- Q: Hi. I replaced my PCV valve but the hose it connects to is cracked at the end. It's still loose and I can pull it off with my hand. It is very hard to get it to stay connected. So my question is that while I am driving, what would happen if the PCV valve accidently disconnects from the hose? Would I still be able to get to a service center?
- in the short term, use a plastic wire tie to secure the hose until you can buy a new hose....you need to replace the hose.
- Q: Between these two Blow off valves around the same price, what would be the best choice for a pt cruiser.
- The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.
- Q: I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!
- Well if you talking about the water shutoff valves under sinks then you need to first shut off the water comming into the house at the main shutoff valve near the street , Or at a line comming into the house that connects up to the valve you are trying to fix or you may take a slight bath while trying to fix the valve that wont shutoff. Then Go to the shutoff valve you want to repair in that line where you shut the water off at and unsrew the handle at the base of the handle shaft using two wrenchs to hold both the nut on the shaft while using the other to hold the shutoff valve .this will prevent twisting the valve right off the connecting lines. Most of the time you will find it has a rubber gromet attached by a screw to the handle shaft.this is what you need to replace with a new rubber gromet which you can get in an assortment box at wal mart or homedepot or lowes for a low price. If you are using teflon thread or jointcompound you are repairing a Pipe joint leak where water is leaking externally of the pipe,not a shutoff valve leak .
- Q: I have a 79 ford F-150 and i was wondering where the pcv valve was my truck will start but it wont idle until its reached normal operating temp i was told that it might be my pcv valve is that correct or what else could it be. thanks
- I would not start at the PCV valve but check with your cooling system first. Check and replace the thermostat
- Q: Hey there in new england wth a blizzard on the way :(. I noticed a few weeks ago that my radiator in my bedroom was always cold. I have lived in this house for 11 years don't know why I am just noticing now. Anyway I discovered that the radiator valve in my room was closed. I shoudl have know it was closed for a reason. I turned it on Wednesday night. everything was fine until this morning. It started leaking thru the celing. my husband tightened it turned it back off and it was fine for a while until it started leaking again! I have since turned the heat off. What can I do now? Did I mention we are bunkered down for a blizzard here? I won't get a plumber out here for days and I fear with the blizzard winds if I keep the heat off the pipes will freeze! Help any suggestions? why didn't it stop leaking after we turned the valve off again??? I am so freaking out right now!
- Turn the radiator water valve back on and then while holding the tap on tighten the nut until it stops leaking. Sometimes(like us) as the valve gets older the packing inside the valve starts to break down and when you turn the valve on it turns the nut open a little bit with it. Just tighten it up and get you heat going before you and your pipes freeze. Good Luck Richard
- Q: Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.
- This people above do not know much about EGR's which one of the main purposes is to lower combustion temperatures by introducing exhaust fumes into the intake. So yes it can add to the overheating problem. source GM tech
- Q: List all the brass instruments with valves? Thanks. I need it for the history exam -.-
- trumpet tuba baritone thats all i no:D
- Q: 1994 Chevy K1500 P/U 5.7 liter 350 4X4 5 speed. When the truck is under a hard pull the valves start knocking, the knock sensor adjust the timing and the check engine light comes on. The code for the light is not detecting knock sensor. I have changed the pcv valve (which was suggested) and no change. This has went on for about 5 years. Doesn't matter the grade of fuel I use. Routine maintance and tune ups have been done to this truck. The converter was taken off 7 years ago because it was clogged. The truck runs rich after the timing adjust. The light resets itself when it is turned off. ( the code is saved)
- Excessive carbon build up on the valves may also be causing pre-detonation which the knock sensor will not be able to correct. If it is a high mileage or a rough service motor it may be time to open it up and see if it's time for a valve job, or possibly a rebuild.
- Q: My mum (73, non-smoker, not overweight) has been diagnosed with 2nd degree aortic valve stenosis 5 years ago. Now deteriorating. Her cardiologist sees her every 6 months and strongly recommends surgery. She is too scared as dad died during a coronary bypass op. Any tips how to gently make her feel better about the op? She heard on the radio that some valve replacements can be done via catheter, not necessitating open heart surgery and heart-lung-bypass. Is that true for aortic valves and is it likely to become mainstream soon? She lives in Germany, so I guess good centres would be Munich, Wuerzburg and Heidelberg. Any views very appreciated!
- Unlike the mitral valve which can often be repaired, the aortic valve usually requires replacement. Once the decision is made to proceed with surgery, choices regarding the type of artificial valve (prosthesis) used should be considered. In broad terms there are two types of artificial valves or prostheses: mechanical valves and biological valves. A number of excellent mechanical replacement valves or prostheses are available today. Most surgeons have a particular preference for one valve over another related to technical factors (how they are sewn into place), however from the patient's point of view there is little if any difference between valves. The principle advantage of mechanical valves is their excellent durability. From a practical standpoint, they do not wear out. The principle disadvantage is that there is a tendency for blood to clot on all mechanical valves. Therefore patients with artificial valves must take anticoagulants or blood thinners for the rest of their life. There is also a small but definite risk of blood clots causing stroke. The decision on the type of valve used should be made in conjunction with your cardiothoracic surgeon and your cardiologist. Ultimately the choice will depend on a patient's preferences, lifestyle, and individual risks as determined by age and other medical conditions. I advice you to consult surgeryplanet, which is a global healthcare facilitator. They can give details about this surgery and the good centers for the surgery.
- Q: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?
- There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.
