- Q: 1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.
- Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
- Q: My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?
- Your van runs good because the computer has learned the driving style, if your battery goes dead and the computer resets, itd be about 200miles before it relearns the vacuum tolerance , and because the idle air control valve is disconnected it must of been when the solenoid was in the right spot. Because the idle air control valve is disconnected, your gas milage will suffer and your computer wont be functioning right, not being able to compensate form different road conditions/weather/wide open throttle.
- Q: Model 28 BS 12.5 HP engine intake valve sticks. Please advise.When under a full load like tall grass, it runs great, but when the load is not as heavy, the intake valve sticks open, spewing gas back through the carb and mis-firing.
- Weird that it runs better under load. Try spraying carb cleaner into the carb while it's running to see if it can remove some carbon build-up or whatever might be causing the lifter to stick. Be careful about how much you spray..too much and the engine will shut off. Spray it until it sputters, let it recover, then spray some more. Check the spark plug. A badly fouled, improperly gapped plug can cause similar problems. Of course clean/replace the air filter.
- Q: Grade seven, my teacher's a pain. She didn't even explain the 'sets', we just know what valves are in general. So.. which set of valves closes when the ventricles contract? Relax? Thank you so much!***10 POINTS***
- There are two types of valves in the heart: the atrio-ventricular (AV) valves and the semi-lunar valves. There are two AV valves: the tricuspid between the right atrium and the right ventricle, and the mitral (also called bicuspid) between the left atrium and the left ventricle. There are also two semi-lunar valves: the pulmonic semi-lunar, between the right ventricle and the pulmonary trunk (artery) and the aortic semi-lunar, between the left ventricle and the aorta. During diastole (the relaxation phase), the AV valves are open and the semi-lunar valves are closed, so the ventricles can fill with blood. During systole (the contraction phase), the AV valves close and the semi-lunar valves open so the blood can be pumped around the body.
- Q: My boyfriend just went to his heart doctor and his tricuspid valve is leaking because of his pacemaker wire. They are saying that its moderate to severe. We are trying to decide on what moderate to severe really means. They said the same thing when he was at the doctors in June.
- Tricupsid regurgitation (TR) can be mild, moderate or severe. The tricupsid valve is located on the right side of the heart and separates the right atrium from the right ventricle. During the contraction of the right ventricle, the tricupsid valve is normally closed and does not allow blood to travel backwards into the right atrium. The severity of TR is determined by the amount of blood that regurgitates back into the right atrium instead of going into the pulmonary artery like it normally should. If a small amount of blood is regurgitated, then it is considered mild. If a significant amount of blood is regurgitated then it is considered severe. Moderate is between the two. Cardiologists frequently use the term moderate to severe to indicate that it is somewhere in the middle.
- Q: I'm picking up euphonium (brass instrument) after a 5 year hiatus. Can I still use my old valve oil and slide grease (Trombotine)?
- okorder /
- Q: My valve covers are leaking how do I take the intake off my v6 firebird?
- You probably don't need to. Just tighten the screws up a little bit. several years, GM decided to use gorilla snot (silicone) instead of real gasket material. THis was a BIG mistake. I don't know if this is what you have. If this is so, Fel-Pro makes wonderful REAL gaskets. IF you need more info, check with local libraries for the ALLDATA data base. It shows you everything in great detail. Sometimes, oil gets forced through covers due to a clog in the oil pressure relief valve, which is part of your oil pump. You should do a chemicla engine de-sludge to clean this thing out as a preventative to futire woes. THen switch to a good synthetic oil, like Mobil One or Pennzoil Platinum. Your engine will just LOVE you for it!!!
- Q: im looking for the egr valve on a 97 mazda 626 its not in top of engine like other cars where can it be?????o and its a 4 cylinder
- okay your gonna look at your intake manifold. Then locate where your air intake connects to the throttle body. Look around the throttle body and you should see the egr valve it will be hidden by your air intake but if you look hard enough you'll find it and also if you see in vacuum lines running around there, they will point you in the right direction because your egr valve has two vacuum lines that run to it. hopefully that helps.
- Q: is there any way to buy refills for empty valve oil bottles, such as holton or al cass
- I wouldn't bother with that. I would go to Woodwind/Brasswind, and get their brand of valve oil. Very economically sound, and a very good product. Why go to all the trouble of getting bulk stuff and trying to put it into those little bottles. Get the company brand stuff. It works wonderfully and is half the price. Sometimes you pay for the names al cass, or holton, when all you are getting is just oil.
- Q: I have a problem with standing water that keeps puddling up and never drains under where my valves are located for my sprinklers. What do I do? Should I just put 3/4 drain rock on top? Please help?
- Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
