Q:how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
Q:I think the piece leaking is a valve;it is one solid piece of copper with two tubes, one which is a half inch that connectsinto the incoming hot water and then a small outgoing one that connects to the faucet and I don't know how to find a replacement part .. I think it is a Delta but I am not sure ... the house is 10 years old but where can I just find a valve instead of replacing the entire faucet if I don't know what the make or model is ?Any websites with pics of replacement valves for Roman Tubs??
Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.
Q:Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
Biological valve is made of human or animal tissue. These valves last 12 - 15 years, but you may not need to take blood thinners for life. Human body has a tendency to reject foreign material such as porcine valve. Medication can be used to retard this effect, but is not always successful. Biologic porcine heterograft - harvested aortic valve of pig that is preserved in glutaraldehyde and mounted on specially designed sewing ring. (Carpentier - Edwards/ Hancock/ Medtronic) Tissue valves are also made from 16 to 18 months old calves and harvested aortic valve from human cadaver.
Q:I've just been told that I need to replace the valve cover gasket on my 97 Volvo 850.....to the tune of $650.00 .....ouch.....is it that difficult to fix?......can you use the red gasket sealant? is there a difference between the head gasket and the valve cover gasket.......yeah I know there probably is.......but when I look on line all i can find is head gaskets......no valve cover gaskets........which scares me into thinking they are the same thing.....i'm hopeing i'm wrong......if its the valve cover gasket it looks like it would be right on top of the engine and fairly accessable.......or am I wrong......sure would like to save the $650 if it is something i can do myself!!!!
Valve Cover Gasket is a tuff thing to fix alone. I would say, take it to the shop and pay the $650.00- look at it like this, at least you will have a garentee if anything goes wrong you take that bad boy back and have them hook it up the right way! Best of Luck!
Q:according to my study only indurial gate valves have both rising and non rising stem through handwheel and it seems that it doesnot apply to golbe valve and globe valves are only non rising stem. i wanted to know if this is right
The valve in the upper left quadrant of the picture on this web page is a rising stem globe valve. This type of globe valve is common in cast steel and forged steel valves like those used in the oil and gas industry. They can be as small as 3/4 up to about 8 sizes.
Q:why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?
Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.
Q:ok so the water main that comes into the basement the valve handle snapped off so how do i shut the water off so i can replace that valve? I called the water company and they said they cant shut off the supply to the house because it is private property and we have to call a plumber if so how can they shut the water off and on if we dont pay the bill?
Broken Water Valve
Q:Around the relief valve there is water leaking it is not the valve it's self or the threads it's around the out side of it. The valve is on top of the heater
Hi, Unless the valve released isn't seating properly then you're better off to just replace it, maybe it's stuck thats where pressure is being released?
Q:I have just been diagnosed with a Mitral Valve disorder. The Doc's notes say Trace Center Regurgitation. Also Trivial Tricuspid Regurgitation. In simple terms, what do these things mean, what causes it, and how do you treat it?
This means the valves in the heart have a little leakage, so rather than produce complete forward flow there is some reverse flow (regurgitated). To determine how much of a problem this presents to you, find out what your ejection fraction is measured as, anything over 50% is good. Ask your doctor to explain, and put this into prospective for you.
Q:Hi i have a 00 bmw 320d and am trying to find out information on puting a dump valve in, is it possible?, what type of dump valve? and how hard it would be to put in?? any help would be much appreciated.....Thanks!!
