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

A gate valve is used as a shut-off, not a regulator. It is supposed to be either all on or all off, and the handle only has a total movement of 90 degrees. When the handle is aligned with the pipe, it's on, and when the handle is perpendicular to the pipe it's off. If the handle is turning more than that, it's broke and needs to be fixed or replaced.

Q:How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/

I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

Q:When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?

Intake valve will line up with the intake port from the intake manifold and the exhaust valve will line up with the exhaust port going to the exhaust manifold or header....intake is usually larger of the two.

Q:What are better valve cover gaskets for a car? Cork kind? Or the rubber kind? Or either rubber/cork kind?

For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good

Q:Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine

you will need to remove the plugs, get a air compressor with a hose that will screw into the spark plug hole ! then you pump the compressor up to about 40 or 50 pounds, take the rockers off and pull the push rods ! you will need a spring compressor to squeeze the valve spring and take a pair of need nose pliers and take the keepers out and then the spring will lift off the valve stem ! after the spring is off you can remove the valve seal ! i recommend for you to use the umbrella type seals !

Q:i have an 87' monte carlo ss, 64K on 305 w/ cam, headers, roller rockers and springs. ive been seeing blue smoke out of my exhaust ALOT during start up, but it also continues to smoke at idle, i've been told it's a good chance i need my valve seals replaced and was wondering what the general ballpark was assuming there was no other complications in the process of replacing these?

Hate to say this but Chevrolet never put *valve seals on top of the valve guides in a stock OEM engine. Standard Chevy engines depended upon the umbrella shield that fits around the top of the valve springs held in place by the spring retainers and valve split locks as shields to keep splashing pushrod oil off the valve stems. Any time you have smoke at start-up and at idol you have worn or struck rings in the piston ring grooves or mis-shapen cylinder walls. Typical valve guide wear delevers blue smoke put the tail pipes on *deceleration when vacuum pulls oil down the increased clearance between the valve stems and the honed valve guide holes.

Q:problem seems like a bad IAC valve - When I start it, it runs at 2000 for 10 sec then starts varying between 1000 2000 rpm at idle. Over 2400 it is level. If I pull the connector it will vary quickly around 1500 rpm as soon as it is started. Cold or hot no difference. 10 sec delay will happen every time it is started.I just replaced the air cleaner and cleaned the PCV valve, which seems to work about the same as a new one, then this started. Coincidence or something else wrong - like an air leak? How can I be sure it is the IAC??I've pulled the air intake and plugged the bottom throttle port and it goes to idle. the only trouble code is 0505 unless of course I pull the connector. Pulling the throttle position sensor plug yields a constant 2000 rpm and an code indicating it is open.thanks.

yup sounds like the iac valve,or quite possible that your low on coolant,it requires coolant as a media to transmit signal to ecu,coolant also runs through the valve,check coolant first,they tend to leak at the bypass gasket between cyl head,the housing behind where egr mounts,good luck

Q:Ok i dont know much about cars so if anybody could help out with this id appreciate it. Do i need to take my car in to get the PCV valve replaced or can i buy it and have it done in my driveway?Thanks....

most cars the pcv valve is easily replaced it is usually on the valve cover if you can see it you should be able to replace it if you cant see it it may be burried in the engine somewhere pcv stands for possative crankcase ventilation it keeps the pressure out of the crank case.(thats were the oil is circulated0

Q:I acquired an old valve guitar amp not long ago and i think it needs new valves trouble is the valves that are in it have no writing left on them and there is one valve completely missing how can i find out what type of valves to put in it. Could i use a multi meter to see what voltage etc is going into the valve socket and then find a valve with matching voltage. Thanks for your help Marc

I never considered VOX a crunchy amp, has more of a jangle sound to me. Not sure what wattage you are looking for. In my opinion you don't need many watts in a class A tube amp. I heard an Orange Tiny Terror through a Marshall cabinet recently and it was awesome. I am considering that head with the Orange 2 x 12 cabinet. That head is only 15 watts but man is it loud...and crunchy.

Q:Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!
