (like the oedema), so it is the right heart. Triscuspid regurgitation can cause a congested liver and if you felt this liver, it would be pulsating too. 4. Distended jugular veins are a sign of heart failure. Primarily right heart failure as it is causing blood to be backed up instead of passing through the right heart to the lungs. Tricuspid stenosis or plain old right heart failure (with or without left heart failure at the same time). 5. This is typical of left heart failure as blood backs up into the pulmonary system as the left heart is failing to pump into the systemic circulation. Similar things to PND can cause this. These questions though, are honestly a little on the vague side and half those cases would result from heart failure even without any valvular abnormalities...
- Q:I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
- Getting a vlave job done isnt going to hurt your car at all, nor your motor. Make sure you have a reputable machine shop do this (most garages dont have the tools for it). If a 3 angle valve job is done correctly and new valve stem seals, retainers, and spring are all carefully installed to manufacturer spec then there should be no problem at all. Many shops will do a sloppy job grinding the valve face (which is a hard thing to get the knack for) and will install to valves without another thought. When new valves or old valves with resurfaced faces are installed the spring rate of the valve springs needs to be checked to ensure are srpings are the same strength. Also once installed, the height of each installed valve/spring needs to be checked to make sure its in the specified allowance. If valve seats and surfaces are all done correctly along with a profesional installation I wouldn't worry!
- Q:Is it safe to remove the butterfly valve on my 94 celica 1.8l st?
- no theres a reason its there,, to regulate air flow...without it your car will get poor preformance..
- Q:Okay I know lots of people wonder what is better presta or schrader...well I realy don't. My bike was made for presta and thats what I have a question about. So I just got my bike back after is being stored away for a few years, so yeah it was neglected. Question is now that I am doing a tuneup on it I found out the valve came out of the tube. I don't know if that is normal and if I am able to put it back in. It looks like there made for the valve not to come out but I just want to make sure before I go out and buy a new tube. Hope you can help. Thanks. -Sarge
- Some okorder / but tubes are cheap and if your bike has been in storage for a few years, why take a chance. Better a new more reliable tube than having to fix a flat because your stem came out or your tube let go because of old age.
- Q:i hav no clue wat it is or what it does, but i was goin to buy an 08 mitsubishi lancer but then i read that the valve guides in mitsubishi engines wear out really fast and it causes some problems.what kinds of problems?how will this effect the car?Should i go ahead and buy the car?
- you will burn oil, if you think it may be a bad deal look for something else. plenty of cars out their to choose from. good luck! it will give you poor gas milage, and burn up o2 sensors also.
- Q:My 99 accord has been smoking bluish white smoke out of the exhaust only at high RPMS- 5000 and up, but NOT at lower RPMS. Obviously I rarely go that high, but I've feared the worst. I've checked the coolant, its green without contamination. today a mechanic discovered that someone installed the wrong pcv valve on the car- the one that belongs on the v6 model, and that it is somehow larger. the mechanic suggested it was possible that this was the cause of the smoke- the oil was getting into the intake manfold, and into the cat, and that when the engine is at higher rpms, and the gases/ heat increase, it burns up the oil in the manifold/cat. He said IF that is the cause it should clear up in a week or so. Does this sound to good to be true? or is it possible? the car does have 160,000 on it, but i've owned several hondas with much more mileage that didn't smoke at all.
- The PCV valve is a possibility but the more probable cause on your car is that the spark plug tube seals are leaking oil. The 4 cylinder hondas have tubes that surround the spark plugs that run from the valve cover to the top of the cylinder head. There are gaskets on the valve cover to keep oil from getting into the tube from the top and seals at the bottom to keep oil from getting into the tubes from the bottom. on older hondas the tubes fill up with oil and the oil works its way into the engine combustion chambers through the spark plug threads. its real easy to see if this is the problem. Usually you can just pull each of the spark plug wires off. If the end of the spark plug wire is wet then you have leaking tube seals. Typically the seals on the valve cover can be replaced for about $50. if it requires the lower seals its pretty pricy. I think that's what you're going to find. PCV failures are rare as are valve seal leaks or internal engine wear problems on hondas. hope that helps hope that helps
- Q:Im trying to replace the egr valve on a 97 lincoln continental. I need to find out what size wrench I need, to get the nut off. Do you know?
- I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.
- Q:what is the difference between the pinch valve and gate valve / knife valve? If someone can help me explain / show me the complete structure of pinch valve and the way it operates, thats better
- a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.
