Q:valve gasket nissan altima?
The part itself is less than $100. It's a little rubber gasket that goes inbetween the valve cover and the engine block to make a tight seal between the middle and top of the engine. Depending on which engine you have (the 4 or the V-6), it can be a VERY simple fix with about an hour's labor because the valve cover is on top. However, some (very few) cars require you to remove the motor to get to the cover. If this is the case, 7 hours seems about right.
Q:Can anyone tell me the difference betwen these valves?
Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.
Q:What is a Valve Job?
a vale job is nothing it means nothing you dont get a valve job you get new heads... are rarely do they cause actual not functioning of the car. you have an old car that has seen better days. and age is catching up to it. the car itself is not the best made car and at best im surprised it hasnt hit the junk pile yet.
Q:What Does It Mean To Need A Valve Job On A Car?
i own a repair shop and what they mean when they say this, is that the head is taken off if it and the valves re-ground,and re-seated,and new seals put on them what this does it re-stores the compression on the upper end of the engine back to where it should be,as long as the piston rings aren't worn out in it,this usually works well,in some cases though it will make an engine start using oil,because it puts pressure on the upper end of the engine,and if it has any weak rings in it,this will make it use a little oil so be careful if you buy this one,keep in mind that a vale job doesn't always help one,it might run better,but can use oil later on ,this happens occasionally ,especially on higher mileage vehicles,and the cost of it would be around 600 bucks ,so make sure this car is worth it before you buy it,good luck with it hope this helps.
Q:what is the proper type valve for a main shut off inside a house?
Older homes will have a gate valve, newer homes would use a ball valve. Any type of valve would be proper as long as it seals.
Q:Head gasket and Valve cover gasket the same?
Depending on the material..If it is should change it every time..if it is can be reused...but what I don't understand is why do them have to take the valve cover off to replace the head gasket.
Q:How do you clean an EGR valve?
You will have to use an appropriate size ratchet wrench set. The valve is held in place by 2 bolts, usually. It is round and flat, and has a diaphragm inside the metal cannister. Once you have removed it, invert it. It will be full of unburned carbon which is easily removed with spray Gum-out and a small brush. If you are unlucky, and the internal diaphragm has broken, you will need to replace the valve. This is pretty rare, though. EGR stand for exhaust gas recirculation. This is what the thingy does. Under acceleration, vacuum from the engine causes the valve to open and scavange exhaust gas from the attaching pipe. Usually, and I should not write this, I just plug the vacuum on these things to prevent them from opening at all. Then I install a set of Bosch Platinum, Fusion or nippondenso Twin Tip plugs. This will reduce pollution, anyway, which is the goal of having an EGR valve. WHen it is diconnected, no carbon will get sucked back into the intake system, and the engine will stay cleaner inside. If you are smart, you will begin using Mobil One 0W-30 oil. This will improve your gas mileage, keep the inside of your engine cleaner, and you will only need to change it once every year or so. This oil will help prevent the formation of unwanted sludge and carbon deposits. You will be amazed at how much gasoline you end up saving!!!
Q:why would oil be leaking from the blow off valve?
vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
Q:what are symptoms of bent valves?
if it bent the valves it probably wouldn't run at all. it sounds like you may be off a notch on the belt timing. to be sure you didn't bend the valves you should check the compression. if valves are bent there won't be any compression. hopefully you didn't. I don't access right now to see if it's an interference engine or not.
Q:HELP!!! trumpet valve stuck?
You could just get a screwdriver and drill it into the bottom of the valve till it comes out. Its not damaging anything because there are no air pipes going through the bottom .
