- Q:I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.
- The single valve is the master control valve. It shuts the system down at the end of the irrigation cycle. It's a safety element in case one of the zone valves doesn't close or close completely. The other valves are probably digitally addressable. Your timer opens the master control valve and then digitally selects each zone valve in turn and waters according to a programmed cycle. These systems are called irrigation sequencers. Some of them are wireless.
- Q:The tricuspid valve is closed: a. during the rapid filling of the ventriclesb. when the mitral valve is openc. during ejection of blood from the ventriclesHelp plzThank you!
- The tricuspid valve is the connection between the right atrium and the right ventricle, so when blood is rapidly flowing from the RA to the RV, the tricuspid must be open, so it's not A. The tricuspid and the mitral valve open simultaneously so it's not B. As the RV contracts to eject the blood from its chamber to the pulmonary artery, the pressure created within the chamber closes the tricuspid valve to prevent the blood from flowing back to the R Atrium, so the answer is C.
- Q:I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- you are going to not like this first drain coolant 2 remove the throttle body linkage remove the pipe going to the egr to exhaust manifold [helps to use penatrating oil] remove assorted hoses to get to removing the upper intake plendeum {not the lower intake] [you need to put a shop towel over the open intake ports at the engine to keep any and all debries out of the intake ports to the engine] you should be able to see the valve covers by now remove the valve covers bolts remove the valve cover clean the gasket surfaces on the cylinder head [don,t leave ant debries in this area or in the valve cover [cleanlyness is a really good thing at this point in the build keep the crud out] there are some half moon seals that need to be replaced at this time located on the ends of each cylinderhead put a light bead of RTV high heat silicone on the rounded side of the seals and install the seals in thier half moon bores the RTV high heat silicone will kinda squish out of the seal don,t let the beead get carried away wipe of the sealent with a clean towel [shopcloth] not paper towels put a little RTV high heat silicone across the seal s flat side wipe flat with your finger install the valve cover gaskets on the valvecover [a little automotive contact cement for weaterstripping helps hold the gaskets reinstall everything fill coolant system change the oil and filter look for leaks a book or parts guy should be able to help find the right touque to tighten the bolts remember cleanlyness works here good luck should take about 8 to 10 hours note do not reuse any gaskets any where new hoses would not be a bad idea along with a thermostat ihawk3
- Q:have a 86 flhtc had new cylinders 10-1 pistons supposed to be 86 cubic inches when i run it up to 90-95 bending valves what can i do to stop bending valves-------HARLEY DAVIDSON
- I'm leaning toward the valve float or lifters pumping up idea. I wouldn't double up the head gaskets because you're asking for a leak, especially with your high compression. A good way to determine how much actual clearance you have between the piston and valve is to stick some soft modeling clay on top of the piston where the valves are, torque down the head, turn the engine over and take it apart. You will then be able to measure how thin the clay was flattened out to, giving you an idea of the clearance. If you seem to have plenty of clearance, then it may be valve float. If you've swapped out the cam, also compare the timing as well as the lift. The actual lift may not be a problem, but if it's opening sooner or later than stock, that may be when the valve and piston collide.
- Q:I have a 2000 Mitsubishi Eclipse GT.I just replaced the EGR Valve yesterday, and disconnected the battery to reset the code.My old valve was nasty and loaded with carbon and the valve wasnt even opening.As soon as I drove it out of my driveway with the new valve I IMMEDIATELY noticed the difference, as it was back to normal and felt like the car moved quick again without the knocking. But after about 20 miles, the light came back on [the car is still running perfect].Today I went to Autozone and had it scanned, and sure enough, code P0403 came up as EGR Valve Circuit. He cleared the code out, and I drove to a nearby store, and when I came back out and turned my car on, the code was back AGAIN.What's the problem?If you have an idea of something else that I should check, please give me an idea of where it is located.Thank you.
