- Q:What is a valve mismatch in cars. code 300, 302, 420. All togather. Mechanic is telling the truth to do tune up and all. Is iT valve itsef? What is a (bad) coild? MITSUBISHI MIRAGE 2000
- Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
- Q:my valves are making a taping sound and i lost a lot of power and need to know will lose valves make me lose power so can someone tell me what they are seat on thanks
- although okorder / You don't want to go opening up this motor without one. I've done alot of motor work on my bikes, and still use one when I open them up. How long have you had this quad? Is it a noise that recently started? How many hours on the bike? or has it been like this since you've owned it? Typically, these high performance motors inherently are noisy anyway....so it very well could be normal. If not normal, the noise you are hearing could be a variety of different causes, as there are many moving parts. Timing chain, timing chain tensioner, valves, valve springs, piston slap, rod bearings can all cause tapping and knocking noises. So, unfortunately, there's no easy answer to your question.
- Q:What are better valve cover gaskets for a car? Cork kind? Or the rubber kind? Or either rubber/cork kind?
- For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good
- Q:Anyone know how to stop this from happening? I have gone through 4 since March.
- are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.
- Q:Okay, I got this lawnmower its a craftsman with a briggss and stratton engine, and I use this mower to cut grass in the summer. My question is, I have to get this mower serviced like every 2 weeks. See, the problem is always the valves comes out of adjustment. It only has 2 valves, and a long time ago, I broke one of the studs for the valves. And some guy put another valve on it. Ever since then it hasnt ran good. Iv'e took it many times to get it worked on, and it will run great for about 2 weeks. Then the valves go out it's very hard for it to turn over, and it wont run. Whats the deal here? I hear that you should only have to adjust your valves once a year. What could be wrong?
- haha they have been given me 2 valves briggs and value trans will bypass next shrink your cost now sorry I hate craftsman now they bit me and distinctive others guess ur mower is green with the cup holder,
- Q:I went look at a car, and the guy selling the car said that the engine valve is leaking. Is this a big deal? How urgent would it need to be fixed? How much would that cost?
- depend which valve it is exaust/inlet? but any valve in the engine would be pricey as they have to take the head of this meens a lot of labour and new seals.
- Q:When I went to cardiologist he said i had normal EKG, excellent blood work high HDl 58, low triglycerides only 51, and LDL was like 71, ejection fraction of 65% he said I was fine but he said I had mild mitral valve prolapse. DO I have to worry abt the mitral valve prolapse? Im healthy and can I live a normal long life any opinions?I dont smoke, dont do drugs, no family history of Heart problems just some cholesterol but mine is low so Im good
- i wouldn't worry too much at the moment your cardiologist and you dr will keep a close eye on it Medication can't correct a deformity of a mitral valve. such as diuretics are available to relieve fluid accumulation in your lungs or legs, which can accompany mitral valve regurgitation. High blood pressure makes mitral valve regurgitation worse, so if you have high blood pressure, your doctor may prescribe medication to help lower it. Following a low-salt diet helps prevent fluid buildup and helps control blood pressure looking going back yrs ago they used to replase them srtaight away but the diffrent tenics now they dont do it straght away but try to sort it with medication it can be repaired if the heart is not pumping very well but this is how a repair is done if your heart is not too bad Your mitral valve consists of two triangular-shaped flaps of tissue called leaflets. The leaflets of the mitral valve connect to the heart muscle through a ring called the annulus. The surgeon can modify the original valve (valvuloplasty) to eliminate backward blood flow. Surgeons can also repair the valve by reconnecting valve leaflets or by removing excess valve tissue so that the leaflets can close tightly. Sometimes repairing the valve includes tightening or replacing the ring around the valve (annulus). This is called an annuloplasty. It's important to have an experienced surgeon perform mitral valve repair i hope you find this an help to you but as i said you dont have to worry too much yet you have a good chance with your tests you can lead a pretty good life and if need be they would do more if it came to the worst hope this as helped you
- Q:I'm in the process of replacing my dishwasher but I have a problem. I followed the water line from the dishwasher to under my sink and found a red valve that was completely straight, so I turned it to the right as tight as it would go and tried removing the hex nut connecting the line to the dishwasher. Maybe i'm wrong, but there is a lot of water coming out of the line and I don't think it's supposed to. I easily filled up a bowl you would use to mix cakes and it was still going! So, I turned the valve back to straight across thinking maybe someone else turned it off (my dad), and tried it again but the same thing? What am I doing wrong and what should I do to solve this?
- If it is a quarter turn valve , the lever should be across ed the valve ,not in line with it. If that's not working for ya, turn the main water valve off. then drain the water pressure by opening the faucet at the highest point and the lowest point in the house. now it's time to change the dish washer. Good luck it shouldn't be that hard.
- Q:Leak in Heart Valve ?i was told by my doctor to to do a ultra sound on my heart a few weeks ago, wehn i finished the ultra sound the lady that did the scan asked if i had any type of heart disease in my family, and i responded that i dont, she said that i have a leak in my heart valve, but that was all, i dont have an appointment with my doctor til two weeks from now, i THINK i feel shortness of breath, but i feel like this may all be because im scared ...... main thing is has anyone had this or know anything about this is it dangerous, deadly ? should i be scared ?
- It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.
- Q:I am being sent for a level 2 Ultrasound Thursday because my previous US showed one of the babies valves was enlarged. She said all 4 chambers were there but she was very vague on what this means. Care to shed some light?
- ?UPDATE? We went to the US today and the heart was 100% HEALTHY!! There was nothing wrong with any anatomy of baby girl. The doctors there said they are completely confused as to why my Doctor would tell me the baby might need heart surgery when she wasn't even 100% on the issue and even if it was due to positioning like she 'claimed' at first, then a Level 2 US wouldn't be necessary. I'm just so grateful and thank God that my baby is ????!
