- Q: My friend had heart surgery and it was pretty serious. She got a new heart. Days later they checked her and discovered that she bursted a heart valve. The doctors say it's one she can live without. That really concerns me. The valves connect directly to the heart. Please help.. Will she be ok if she doesn't get it replaced?
- The most common cause of a heart murmur is a defective valve. There are thousands if not millions of people walking around with heart murmurs. My mother had one from the time she was 11 or 112 until she died at age 80, not from heart related issues. Your friend should be fine, as far as the valve goes anyway. I, personally, have heard hundreds.
- Q: I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project
- take the heads to your local automotive machine shop and have them do the valve job they will fix whats wrong with your heads.and for parts you will need a head set gasket kit from auto zone or summit racing,and new spark plugs wire's oil, antifreeze,belts water pump since you have the room to get to it now,
- Q: My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?
- I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.
- Q: Is there any treatment available for a leaky heart valve?
- i dont know, but i have one to. once a doctor told me if it gets real bad they could fix it with laser. i was on medication but quit taking it , it made my heart rate too slow. i got mitral vale prolasp. i dont know if i spelled that rite.if you have a heart doc. i would ask him to ease your fear. good luck.
- Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.
- First of all, the gas pedal on a fuel injected car is a misnomer. It IS an accelerator pedal, but what it really does is only to add AIR to the fuel that has already been injected. If you have to add more air to keep the engine running, then you have a fuel mixture problem, probably from the mixture control unit or a vacuum leak in the attaching air snorkel. You can easily remove and clean the EGR (Exhaust gas recirculation) valve with appropriate wrenches. It's sole purpose is to mix hotter exhaust gas from the exhaust manifold with the incoming air charge to improve the burning of fuel for emission control purposes. It is vacuum activated by higher engine speeds and may jam open from an over abundance of carbon present in the exhaust. You may want to check the operation of your PCV valve and it's hoses for the presence of a vacuum leak, which wuold dramatically affect the power and MPG's. Check your trouble codes at an Auto Zone or similar to see if any of your sensors are on the fritz. Also, specifically, check that your engine is reaching normal operating temperature and that the temp sensor is really immersed in the coolant. If your coolant is low, it doesn't signal the computer to lean out the fuel/air ratio. A good way to check for vacuum leaks is to go to a do-it yourself car wash and shampoo the entire engine bay with the motor running. Any bad plug wires or leaks in the vacuum system should show up now. If I were you I would change the plugs and put in some Bosch Platinum plugs and cork up the vacuum line that runs to your EGR valve completely. It only creates extra unwanted carbon build-up in your intake manifold, anyways. A thorough Gum-out rinse is called for.
- Q: Pressure relief valve on boiler is dripping.Starts to drip more when the boiler is turned on.Bad relief valve?
- Only to add what Steve said, make sure you have a pipe leading from the Safety valve to the floor, that way if the Safety valve let's go it won't be shooting straight at someone's face or other equipment. If you could, pipe the safety to a drain but by all means leave the line open, Put no other valve in the line to restrict what the safety is meant to do.
- Q: i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?
- Think okorder . Go on line an read: Function EGR Valve before you ruin the engine with a block-off plate.
- Q: i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?
- The answer Briggs gave is pretty much on the target except I believe he missed your primary question: will oil run out of the valve cover and get onto other engine parts. The answer to this is most likely but there are some precautions you can take to minimize the oil. Assuming the engine is fairly clean inside, the oil galleys should allow most of the oil in the upper head/valve spring area to drain back into the engine. If the engine has set and not been run for several hours (over night?) the majority of the oil will have drained out of the head area. There will be pockets of oil trapped in the upper head area but that most likely will not run out when the cover is removed. First thoroughly clean the valve cover(s) so no dirt is present to fall into the open head area. Get some absorbant towels (paper or cloth) and pack around the head below the valve cover gasket line to catch and absorb any oil that might ooze from under the valve cover when it is unbolted and removed. After getting the valve cover off, make sure the absorbant material is still in place and if necessary, you can absorb the pooled oil pockets still in the upper head area to prevent seepage from these area. Good luck.
- Q: I have pressure steady at 13psi --- water temp is normal range but the external emergency run valve has been dripping since i turned the boiler on this year? Expansion take was empty, so I forced water through and then drained it and reopened the valve.....I am stuck and getting concerned. Anyone have a suggestion?Would really apprecite it?Additional info:Boiler is a Gas Powered unit by MASTER from the 80's.....
- The TP valve will naturally wear out over time, if it has never popped open the washer inside of it has hardened, when you opened it it didn't seat properly when it closed back up, causing the drip. This is not an unusual or dangerous condition, the TP valve will usually wear out before the boiler does, it can be quickly and easily replaced. The valve will still function with a leak, but this reduces the efficiency of the boiler. DO NOT, under any conditions, DO NOT plug the leak by plugging the opening on the valve, this creates the potential for a very dangerous condition, let it drip until it can be replaced.
- Q: I am trying to bench bleed my master cylinder on a 94 altima...the directions state to attach the bleeding hoses to the outlet valves?? I haver four valves that merely state front or rear??
- All hot water heaters have what they call Anode Rods For more than 60 years, it has been used as a key part of the rust protection of a tank. The rods are made of magnesium or aluminum that's formed around a steel core wire and is screwed into the top of the tank. A lot of the times they are on the hot water outlet. You should have a dielectric union separating the galvanized pipe on the top of the water heater from the copper pipe for your house supply. You should be able to remove the anode rod from the tank and get a replacement from your local plumbing supply store. Most likely the sediment/ hard water deposits have deteriorated the rod and have caused corrosive deposits to clog your lines.
