Q:how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?

First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.

Q:List words that rhyme with valve...I need these.

salve, like to put on a wound or something

Q:I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.

i have seen many types of valves on an everyday basis. and i havent even seen one like this. its most likely a cheaper knock off brand valve. you have enough room to replumb a new one in quite easily. if you do not have enough room right before the valve to just cut it out, cut the pipe on the other side and unthread the valve from the threaded fitting. then buy some fittings and pipe and replumb it. you have a lot of room to work on it. i doubt you will find the same valve to part it out with. use either a Hunter valve or a rainbird valve avoid toros, orbits, weathermatic, and lawn genie parts. good luck and just take your time.

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?

Q:Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear

Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.

Q:Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...

Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.

Q:hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??

Cochlear implants aren't valves, they're implanted behind the ears, they improve hearing in people who are hard of hearing. An artificial valve replaces a heart valve, which controls how much blood flows in and out of the heart.

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

If it is MILD mitral valve prolapse then no you don't need to worry. Most likely what your doctor meant is that you have a mild heart murmur which is not dangerous(that is only a guess since i don't know exactally what your doctor said and am not physic). If there had been dangerous or to worry about you doctor would have told you and explained the issue. Why didn't you ask him about it when he told you? Here is some information about this topic ?Mitral valve prolapse (mitral valve prolapse) is the most common heart valve abnormality. ?Most patients with mitral valve prolapse have no symptoms and require no treatment. ?Mitral valve prolapse can be associated with fatigue and/or palpitations. ?Mitral valve prolapse can often be detected by a doctor during examination of the heart. mitral valve prolapse can be confirmed with an echocardiogram. ?Patients with mitral valve prolapse are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery If you are concerned then go and talk to your doctor about it more. Your doctor is a professional and should be the one to explain it to you. I am not a doctor, nurse or cardioligist all my information comes from Personal Experience and Research.

Q:I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help

Yes you can drive the vehicle with 1 broken bolt to the valve cover. The valve cover should leak a little due to the lack of tension at the broken bolt. The leak may be minimal. If you remove the valve cover use silicone as a new gasket, you can use extra silicone at the broken bolt. Allow the silicone to dry before tightening the valve cover bolts. The extra silicone may stop any oil to blow by the broken bolt problem solved. The valve cover does nothing more than stopping oil from leaking. A leaky valve cover nothing more than leak will not affect how the vehicle runs. The cost to have the broken bolt replaced should be around $100.00 (if the broken bolt is accessible) The cost is strictly labor (time). About $100.00/an hour. To repair this you have 3 options; 1) You can extract the bolt. This may be very easy depending on the accessibility (can you get a drill over the broken bolt?). If you can drill a whole in the broken bolt, you can lightly tap an extractor into the whole with a hammer. Then with a wrench or a pipe wrench you can try to extract the bolt by turning the extractor counter clockwise. Use WD40 or a catalyst to loosen the broken bolt. The longer the catalyst (WD40) has to work the better. ie- spray the broken bolt 3 or 4 times a day allow the oil time to loosen the broken bolt. You can purchase extractors at any auto parts store for about $15.00 I can't emphasize the importance of WD40 enough!!!! 2) The 2nd option is to use a healy coil. You would need to drill out the bolt to a specific size (the healy coil package will tell you what size drill bit to use). After drilling out the bolt you can insert a healy coil that will allow you to use the same size bolt you just drilled out. The healy coil package will have detailed instructions. This is very easy to do! Healy coils can hold a lot more torque than valve covers require. 3) The third option is to drill out the broken bolt completely tap new threads insert a larger bolt.

Q:So I tried to go skydiving last weekend and they told me know because I have mitral valve prolapse. I've had it for years and it's never really been a problem for me, I just have chest pains sometimes and feel palpitations. What would be the danger of not telling the skydiving place about my problem the next time I go in? I know I should tell them, but I want to skydive. What could happen to me if I jump? No lectures about what's right and wrong here please. I just want to know what's the worse that could happen?

There are many people with mitral valve prolapse that never have symptoms related to it and never have any problems as a result. Mitral valve prolapse can lead to the backflow of blood through the mitral valve known as mitral regurgitation. This can potentially lead to abnormal heart rhythms, such as atrial fibrillation. The concern with skydiving is that it would lead to a surge of adrenaline resulting in increased heart rate, strength of heart contractions and overall workload of the heart. If you have MVP without regurgitation, then your risk would be similar to the general population. If you have regurgitation it depends on the severity the regurgitation. If you have mild regurgitation, then it also should not be a problem. If you have severe regurgitation, then you could run into problems from the increased workload of the heart. In this case, I would suggest you discuss it with your Cardiologist. It is unlikely that you have atrial fibrillation. If you by chance do, then it depends on how well your heart rate is controlled. If there is any doubt, then ask your Cardiologist. Good luck.
