- Q: Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks
- valves dont knock they tap and generally all you have to do is adjust the valve lash, but you may need new valve springs if those heads have alot of miles or were abused.
- Q: where is the oil pressure relief valve at in a 2003 ford focus
- Oil Pressure Relief Valve
- Q: Slow songs are a major factor of this this lagging sound. Note to Note. I Oil my Valves often and they still are slow. Am I just not using enough air? Help me Experts!
- I am wondering on the make of your instrument. I have gone from a Yamaha euphonium to a Bach and now to a Yamaha pro model Baritone ,compensating 4 valve ( English bore) Having been previously a professional trumpet player I really did not like the long valve stroke on either of the euphoniums. The baritone has great valves albeit trickier on intonation.
- Q: Water is seeping up around relief valve threads. Tried tightening but could not get it any tighter.
- Donald; Don't try to tighten it, or replace it, it will fail. Lower the thermostat to no more than 120F degrees, and start shopping for a new water heater.
- Q: My valve cover gasket has less them 2k miles on it and i noticed in some areas there is a lil oil shine around it so i was thinkin maybe i have to retighten the valve cover a lil bit more?
- Not unusuall, just snug them, tho - Don't smash the gasket.
- Q: I've been working on cars since around march of 2012. I new. I have a set of 305 heads that were really dirty. It came from a 79 camaro that never had an Oil change. I took the valves out and the valves are pretty burnt. I was wondering If I cleaned them up would they still be good to use? The edges aren't rough or anything. Just let me know what is need to know please. The heads I know are still good.
- People reuse valves all the time, just need to inspect them for straightness, keep them in the same locations in the heads and relapping them is a great idea also.
- 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.

- Q: my Hunter SVC VALVE will not work with my Lawn Genie Valve. Is this becaous the voltage is not matched? Hunter says it operates solenoids at 6-9 v DC // Lawn Genie says it is an 18 v DC solenoid. :-( my original Hunter Valve broke and I replaced it with the Lawn Genie. Should I get a Hunter Valve , or a Lawn Genie Controller at this point/ or is there something I have overlooked?.
- Something is incorrect. All valve solenoids and all timers are designed to work at 24 v DC It should make no difference which brand of clock or which brand of valve you are using. Now the actual solenoid which is the circular cylinder with the wires coming out of it that screws into the valve may not fit all brands of valves but you can buy the correct brand to fit your valve at any irrigation supplier. If your controller is working with at least one valve it should work with any valve you have installed. I would look at the wiring and see that they are correctly installed and connected especially at the valve. If one of the two wires is loose or connected wrong then you wont get the valve to operate. If you have a voltage meter I would test it with that. If not make sure at least one wire from each valve is connected to the white (or nuetral wire) out of the controller and the other valve wire is connected to one of the hot wires coming out of the controller. If one valve does not work try connecting a hot wire off a working valve to the non working valve and test it. If it works your problem is in the wire you disconnected. I constantly work on sprinkler systems and wiring is no. one problem. Incidently I cant find a SVC valve listed in the Hunter catalog did you get the letters mixed up?
