Q:I want to change a stuck pcv valve on my 86 toyota pickup 22RE. I've used tons of lube and picked away at the grommet but i still can't get it out. Any advice?: the grommet is being replaced so do what you have to to get the valve out. id grab a hold with a pair of pliers and go that route.

Q:i have a 8v fiat punto...is it much work to add 2 valves to make it a 16v?: Ha...ha...ha

Q:I have an old trumpet valve stem that will not screw in the valve cap. I ordered a new one but I'm not sure how to remove the old one and put the new one on without doing anything that would influence the look and playing. HELP!!! Professionals are welcome and others. I don't have any professional technicians near by .Summer band is starting up so I need this FAST.: I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.

Q:What are the requirements for valve automation?: Valves are commonly available for both liquid and gas. You would begin by determining operating pressure, volume, nature of fluid, and temperature of fluid. The electrical requirements are as simple as supplying power to a solenoid. Mechanically, automatic valves are sophisticated. Begin by researching the water supply valves for a domestic washing machine.

Q:Where is the illusive heater control valve?: The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......

Q:I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help: Yes you can drive the vehicle with 1 broken bolt to the valve cover. The valve cover should leak a little due to the lack of tension at the broken bolt. The leak may be minimal. If you remove the valve cover use silicone as a new gasket, you can use extra silicone at the broken bolt. Allow the silicone to dry before tightening the valve cover bolts. The extra silicone may stop any oil to blow by the broken bolt problem solved. The valve cover does nothing more than stopping oil from leaking. A leaky valve cover nothing more than leak will not affect how the vehicle runs. The cost to have the broken bolt replaced should be around $100.00 (if the broken bolt is accessible) The cost is strictly labor (time). About $100.00/an hour. To repair this you have 3 options; 1) You can extract the bolt. This may be very easy depending on the accessibility (can you get a drill over the broken bolt?). If you can drill a whole in the broken bolt, you can lightly tap an extractor into the whole with a hammer. Then with a wrench or a pipe wrench you can try to extract the bolt by turning the extractor counter clockwise. Use WD40 or a catalyst to loosen the broken bolt. The longer the catalyst (WD40) has to work the better. ie- spray the broken bolt 3 or 4 times a day allow the oil time to loosen the broken bolt. You can purchase extractors at any auto parts store for about $15.00 I can't emphasize the importance of WD40 enough!!!! 2) The 2nd option is to use a healy coil. You would need to drill out the bolt to a specific size (the healy coil package will tell you what size drill bit to use). After drilling out the bolt you can insert a healy coil that will allow you to use the same size bolt you just drilled out. The healy coil package will have detailed instructions. This is very easy to do! Healy coils can hold a lot more torque than valve covers require. 3) The third option is to drill out the broken bolt completely tap new threads insert a larger bolt.

Q:Kenmore washer ,cold water trickles in, pressure from faucet OK. Must entire valve be replaced?: 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:what is a silicone purge valve.: There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.

Q:I was told my 1995 chevy needs an idle air control valve. I know my idle is getting rougher so I may need this. What is the function of this valve and what would happen if I don't get it? Will a new valve smooth my idle? Anyone know if this valve is hard to install or not?: The IAC (Idle Air Control Valve) controls the amount of air getting into the throttle body/intake to coincide with the correct amount of fuel to get the perfect fuel/air mixture for proper combustion. Too much or too little air will affect the performance of the engine at idle. If you have the 5.7 350 v8 the idle air control valve is really an easy fix. it sits right in the throttle body and is easy to get to. Autozone in Houston, TX has them for about $22... If you don't get it your idle will be poor and the engine could possible stall at idle.
