Q:i was told my egr valve needs to be replaced, so im wondering if the system cleaner will help at all. thanx: Not really. The EGR valves on newer cars have an electric solenoid that moves the plunger up and down via advice from the computer or engine management system. Probably 90% of the time the valve has a piece of carbon stuck in in that broke off iinside the intake manifold and or gas passages in the intake manifold leading to the EGR valve. They can remove the EGR valve and clean it out and reinstall it. A bad EGR valve will either have a bad solenoid coil, or the valve plunger is burned from the hot exhaust (from age and high mileage) gases not giving an air tight seal when it should be closed at idle. A fuel system cleaner is a good idea every 3K miles especially if you buy the really cheap gasoline that has a lot of alcohol in it. The alcohol creates more soot than pure gasoline or gasoline that has detergent added and this soot leads to the little carbon pieces that grow and collect in the intake manifold and on the injectors. Good Luck!

Q:The water shutoff valvue has a slow leak where the hose connects. Its right were the hose to the tank connects to the shutoff valve.....I also noticed when I close the shut off valve it doesnt stop the water completely. Does the whole setup need to be replaced, and if so, is it difficult? Or will just replacing the hose correct the leak?I figured the constant running wasnt a huge deal if there was no leak because you leave the water on anyways, so there is always constant water pressure there.: I'M plumber : sound like just need to replace the gasket in both ends of the hoses,some times this get worn or not tide enough

Q:can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry: Pressure Safety valve and Pressure Relief Valve are essentially the same. When fitted on a pressure vessel they limit the internal pressure to specified limits. When the pressure exceeds a set value they open to release the pressure. Some types will maintain the pressure (Like the pressure regulator on a pressure cooker) others will release all the pressure. Temperature Safety Valves are used in boiler type of vessels containing a boiling liquid, which generates the pressure (Again like a pressure cooker). Usually there is an equilibrium between the pressure and the temperature. In such applications a temperature responsive valve is used to control the inside pressure to safe levels. If based on thermal expansion, they can regulate. Otherwise a fusible alloy just melts and releases all pressure in one go.

Q:It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.: There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.

Q:Between these two Blow off valves around the same price, what would be the best choice for a pt cruiser.: The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.

Q:And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :): 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:Steam is a gaming network and valve is a company, but what else? I think that it might be nothing; they both suck at working.: I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)

Q:Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?: Nope - the atrioventricular valves always seperate the atrium and ventricle, and the pulmonary valves, at both exits to the heart, will always stop backflow into the ventricles. They maintain similar functions on both sides of the heart.

Q:I had the EGR valve and solenoid replaced and I'm not sure they needed to be replaced.: The EGR valve diverts exhaust gas back into the intake manifold to take up space and prevent the formation of NOx, a polluting gas formed inside the cylinder at temperatures above 2500 degrees.

Q:Or could you put a blow off valve on a supercharger?: No an No
