Q:Are all the valve games tied together?
there are lots of possibilities. in left 4 dead Ellis once said he played team fortress 2 and Louis has played half-life. plus in portal there are several references to black mesa which was in the first half-life, also in half-life episode 2 you see an aperture science ship called the Borealis which hints at what happened in the time of portal 2. so in turn there are plenty of connections of between the valve universe's but no actual crossover has actually happened. but a big connection between two games i cant quite figure out. in left 4 dead 2 at the dark carnival you can win a garden gnome in a shooting gallery, if you can get the gnome all the way to the end of the level you win an achievement. but strangely in half-life episode 2 you can find a garden gnome at the beginning of the game and get it all the way to the base where you can stick inside a rocket where later you can blast it off into space! whats strange about this is there no clear connection between half-life 2 episode 2 and left 4 dead 2, since its already established that half-life is a video game in the left 4 dead universe. i mean in fiction most crossovers involve some kind of dimensional rift or tare, or even a portal...wait a second.
Q:Cost to replace/fix valves?
To replace valves would probably run around $500. Plus they will probably charge you about 8-10 hours in labor to remove/reinstall the head from the block at about $90-$100 an hour. Not to mention the replacement of gaskets which could be around $100-150 So it can get pricey. I would budget for about a $1750-$2000 worst case to have this fixed. I am sure this isn't what you want to hear but once you start getting into the internals of the engine, things are going to get pricey.
Q:Standing water under sprinkler valves?
Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
Q:Leaking Proportioning Valve?
Q:removeing the driver side valve cover?
Really? I find that innane. rocker covers usually come off pretty easy, and are well above the manifold-unless its a sidevalve???
Q:Are OHC valves generally smaller than pushrod valves?
Depends on the displacement of the engine and the size of the valves use, generally speaking four valves will cover more surface area than two valves. Using larger valves is generally cheap than using multiple smaller valves and less mechanically complex as well. But larger valves often need to be stronger and stiffer valve springs are needed, stiffer/larger valve springs = more energy required to open the valves which means there's a loss of power there, you can get around this somewhat by using stronger yet light materials like titanium, but if you do that, it can get expensive. And there's also the option of using multi-valve heads on pushrod engines like you see in the diesels used by the big three. To answer your question, there's no hard and fast rule about it.
Q:where is the location of the iac valve, 97 galant?
The idle air control valve can be found under the throttle body. In order to get to it: 1. Disconnect negative battery cable. 2. Remove air intake from throttle body. 3. Disconnect throttle body cable. 4. Disconnect sensor connectors from IAC valve, and throttle position sensor. 5. Remove 4 bolts from throttle body using 10mm socket wrench. 6. Take throttle body, turn bottom side up, remove 4 mounting screws from IAC Once you do that you have removed the IAC. Reverse the steps to put it back on starting at number 6 and working your way back to number one How do you replace an air idle control valve? Replacing an idle control valve can be a daunting task. For your specific application, we recommend to ask in our car forum for advice. Here we will describe the basic process for replacing your idle control valve. Please note that for different cars and trucks the process will not be the same. Steps to replace your idle control valve You will want to begin by first gaining access to the idle control valve. In order to do this you will need to remove the air filter assembly, along with the air mass sensor and the air mass meter boot. Once you remove this whole assembly, you should have easy access to the throttle body. Remove the four bolts that secure the throttle body to the intake manifold. Usually on the bottom of the throttle body, on fuel injected cars, there is a idle control valve. To remove the old valve, simply unscrew or unbolt it. Bolt on the new valve, and reinstall everything. Make sure you replace your throttle body gasket at this time.
