- Q:Its a 1981 Monte Carlo SS with a GM 350 crate motor. There is oil all over the heads valve covers. It isn't my car, but I was thinking of buying it..Thank you.
- It needs a new valve cover gasket which is cheap and easy to replace. Gaskets dry up and break from heat and age. Then all that sloshing oil underneath gets out. Loose valve cover bolts can also be a problem. And the valve cover may have been damaged by someone over-tightening the bolts. This thing is a 100 in human years. What happened to the valve cover gasket (rot from heat and age) is just one example of what has probably happened to many things on it - other gaskets, seals, hoses, tires and belts. Have seller prove he did a timing belt change when needed. It needed that at about 100k or 11 years ago. If seller can prove it, then guess what? It now needs another timing belt.
- Q:In the very near future I'm having valve replacement surgery. I haven't yet been told the risks or the recovery period, does anyone know the risks or the recovery stages and how long recovery takes?
- Valve replacements actually have very low morality rates like 1-2%. There are always risk's with surgery though, such as blood clots or irregular heart rate. The recovery in the hospital is generally 5-7 days, and then it can take anywhere from 8 weeks to a year to feel recovered.
- 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:My 4.0 L V6 2002 Ford Explorer has this plastic casing on top of the intake manifold...some of the hoses (brake booster, etc) are actually connected to the plastic casing, now how can i replace my pcv valve?
- The PCV Valve is not connected to your brake booster. If it were, engine oil and other debris would be pulled into the booster diaphragm and contaminate it and destroy it. Your PCV Valve is located on one of your Valve Covers. The Valve Covers are the long metal lids that run the full length of your engine on either side. Normally your oil cap is also located on one of the covers so you can fill your engine with oil when needed. The part that you are looking for is normally made of plastic or metal, and it is seated in a rubber grommet in one of the valve covers. You will normally find a single rubber hose coming from it leading to either your air cleaner or a port on the intake plumbing. Normally located before the throttle body. The PCV Valve itself, is a cylindrical object that is normally about 1/2 inch to 3/4 inch round and about an inch to 1.5 inches tall with a single, (sometimes double) port at the top. There is an object on your intake manifold, and sometimes also located below your throttle body, that does look like a PVC Valve. But its not. Its a simple vacuum port connector for access to manifold vacuum to operate things like your brake booster, and some of the emission control devices. I hope that helps you out. Good Luck!
- Q:I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.
- It does actually no longer something stable on your motor vehicle except you push 20 lbs of advance. it is going to truly make you run wealthy between shifts and could additionally provide you idle issues. our first improvements could be suspension. the vehicle handles properly inventory so getting better it will make the vehicle fell extraordinary. i'm assuming you're new to turbocharged automobiles so i might advise analyzing up on sites like I-club or NASIOC and learn as much as you may in the previous you initiate enhancing and blow your motor. It happens each and all the time so i'm no longer exaggerating.
- Q:im 28yrs old with two babies.in my heart two valves are very tight and leaking too,im going for a transplanting them in august.If there is anybody who got this problem solved please share.Thanks in advance.
- Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
- Q:What exactly is a flow valve for an ice maker on a refrigerator? Any idea what it would cost to replace it? Is it easy to replace?
- sophisticated situation. look on to yahoo. just that can assist!
- Q:i bought thie air connector kit and it has y-valves, suction cups and air control valves, what are the air control valves for?
- The air control valves are to control air flow rate going to the filter/device in the tank.
- Q:Hi everybody,I need some information about the operation of a double solenoid valve and how to control it using a PLC
- A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work in the direction is was working in. Again, depending upon what the cylinder was doing, this may or may not be desired. For Conrolling with PLC you may need to wire two discrete outputs of PLC to those two solenoids using relay. And the ON/OFF those two outputs as required.
- 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?
