Q: I saw some other answers. I figure the relief valve needs replacing, ok no problem, but exactly how much pressure are we talking about here? what is the correct procedure to shut this thing down to replace the valve?: Shut of gas or electric and water feed valve to tank. Open hot water faucet to relieve pressure then close faucet. Connect hose to drain at bottom of heater and open drain. Put teflon tape on new relief valve. Loosen relief valve to introduce air so water drains out. It is possible to do this on the fly by removing old valve and installing new one immediately. If your not that confident, you can just loosen old valve by hand to the point that you have just a couple of threads holding it in place. You will hear air sucking in. The tank only needs to be drained to below the level of the relief valve.

Q: It is burning oil, so that means oil is getting into the combustion chambers....but im not exactly sure which piece has gone bad? or for that matter what the valve guides are in the first place. Could the lifters have gone bad too? Can someone tell me what piece is most likely the cause for the oil leak into the chambers and then a price of how much it would cost to have it fixed. When i start the car it blows a puff and then settles down and then when im at a stop light and push the accelerator it blows a puff and then more or less settles down...sometimes it keeps going for a while. My mechanic put an additive in the oil called stop the smoke or something, and i know that that causes the seals to expand...and it has helped. So. I need someone to give me an overall diagnosis and price range. My mechanic is reluctant to have me do the work, im guessing cause its expensive...but i would rather pay 1000 dollars then buy a new car.: Do a compression test, that'll tell you exactly whats wrong. Or have a mechanic do one.

Q: I have a 2006 saturn vue that has a valve tap in the engine. The car has about 100k miles on it now. I'm the original owner of the car, and I've had the problem with the valve tap since about 50k miles, and even when taking it to saturn dealerships, I was told it was nothing and the car was fine. Now that I know what it is (I took it to another mechanic that was a friend who went over it with a 'fine tooth comb') I ahve done research and know what can go wrong a little too late :(So my question: My car only makes the tapping sound for about 5 or so minutes when i turn the car on, then it goes away and you can't hear it anymore, is this usual for a valve tap?: you sure if its valves or lifters? valves will cause a lot more problems than just a tap. lifters on the other hand will cause a noise but usually no major damage if its just a tap. lifters in a modern engine are pressurized with engine oil to fill the clearance between the lifters and the camshaft to ensure proper valve opening. if the lifter has a clogged oil port then no or little oil can enter the lifter, causing a gap between the lifter and camshaft. even a small gap will cause a noticeable noise, especially when the oil is cold and thick at start up. its a saturn so its most likely an overhead cam setup, try a high quality oil treatment and a little thicker oil. if it keeps happening then listen to the lower half of the engine. if its louder down there then you have more problems than valves.

Q: I have a 1987 Chevy Blazer with a 5.7 liter 350 engine. Where is the PCV valve located on it?: My guess would be in one of your valve covers,Look for the black hose hooked to it.

Q: Exactly what is an EGR valve where is it located?: In todays engines , fuel economy is a big issue. An exhaust Gas valve will do the following. At cruise speed, when there is not as much load on the engine the fuel mixture will lean out to save on fuel emissions, but the combustion temp will rise with a lean mix, so to control this the egr valve will throttle exhaust gas into the intake air leaning out the air and lowering the combustion temp. exhaust gas will not burn again! its burnt already, mechanical valves were easy to check with a vacum pump. but newer valves are controled by the engine control system and you should consult your service manual for proper inspection procedures

Q: I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e.g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one of those bypass valves?I'm looking for any alternatives, instead of those AEM bypass valves and was wondering if drilling a small hole in the cold air intake could help in preventing hydrolock, just as good as the AEM bypass valve.: By far the safest and most sensible way is to stick with the cold air intake that came with the car. You can't buy a better one for less than $1000 anyway. The stock intake has preheat to warm up the engine more quickly, improving fuel economy, and has been tested with the actual car model to minimize the risk of sucking up water. That is not a foolish worry, either. Our New Guy at work had a Scion with a KN intake that he tried to drive through water that was deeper than he thought. The engine did not survive it.

Q: I have a suzuki bandit 1200 (2001) and I think it needs a valve adjustment. The engine is tapping at idle and while riding but I cant stop riding long enough to get it fixed. All the shops I checked with are booked for a week. Will I make the engine worst by riding it like this?: Motorcycle Valves

Q: the ac replacement valve seems to be leaking i was wondering what is the average cost of having it replaced..: The valve itself is only a couple dollars. Some shops have a tool that will let them replace a valve without dumping the charge but since its likely low you will likely also have to pay the regular AC service fee which is usually $50-100 plus parts and refrigerant.

Q: I have a 2004 yfz 450 and in the passed 4 rides (about 2 hours long each), one of my valves has stayed down and been broken when the piston came back up and made contact with it. After putting it back together the first time i checked numerous times to make sure timing, valve movement, and camshaft movement were all correct. and just 2 rides later (today) the same thing happened again. I have not began work on it yet so i do not know if it is the same valve. But has anyone ever had this problem before? Is this something frequent with yfz's or am i missing an important maintence issue? And can anyone tell me why this is happening? All help and tips are much appreciated!! Thanks!!: Commercially available assy lubes known effective include Microlon,, MPT,, SynLube Red grease,,, SuperLube High Temperature/Extreme Pressure Grease,, Your Choice should include some idea of how long you intend on keeping it,,how much you ride it,,,and how often you're willing to tear it down for valve stem inspection possible recoating. Titanium has some incredibly attractive properties,,,,and can offer Very Long Life.

Q: I bought the valve but i have been all over and nobody has a tube that matches mine they all say they have it in stock but once we get there they say it doesnt match. Even online i cant find one that matches. What do i do?: Can you give a little more info, like what is the year/model, and what is the tube you are speaking of? Are you looking for the heater hose?
