Q: From searching around I feel that I need to replace this on my vehicle. Is the Suction Control Valve different from the Idle Control Valve? Sometimes at a stop light the engine will stall. A couple times it has happened while driving when coasting to a turn or stop.: hold the computer near the Pathfinder it will suck data directly off the internet (NO WAY) what you need is a complete diagnosis by a experenced Technician or a Nissan Technician. Idle control is on the bottom of the throttle chamber or on the intake manifold. Stalling and Dieing may be caused by a Distributor or air flow meter fuel pump or clogged up fuel filter. Suction control valve in not a part on your year pathfinder good lick

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?: Same thing happened to me, but with an oil boiler. Shut off power to water heater. Find the drain valve on bottom of unit, attach hose if it has a fitting. If you have an open sump pump in you basement, just drain into there, or you can fill buckets and keep emptying them. Use a pipe wrench to take of pressure relief valve. Take the valve to a good hardware store, or plumbing supply place so they can match it. Put teflon tape on threads of new valve (thats all i used, no leaks) and install then refill tank, you may have to manually hold down the water feed line. turn on power, and open all faucets to bleed out the air.

Q: whats the location of the pcv valve on on a 2001 bmw 740il (e38): In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.

Q: I don't know exactly what it is called...the water valve from the wall to the toilet is leaking. All of the parts need to be replaced. They appear old and corroded. Can you please tell me what these parts are called? About how much they cost? And is this difficult to do? I found an excellent video on youtube on how to replace..but just want to ask anyway if it's difficult..it doesn't LOOK difficult.: It's called a shut off valve, costs 6-7 dollars depending where you buy it. You will have to match the size of the valve to the size and type of the pipe coming out of the wall, could be copper or threaded steel pipe. Also replace the line from the valve to the toilet, this will have to be matched to the valve as well. Not a hard job but matching up all these things can be tricky if you don't know what you are looking at. Might be easier to get a handyman or plumber. If you do try it yourself do not forget to turn off the water - might have to turn the whole house off.

Q: what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?: There are 2 different ways, with the engine warm remove the valve cover start the engine and 1 at a time back the adjuster nut off till the lifter starts to click and tighten it 3/4 of a turn going 1/4 turn at a time this is very mussy with oil all over everything. The easiest way is to turn the engine to number 1 TDC and back off the adjusters till you can just turn the push rods with your fingers and then retighten 3/4 turn do this in the following order #1 E+ IN #2 - IN #3 E #4 - IN #5 - E--- then turn the engine 1 turn to number 6 TDC and adjust the remaining valves the same as the first in this order # 2 - E # 3 - IN #4 - E #5 - IN # 6 IN+ E Then reinstall the valve cover and your done much cleaner way

Q: sprinkler valve leaking: Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.

Q: I have to get a new vacuum switching valve for my 1987 toyota pickup. I was just wondering what it does, and if a broken one would cause my truck to not idle. It still runs fine when i drive it, but when i push the clutch in the RPM's get really low until it dies.: This valve probably is the EGR control valve - the computer monitors the EGR flow and controls the EGR valve opening by switching vacuum to it for opening or bleeding vacuum off for closing. If this valve fails to completely close the EGR valve at idle, the problem will mirror your symptoms

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: Hi guys, my parents had me install a new faucet in their kitchen sink. It works great and everything, but after the install the hot water pressure basically decreased greatly. The cold water pressure is fine, but I believe after I had turned off the hot water at the shutoff valve, something in the valve got messed up and is blocking the water supply.: Kitchen Sink Pics

Q: Can someone please explain the difference between a pressure tap valve and a gate valve (if any).: they have different functions, the pressure bypass valve is normally used in Heating systems, between the Flow and Return circuits, just in case all the radiators are shut and the water has no were to flow, some of the more sophisticated use a pressure differential between one side of the circuit to the other to operate, Also generally set at quite a low pressure. Pressure release valves are used on closed loop central heating systems or other water systems were unwanted pressure can build up, and usually will vent to some sort of outflow, IE over flow pipe or return to a hot water tank and operate at higher pressure and are more likely to be adjustable
