Q:Are valve cover gaskets easy to change?
Take your time when changing the gaskets. You will more than likely have to disconnect things. Make sure if you remove something it is put back. If you have to remove the spark plug wires, number them. From front to back, the left side is 1-3-5-7 and the right side front to back 2-4-6-8. I mark my wires with a sharpie but they are red wires. I use to use wooden clothes pins and write the number on the clothes pins. If you get the wires mixed up you'll have to get the firing order to get them back to the right cylinder. Good luck, you will appreciate your vehicle more now that you know the work is done right.
Q:Dangers of mitral valve prolapse?
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.
Q:how to calibrate a pneumatic control valve?
One minor point to add to Artsupremo's answer. Valves can be either air to open or air to close. With one you start with the valve closed and the other with the valve open. The procedure is the same for both types of valves, I just wanted to clarify that point.
Q:The component in the cylinder head that holds a valve in place and prevents the valve stem from moving side?
valve guide ase certified.
Q:Radiator valve is constantly spitting water?
The little valve needs to be changed with a new one,that valve has a small leather inside and it is to spit out water and air until the leather gets wet ,and then stops, then when the leather gets dried out ,it will do the same thing again and again, This is a auto radiator air bleeding type valve used for many years in radiator heating systems................Ok.......Mel........ Hope this helps you...

Q:97 Neon - Canister Purge Valve?
Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
Q:if i took off the little rubber hose connected to my egr valve,and the egr has no suction?
The EGR valve needs to be closed at idle. There should be suction in the hose, opening the valve only at cruise speed. On SOME EGR valves, you can stick your finger in the diaphragm and open it manually. The engine will sputter when you do this. I saw a tester do that at a smog check place. Otherwise, they have to use a little device that hooks up to the valve and sucks on it to test it.
Q:95 cougar xr7 EGR valve?
Go to a library that carries the ALLDATA data base. This amazing system has all information you will ever need. Even secret recall campaigns can be found here. Anyways, you are wasting your money to replace the EGR valve. For the most part, they can just be cleaned out with a solvent like Gum-out or butyl cello-solve and returned to service. Usually, these valves get gummed up when the IAC valve is dirty or you are using cheap gas and/or cheap oil. You are right about being metric, but a 13mm is the same as a 1/2 inch. A 14mm is the same as a 9/16 inch. You can even clean this valve by using Amsoil Foaming Cleaner through the intake manifold with the engine running full warm. Eventaully, this cleaner will penetrate the valve and allow it to close. You can tap it lightly with a mallet. Follow with a Gum-out chaser. Good luck!!
Q:Does anyone know how expensive a valve job is on a 93 BMW 525i?
You bet it will! A valve job may uncover valve guides that are out of specification. In which case the old guide hole will have to be drilled out and the guide hole honed, new bronze / nickel or hardened steel guides pressed back in. An ordinary valve job is relatively straight forward and easy but the labor involved with the tear down a new head and valve cover gasket without valve guide repair will run nearly $1,000 at a BMW dealership and 20 -30% less at a private mechanics shop. Most private mechanics AND dealerships do not do the actual valve job. The cylinder head with the valves are sent out to an automotive engine machine shop where the actual work is done. The dealer or private mechanic does the disassembly and reassembly of the head back on the block and gets the car running again.
