Q:How much for a valve job 96 Camry???
The devil is indoors the extra advantageous factors. Is the motorized automobile indoors making use of variety the area you should look into. what variety homeowners. Any maintenance records. Is the unique distributors instruction manual secure. i'm going to have a Toyota mechanic placed it on a advance and look into under heavily. There are rubber boots that carry particular lubricants mandatory to the drivetrain that have a bent to crack and leak with age. Has the Air Cond plumbing been switched out to settle for the nice and comfortable variety refridegerant. Do the belts and hoses look right maintained? My advice is to bypass forward and stumble on extra present day variety with fewer miles. Older autos, even Toyotas with that many miles that have not been right maintained can develop right into a funds pit and pass away you stranded. making an investment extra funds now can advise saving multiple funds and subject indoors the destiny.
Q:Sprinkler Valves?
If it is $50-$70 installed, that is a good price. Where I work, we get $125, and that is about the going rate in the north east. If you want to do it yourself, do not use Toro valves, Toro is garbage. Hunter, Rainbird, Irritrol, and Weathermatic are all good valves. Dig a nice big hole where the valves are, longer on the downstream side of the sprinklers. Cut the line coming out of the valve, and unscrew it. If it is a tight fit, take the valve apart and unscrew it. If you have to take the new valve apart to put it on, There are only 3 parts inside, so don't worry about not being able to put it back together. From top to bottom, they are the spring, the rubber diaphram and the plastic ring. Then reconnect the lines coming out of the valve. Then connect the wires from the solenoid. 1 wire from each valve gets connected to the common wire. Look in your timer to see what color it is. Then the other wire gets connected to individual wires. Check the order of the wires to the valves. Write it down. This will help keep the valves in the same order they are in now. The prices you got 50-70 is what your gardener told you for each (i am assuming that he is installing them.) The 300-1000 just estimates for installation from different contractors. Unless you have 8 valves or more, the $1000 sound real high. You do not have to be a plumber to install the valves.
Q:what does a Pneumatic valve do in a process?
pneumatic valves use pressurized gas (Air, nitrogen) to operate.A simple example if you are monitoring the level of a vessel in a process the indicator for level (LI) tells you remotely what the level is. If you need to keep the level stable the level indicating controller (LIC) sends a signal to the regulator on the Pneumatic Valve which provides air to open or close the valve depending on what the vessel level set point is. the FIC (flow indicating controller) PIC (pressure) TIC (tempurature) are all instrumentation used to compare a set point parameter against a measured process variable and send a signal to control the valve to maintain the set point
Q:Clogged EGR regulator valve?
The thing you did not say was if you had any codes. If the valve was stuck and that would have to be in the open position you would have codes for the O2 and the EGR. And that includes the answer from Cleonitro. Your more likely to have dirty throttle body butter fly's and a dirty air by pass or MAF sensor which ever your vehicle has.
Q:sprinkler valve leaking water?
I have been given the equivalent line from our water application whilst the stress valve broke and blew up our water softener it rather is the 1st element on the line from their tension regulator. luckily, it has a life-time insurance yet their plumber instructed me that it extremely was once the accountability city on the grounds that of the stress regulator which they admitted to being at fault whilst they replaced it.
Q:any way to treat aortic stenosis besides valve replacement surgery?
Despite what Carly has said valvuloplasty is always an option but you have not offered much information to work with. Calcification of the aortic valve is not synonymous with stenosis of the aortic valve. There is no way to reduce calcification of the aortic valve leaflets. If there is aortic stenosis this places a strain upon the left ventricle. The most common approach is to replace the aortic valve prior to permanent harm being done to the left ventricle. It would be helpful to know what the findings of your echocardiogram and most especially the pressure gradient across the aortic valve and the left ventricular ejection fraction. If I may be of further assistance please let me know. I wish you the very best of health and in all things may God bless.
Q:Can faulty valves cause high oil consumption?
I'm guessing the motor was running some blue smoke out the exhaust especially at start up. And I'm guessing it was probably a combination of rings and valves. She's twenty years old. Worn rings allow oil to escape into the combustion chamber from the underside of the piston and worn valve guides/seals allow oil to be burnt away from the top. When the guides/seals become worn or dry from age they allow the oil to leak down the valve stem. That's why you will notice them being worn especially at start up. While the bike sits it gives the oil a chance to pool at the edge of the valve to head surface so when the valve is first opened a accumulated amount of oil to enter the cumbustion chamber.
Q:Hoe do you install a sprinkler valve?
Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.
Q:1981 xs650 yamaha valves?
Remove both spark plugs. Remove all 4 valve inspection covers. Remove the Generator cover (L crankcase cover, round, 2 screws). It doesn't matter which side you start on. Turn the crankshaft in the direction the engine runs. Depending on which cylinder you're working on, watch that intake valve. When the rocker arm pushes it down, then comes back up, the piston is then moving up on the compression stroke. Continue turning until the piston is at top dead center. You can line up the T mark on the flywheel with the pointer, or look into the spark plug hole to see when the piston is at the top. Adjust the valve clearance for the intake exhaust valves on that cylinder. Repeat for the 2nd cylinder.
Q:aftermarket blow off valve info?
Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.
