Q:Amount of gas lost through relief valve?
Below is one of many sites with software for sizing relief valves. Each relief valve has a specific orifice size usually indicated by a letter such as A, B, C etc. With this and the other information on the gas being relieved you can calculate the rate the valve is relieving when it is open. Note: most of the time you will be in the critical flow range so once the valve is open the flow rate will be constant until the pressure falls and the valve reseats.
Q:valve mismatch?
Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
Q:missing my pcv valve?
Will run at higher idle and suck all the oil out of engine, then run bad until engine locks up and exhaust would be smoking like crazy. plus other things. Suggest you replace and check oil level.
Q:How do I shut off a leaky hot water valve?
In some homes where the sink is mounted to the wall, as in your case, there may be shut off valves in the basement directly under the bathroom. If there are none there then you will most likely need to shut off the main water the open the bath room sink faucets to drain off excess water. Good luck.
Q:Kenmore washer inlet valve?
see if you can find a manuel on it also try tracing the wires that go to the valve and back track from there. there is also water level switches and tempture switches that might be messed up
Q:Sound when I open or close rain bird sprinkler valve?
It could be the solenoid. It could be actuating very slowly and hammering when it tries to shut off. The solenoids are only $5 or $6. Not a significant expense. I just had to replace an entire valve. Not costly but a good size hole while I was working on it.
Q:Question about gas valve on grill?
To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.
Q:bent valve stem?
I'd say the timing chain either broke or the cam gear is worn off,cam gears used to be made of fiber rather than steel on older engines. When the cam stops turning the valves stop working and when the piston comes up it then hits any valves that are open bending the valve or push rod or both. If this particular engine is run by a belt and the belt breaks you get the same result. To check this you can take the timing cover loose on the front of the engine and check the condition of the chain and gear.
Q:Electric supercharger. Blow off valves?
Hey guy. First off, you shouldn't even bother putting in an electric supercharger. The reasons are the about of boost you are going to need to see any REAL advantages you will not get from an elec. I suggest do what I am doing and spending the money to get a GOOD valve job and get everything polished to match and you will actually gain H.P. I have seen 32 hp gains out of a 2.2 I4 F2 engine from a probe by just adding a cold air intake, going to a 2 inch exhaust w/ header and a good valve job. Incidently, I now run 142 hp instead of the original 110.
