- Q: I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project
- You will need a head rebuild kit: valves, valve seats, valve guides and all the seals and gaskets. You will need a valley pan gasket. Leave it to the machine shop to get all the parts that go in the head. I left out valve springs and spacers that may be worn out of spec. If you ever pulled and replaced heads, you have a good idea what you're in for. If this is your first time, get help from someone with experience so you don't end up with a basket case needing to be towed to a shop for assembly. That's a nice engine and you shouldn't try to play cheap fixing it.
- Q: What is the best procedure to check/adjust valve clearances? This engine is a perkins diesel inside of a cat generator. I know that he exhaust valve is .018 and the intake valve is .008.
- Adam S, you're both right and wrong as far as needing to adjust valves. I changed 2 shims in 100,000 miles on my Kawasaki KZ1000, but my 1300 Kaw touring bike with nearly identical valve train needs checking and adjuuting every 6,000 miles or so. Go figure. Kneedragger, since your bike requires manual adjustment, you're valve train is either going to have a rockerarm type system with threaded screws and locknuts (easy) or use shims of various thicknesses to adjust the clearance (harder). Some have the shim on top of the 'bucket that covers the valve spring. With these, you will need a small, rather inexpensive tool specifically made for your model engine to compress the spring, allowing you to remove the shim. Other engines have the shim under the bucket, requiring you to remove the camshaft to change the shim. No special tools needed here, but reinstalling the camshafts correctly is absolutely vital. While this proceduere sounds rather intimidating, just remember that checking is all that may be necessary and no adjustments will need to be made. To check clearances, the idea is to turn the camshaft to that the cam lobe is pointing away from the valve and then measure the clearance with a feeler gauge and see how that compares to the recommended clearances. On shim type, clearances nearly always tighten and if the clearance is too little, you will need to install a thinner shim. I write down the clearance for each valve each time I check the clearances. If one valve tightens up faster than the others, this will give you a heads up to a possible future problem. Or, you may find they are ok this time but at the next check, you find some that need adjustment and will decide to take it to the shop that time. After a few checks and recording the clearances, you'll get a pretty good feel for how often you need to check them again. If you decide to do it yourself, by all means, get a shop manual.
- Q: what is the average cost to replace a valve core on a car? also can any car shop do it or do i have to go to a conrads etc.
- You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.
- Q: When I flush the toilet it flushes just fine, but it doesn't fill again. You have to close the wall valve and then open it up again to fill the tank. Is this a problem with the valve or the internals of the tank? Thanks
- Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.
- Q: Hi,I have just bought a Northface Hammerhead and for some reason when biting on the bite valve no water is being released. Does anyone have any idea why this might be, or can tell that I am missing something obvious. Thanks very very much.
- Some valves are finicky as to where you bite them. Also, sometimes blowing a small puff of air into the bladder will help the water flow faster. If you can't stand the valve you have, you can buy a replacement valve from another brand and stick it on there. My favorites are the MSR and Nalgene/Jansport valves, but Camelbak isn't bad either.
- Q: I have a 96 Toyota Camry. I am putting about 4 qts. of oil in it a month. Other than this issue and some other minor things this car is in great shape. It doesn't appear to be smoking from the tailpipe and I never find any puddles of oil under the car after it has been sitting in one place for a while. What can be wrong with my car causing it to eat this much oil. Every now and then I smell a little burning oil but it is not coming from the exhaust. I'm thinking a valve job. Engine has 250,000 miles on it and it runs great other than the oil thing. I drive it 116 miles a day back and forth to work. Any suggestions??? Help!!!
- A valve job is removing the cylinder head(s) from the engine so the valves, guides and seats can be refurbished to restore compression and oil control. A valve job may be necessary by the time an engine has 80,000 or more miles on it, or to fix a burned valve, compression or oil burning problem. If the valves are to be reused, they will be inspected, checked for straightness then refaced. Many shops automatically replace all the exhaust valves to reduce the risk of failure (exhaust valves run much hotter than intakes and are much more likely to fail). On the other hand, if you have an import car with dual overhead cams, four-valves-per-cylinder and a lot of fancy valvetrain hardware, you might be looking at a total bill of $200-$300. Parts typically cost much more for import engines as well as performance engines and diesels. The labor to do the valve work is also much more involved on these overhead cam multi-valve heads. (Of course, they didn't tell you that when you bought the car. All they stressed was the fantastic performance of overhead cams and multiple valves.)
- Q: What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?Thank You !
- LP gas and natural gas work off of two different pressures. Usually there will be a inner spring that need to be changed out inside the valve, and the orifice will need to be changed as well. If you don't convert your valve, it can prove to be very dangerous! Most likely it will only have an erratic flame, and burn very dirty. The flame will burn out of control and have orange color to it. However, it could result in not burning off all of the gases as they are released, and could cause an explosion. Most of the time in the owners manual it will have step by step instructions on converting LP to Nat, or vise versa. Remember, gas is a safe alternative to electricity, but if not handled correctly it can be very dangerous. Please proceed with care, or if you are uncertain with yourself, call a qualified technician. It shouldn't take em more than an hour, and most techs charge around 60 bucks an hour. A cheap price for a job done safely.
- Q: ok im buying a kx 125 from 96 and he said the only problem with the bike is that it has a small oil leak around the power valve too me it sounds like a gasket. but i want someone elses opinion on what else it could be.
- The kx125 actually has 3 valves in the exhaust, a main, a left-hand one and a right-hand one. Each is fitted with o-rings which require disassembly in order to be reached. This would also be a good time to clean the power valves since they tend to become encrusted with carbon deposits which interfere with their normal operation.
- Q: I was diagnosed with Mitral Valve Prolapse when I was 18. I am 23 now and feel like my symptoms have only gotten worse. Sometimes I could just be still and have severe chest pains with slight paralysis in my arms. It's like my body locks up from the pain. Recently I had an episode and I immediately started crying from 3 seconds of severe chest pain. For the past three days I've had this headache in my temples that sends a slight numbness down my jaw. I didn't know if these symptoms were in any way related to my MVP. I'm going to see the doctor today and plan on mentioning it. Does anyone have these same symptoms or an idea of what is wrong?Thank you!
- Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
- Q: fisher control valve
- For any pnuematic control valve the operating pressure is from 3 to fully opened at 15 psig. It means a pnuematic control valve opens fully at 15 psi and closes at 3 psig. To calibrate it,prepare the following, one mercury manometer 0 tp 1000mm,Hg, one air pressure regulator for 20psig supply and air hoses,3 to15 psi output gauge, micrometer screw pressure regulator and air pressure supply. Prepare a Tee with the air supply at the center.Connect one leg to the mercury manometer and the other equalizer leg to the control valve and a tee on top of the valve and an output gauge connected to the tee.. Both the manometer and control valve should receive equal pressure from the pressure regulator. A 15psig pressure is 775 mm mercury . So, set the mercury manometer to an equivalent of 15 psig,775mmHg, and prepare a table of equivalent pressure from 3, 6, 9, 12 and 15psig. The valve should be fifty percent open at 9 psig and 25% open at 6 psig, likewise, it should close at 3 psig and 75% open at 12 psig fully opened at 15 psig. The pressure variation may be done with the micrometer type pressure regulator at the pressure supply.
