Q: How do you clean an EGR valve on a 1999 Ford Taurus DOHC? What do I do and what can I use? Will water work? I've read a lot about a plunger mechanism but I have no idea what this is. Please explain in the best detail you can how to remove, clean, and re install the EGR valve?
You will have to use an appropriate size ratchet wrench set. The valve is held in place by 2 bolts, usually. It is round and flat, and has a diaphragm inside the metal cannister. Once you have removed it, invert it. It will be full of unburned carbon which is easily removed with spray Gum-out and a small brush. If you are unlucky, and the internal diaphragm has broken, you will need to replace the valve. This is pretty rare, though. EGR stand for exhaust gas recirculation. This is what the thingy does. Under acceleration, vacuum from the engine causes the valve to open and scavange exhaust gas from the attaching pipe. Usually, and I should not write this, I just plug the vacuum on these things to prevent them from opening at all. Then I install a set of Bosch Platinum, Fusion or nippondenso Twin Tip plugs. This will reduce pollution, anyway, which is the goal of having an EGR valve. WHen it is diconnected, no carbon will get sucked back into the intake system, and the engine will stay cleaner inside. If you are smart, you will begin using Mobil One 0W-30 oil. This will improve your gas mileage, keep the inside of your engine cleaner, and you will only need to change it once every year or so. This oil will help prevent the formation of unwanted sludge and carbon deposits. You will be amazed at how much gasoline you end up saving!!!
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
Q: I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?
It all depends upon the wear in the cylinders of the engine. Usually they are honed and made smooth again prior to installing the new rings, seals, etc.
Q: We have a wall mounted shower head as well as a ceiling mounted shower head. Suddenly the turning valve for the wall mounted head does not work, only the ceiling one does. Is this stripped. Can it be repaired with a marble wall? I have a photo if needed. Thank you ahead of time. Patrick
The mixing valve is in the handle that turns the water on. You don't need to take down the wall to get at it. The handle come off including any cover plate and the valve is right behind it. Be careful not drop/lose any screws or washers. They are small. The home center sells replacements for certain brands so get that information.
Q: So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
Well some what true an egr mifht create a vacuum leak making the engine run faster but to burn a piston it woul have to be close to the cyl like a intake leak easy way to check for vacuum leaks is to take a can of carb clean and spray down the intake and listen for idle change (don't spray dist)
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 !
They are two different burners, with different ignition characteristics, and CANNOT be used for both gases. Get the correct one for your use.Simple. Safety first! Done.
Q: I noticed when I pulled my pcv valve off the valve cover the entire guts were missing. what would this make the car run like?
It would just make a bunch of oil pool up in the intake. If it was plugged it could damage seals.
Q: can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
