Q: I opened the OPD valve on the BBQ propane tank and propane spray out, I have heard that propane should come out only when it is hooked. Is there something wrong with the propane tank?: The okorder /... I hope this helps!

Q: I am going to replace the EGR valve on my 99 Pontiac GP with the 3.8. It needs replacing(has already been cleaned twice) and keeps popping the code for it. Anyways..my question is: after its replaced what do I need to do to reset the codes or computer? Someone told me to unhook the battery for a hour and that will do it???? Is this true? Any help out there?? THANKS!!!!!!!!!!!!!!!!!!!!: a great type of the time its not the EGR Valve, this something else. Do you no what code or codes have been discovered ? i've got seen the O-ring lacking on the percentvalve alot and this journeys a EGR code, verify the percentValve for the O-jewelry or while the engines ruining open the oil cap and verify to verify if theres a great vacuum there. if so the O-ring is lacking.

Q: I just found out about my condition. Is it dangerous? And will I need surgery? My mom just got her monocuspid valve replaced. I don't wanna have to go through the same thing. And will I still be able to go on rollercoasters? I'm going to cedar point tomorrow. I only want answers from people who know exactly what there talking about thanks: Yes you might have constantly had this, it is some thing you had been born with. A natural aortic valve is tricuspid, that's it has 3 final flaps, however a bicuspid valve best has 2 flaps. Sometimes those bicuspid valves provide no issues, however in a few individuals they are able to result in center murmur later in lifestyles ( mostly on your 30s or 40s ) in view that they enable somewhat blood to leak again the flawed manner while they're closed. If this will get extreme sufficient, you can also want surgical procedure to suit a man-made valve. This is lovely ordinary at the moment and now not some thing to fear approximately.

Q: Hi,I have a 2002 Honda Accord with 115k miles which recently gave a ECL. The Honda dealer identified this a P1457 and says that the EVAP bypass solenoid valve needs to be replaced1) is this referring to this valve?: DTC okorder Otherwise: Don't forget to close the question. Thank you.

Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?: Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.

Q: Hey there in new england wth a blizzard on the way :(. I noticed a few weeks ago that my radiator in my bedroom was always cold. I have lived in this house for 11 years don't know why I am just noticing now. Anyway I discovered that the radiator valve in my room was closed. I shoudl have know it was closed for a reason. I turned it on Wednesday night. everything was fine until this morning. It started leaking thru the celing. my husband tightened it turned it back off and it was fine for a while until it started leaking again! I have since turned the heat off. What can I do now? Did I mention we are bunkered down for a blizzard here? I won't get a plumber out here for days and I fear with the blizzard winds if I keep the heat off the pipes will freeze! Help any suggestions? why didn't it stop leaking after we turned the valve off again??? I am so freaking out right now!: daniel treasure was correct, but if it is still leaking then it is the packing gland that has worn. make sure that both rad valves are closed, keep hold of the spindle on the leaking rad valve with a appropiate tool so it does not turn, then loosen the packing nut clear of the valve so it rides up the spindle, where the packing nut left the valve you will see the threads where it was attached to, now, get some fine string and a small eletrical screwdriver/ pointed knife, with the string wrap it round the spindle and push into the packing nut theads, but leave some threads showing so you can get the packing gland nut start to bite, tighten the nut up, open the valve slowly and hopefully the string will have compressed enough to stem the leak. good luck.

Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles: in case you have a broken valve, the broken element will probably destroy the cylinder and piston in case you run it that way. ought to easily be a flaw in the unique valve or another ingredient, no longer person-friendly to appreciate.

Q: had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning: freeze the line coming to the valve, with a co2 fire extinguisher, or dry ice, then swap the valve, and let it thaw

Q: will a blow off valve work with out an intercooler???(civic 2000)and also, is a blow off valve a turbo?whats the diffrence between a turbo and a blow off valve?? thankss..: A blow off or pop off valve controls the boost or pressure the turbo or supercharger is pushing into the engine.A turbo makes the boost.The blow off valve controls it so you wont run too much boost or pressure into your engine and leave pieces of it all over the street.The blow off valve can be adjusted to control the boost,6- 8 lbs.should be sufficient for a street application.The blow off valve simply allows the excess pressure built up in the turbo to be vented or blown off so it wont be forced into the engine.The boost on a supercharged or blower application is controlled by swapping the blower pulley to either underdrive the blower or overdrive the blower,depending on which way you want to go.

Q: I have a intake valve leakage in both my car and truck. If there some sort of quick fix i could use to stop the leakage for about 1 month.: what is leaking in to where? assuming that your talking about the intake and exhaust valves,then here goes. if the car and truck are old enough to have a carb on them then if you have gas leaking past the valves then you will need to clean the intake valves, if it's oil leaking into the cylinder then you will need to change out the valve seals-those are located under the valve springs. to do that job you will need an air compressor.if it's compression blowing past the exhaust valves then you will need to pull the heads and have them serviced, same with intake cleaning. sorry no quick fix. either fixed or malfunctioning,those are the choices
