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: and i want to but over size valve seatscan i do it in a 1991 chevy chenynne k2500: Jasons $1500 quote is way over priced. Valve seats crack due to heat and age. Its a common prob with chevy heads really. Price at a machine shop to replace the seats and do a valve job will be about $400 If your wanting to go larger on the valves, then you will need new valves ($75-150) Now why do you want larger valves in a stock head? Most chevy heads has 1.84 or 1.94 intake and 1.50 exhaust valves. I had 1.94/1.50's on my 355 making 505 HP, and running mid 11's 1/4 mile in a camaro. I have now stepped up to 2.02/1.60 It might be cheaper and better for you to buy an aftermarket set of heads with the larger valves if thats what you want. Aftermarket heads range from about $600 to 1200 a pair. I bought a new bare set of alum brodix IK 200cc heads for under $700, then bought all parts I needed to build them with for about $175

Q: i just bought a junky trumpet, didnt come with a mouthpiece... how can i tell that the valves work? They press in and dont stick, but im not sure about their functioning. Also there are no caps on the valves, will this affect playing? lastly, it has a stuck tuning slide, how can i get this to work again?: whilst i develop into in intense college, I performed on a 3C and had a particularly good sound. in my view, i could in no way visit a smaller, shallower mouthpiece to play intense. i could quite develop my chops and be waiting to do it on a deeper mouthpiece. In college, I switched to and nonetheless at present play a Monette B2, that's analogous length to a a million a million/4C, and characteristic an excellent sound, and might play a intense G (4 ledger lines above the staff) and up on it. i exploit it for any group I play in, marching, stay overall performance, musical theatre, etc... ultimately it boils all the way down to private preferrence. %. the mouthpiece that feels the terrific to you and nonetheless can provide a good sound. you do not pick it so great and deep that your variety and sound go through, and you do not pick is purely too small and shallow which you get too outstanding and tinny of a sound. wish this facilitates.

Q: My vehicle has 160,000 miles and has burned 2 quarts of oil at 3000 miles. Someone told me to change the PCV valve because sometimes a bad PCV valve can cause oil consumption. I appreciate your assistance.: It coming out of the valve cover(s) there maybe more than one. You can tell what it is by the way it bends at 90 degrees and to remove it just pull up on it it'll pop right out. If you shake it and it clicks. That's not your problem.

Q: i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?: Ford Mondeo Egr Valve Problems

Q: What are the benefits of changing new cylinder heads and exhaust valves in the Main engine of the vessel? I am now studying a vessel which has a problem with their main engine. Frequent repair of cylinder heads (they usually weld it) and exhaust valves are the ones they do. I need to further give the benefits to be submitted to the vessel's management for them to buy new cylinder heads and exhaust valves as a replacement for the welded ones.: It sounds to me like this ship has an ongoing exhaust problem (maybe an obstruction of the flow) Or a low volume of cooling water (look at the water pumps) About the only reason to weld a head would be because of a crack and the most likely reason for a crack is over heating likewise the burned valves! Assuming that the engine was assembled correctly What else would cause the over heating except one of the above! Before you put new expensive heads and valves on this thing check out the over heating ( just because the Gage never shows hot dose not mean that it isn't! If the welding and the valve replacement was done correctly then there may be no benefit at all in buying new ones a compression test would tell,but a REAL LARGE benefit in finding out WHY this would happen especially more then ounce !

Q: Describe a typical semilunar valve and tell how it works: Semilunar okorder /

Q: I have a Ford Explorer 4x4 2004 model.The check engine light soon has been on for two to three weeks, I finally got it checked and they said i need my ERG valve cleaned. They quoted it for around 50 bucks, which is fine. However, i dont get paid until a week from now. Will it be alright until then?What are the effects of a dirty/faulty ERG valve if not taken care of??There are not sputtering or anything abnormal that i can tell..Thanks.: If your truck runs, you can probably continue running it for a while (likely a long while), though you might pollute. If the EGR valve gets stuck open, it will drop your vacuum pressure radically. That will cause your engine to run roughly and inefficiently. If the EGR valve gets stuck closed, your smog system won't work right (you won't be recirculating the exhaust gas to re-burn pollutants. It is possible that the shop had no reason to tell you to clean the EGR valve. You might ask the mechanic if it is stuck open or closed. He might have suggested cleaning the EGR as preventive maintenance.

Q: i need exhaust valves material dimensinons of any car.: Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.

Q: I am trying to bench bleed my master cylinder on a 94 altima...the directions state to attach the bleeding hoses to the outlet valves?? I haver four valves that merely state front or rear??: The outlet valves are the bleeder valves behind the wheels the ones you open up when your bleeding the system.But to bleed the master cylinder mount it to the car and then fill master cylinder and then screw in the bleeder hoses at the locations where the metal lines hook up to the master cylinder and bend the hoses around back around to the top of the master cylinder so when your bleeding the master cylinder the brake fluid goes back into the top of it to get the air out of it.Then hook up your brake lines back to the master cylinder and bleed out the rest of the system to the wheels.Usually when doing this you start with the right rear bleeder behind that wheel but have someone there to pump on the pedal even when your bleeding the master cylinder first and then you do the rest of the system.On some cars bleeding the rest of the system starts with sometimes different wheels like the front and or the back.But on a usual bases you generally start with the right rear then the left rear and then the right front then the left front.But by bleeding the system check with a shop to find out what the bleeding steps are to bleeding the wheels outs at the valves each car is almost different to do.But the master cylinder is the easiest to start with when it comes to bleeding it but watch out when going to hook up the brake lines back to it because some brake lines are hard to hook up and what I mean by this the fiitting might get cross threaded when putting them
