- Q:I recently converted my furnace from l.p. gas to natural gas. It's been maybe two weeks of me troubleshooting and replacing. I have a new gas valve and transformer in the furnace. There is 24v running to the valve and it clicks to open but no gas comes out. I have exhausted all my options with the mechanical/electrical components on the furnace. I have bled the valve to be sure that there was gas making it to the inlet side. Does anyone have an idea as to why the valve stopped opening once I converted it over?
- I realize this is probably a dumb question, but it has to be asked, just so everyone else won't have to wonder. Are you dead sure you put the valve on in the right direction? I'm not a certified furnace installer or repair person, so I don't actually know if it's even possible to put a valve on backwards, so, the question. It certainly sounds like you've done everything that could be done, other than to take the valve off and try getting it to open while it's off. If it's opening, it should do it on a bench, with 24 volts going to it. You may have to take the transformer with it to be sure, and actually look up in the holes to see if you can spot the flap opening up for the gas to flow. You haven't mentioned a pilot at all, so I have to wonder if this is an igniter type system? That would be my methodology of checking the valve and the transformer. If you can get it to open on the bench, then it certainly should open in place.
- Q:Is there a more technically correct name for a valve that slowly opens, allowing increased pressure in a water line without blowing the end off?
- I've always known them to be simply called motorized valves, but they aren't specifically made to prevent instantaneous pressure build up. They are usually installed as a convenience type of thing and in lieu of solenoid valve which WOULD be an almost immediate full pressure situation, but any valve other than a solenoid activated one will allow for slow build up of pressure. A motorized valve just lets you do it automatically and you don't have to be right at the valve location to open it. Al
- Q:I have a 1991 Toyota Supra turbo that has to have the valve stem seals replaced.It puffs white smoke upon start up,but it goes away.Just curious if the seals can be replaced while the head is still on the motor in the car.
- Yes, you can. There's an excellent article that gives you pretty thorough instructions on how to do that in the link below. Note: If this doesn't stop the smoking check and replace your Cam Position Sensor O-ring, that can cause this condition as well. Best of luck.
- Q:okay i have a 1990 plymouth laser. it runs very and the compression is good but it smokes. im thinking valve seals? Also i need to know the tool to remove the seals. Thanx
- spring compressor is only special tool you need, can borrow one at autozone for free (you pay a deposit but get it back) but one question, does it smoke when you start it up then quit after a while? that is valve seals. If it smokes after warm up and when you accellerate its probably the wiper rings in the engine.
- Q:My fiance needs his aortic valve replaced. He is 40 yrs old otherwise healthy. I am wondering how long he will be in surgery, how long he be in the hospital and any other info about having this surgery.
- where is it performed?
- Q:i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank
- The question is...where are you now going to get that filled providing the K valve actually fits the threads on that tank? Even if you bought a cheap alum 80 scuba tank...you'd still need to get that filled too. That valve would allow you to put a scuba regulator on it. You'd need to be scuba certified to be allowed to get it filled. Vicious circle, eh?
- Q:My fortuner stalls without warning, but restarts quickly, according to Toyota service center, we need to replace the suction valve, can someone please tell me how a suction valve work
- you need to be more specific. there are 100 things on a car that could be called a suction valve. Right off the top of my head the only valve that could do that is a EGR valve. If it gets stuck open the car will stall, but it will start back up after the valve closes again. The OBD will tell you if the EGR valve is bad, but other than that I can't say.
- Q:I have an 98 Mitsubishi Eclipse rs and its a little jerky while driving and i think it might be the PCV valve but I don't know where it is located.. where is it? and would this cause the check engine light to come on?
- Your okorder okorder , which covers all Eclipse/Talon models.
- Q:automotive cylinder heads and valve
- Valve rotators are just that, they cause the valves to rotate during operation preventing wear in only one spot there by extending the life of the valve and the valve seats.
- 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?