- if your valve was carboned up then you Dp sensor is probably clogged as well and that would cause the light to come on and it would give that code. You can more than likely take it off and clean it really well with something like LPS or brake cleaner...carb cleaner would work also
- Q:my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.
- The exhaust valves get hotter--the reason for looser clearances.Buster Brown is right about the rest.
- Q:i need to know the setting of the valve and a little advice on the up and down of the valves
- This is not a job for a back yard mechanic.Your valves have overbucket shims and require special tool and more important a selection of shims in .002 increments.Best to let a shop do this.You can save yourself about 1hr labour if you remove the fairing yourself before you take it in for adjustment. By the way the shims cost about $8.00 each but most shops have an exchange price.
- Q:When i was 14 I was diagnosed with a moderate aortic bicusspid valve. I am now 19 at my first cardiologist appointment I was still at moderate. Three months later when i went back in I was rediagnosed with a severe aortic valve. I have every symptom, and I'm getting ready to have it repalced. My question is what am I to expect after surgery. Will i be able to work if not is there anything I can do to have some sort of an income comming in?
- There are minimally invasive approaches, and there are many different techniques of valve surgery and all valve replacements, with choices to provide each patient with the best possible treatment.The patient will normally choose, with their surgeon, the type of incision, the type of valve and the technique. Valve repair versus valve replacement, with coronary artery bypass if necessary. The choices will normally depend on the patient’s opinion, their health history, and their surgeon's opinion. After successful aortic valve replacement, patients can expect to return to their preoperative condition or better. Anticoagulation (blood thinners) with a drug like Coumadin may be prescribed for 6 weeks to 3 months after surgery for those with biological valves, and for life for those with mechanical valves. Once the wounds have healed, most patients should experience few if any restrictions to activity. A patient will require preventative or prophylactic antibiotics whenever having dental work, and should always tell a doctor about their valve surgery before any surgical procedure.

- Q:I have a 1989 Jeep Cherokee with 218,700 miles on it and my engine has thick oily gunk on it, possibly from a leaky valve cover gasket, should I change the gasket? I have been told that this is normal and not to worry about, but from the amount of this gunk, I find it hard to believe this is normal. The top of the valve cover has a light covering of gunk, but on the sides and towards the bottom of the engine. it gets very thick and at some places you can't even make out whats suppose there. Does a leaky valve cover gasket mean that there is another problem going on?Can leaving the oily gunk on the engine cause any problems?Any info would be greatly appreciated.
- DIY method: pressure wash engine with a degreaser solution, remove valve cover, clean mating surfaces, apply a RTV silicone compound to the valve cover and install new gasket, reinstall valve cover, reinstall bolts taking care to not overtighten them, replace PCV valve (probably a good reasson why it leaks to begin with) clean jobsite and drink a beer. Non-DIY method: take to shop and pay about $150 for the trouble. Not a good idea to ignore an oil leak, it's just not.
- Q:One of the zone control valves in my heating system does not appear to be working. The thermostat is calling for heat, but no water is flowing. If the other thermostats call for heat, the valves seem to open as the pipes above the valve get hot from the water flowing through. The one that appears busted gets luke warm at best. All 4 valves in the system are fed from the same pipe, and the failed valve is the third in the series of 4 along the pipe (and #4 flows fine) so it doesn't appear to be something in the feeder pipe.Is there anything I can do to try and fix the existing valve, can I replace the valve myself? Would replacing the valve top of the valve (the green/gold portion) possible fix the issue (maybe a problem with the operation of the piston? Is there anything I ahve to do before removing the valve top aside from removing power to the valve?
- The first thing is to see if the zone valve is getting voltage from the thermostat telling it to open. Most are low voltage a/c current. If it is getting power and not opening you probably should change out the entire valve. Some have compression fittings and some have a solder connection. If it is a solder connection make sure the valve is open before you sweat it . You will have to turn off the water supply to the valve and the power and bleed off the pressure. Make sure the solenoid matches the existing voltage. Have fun.
