Q:how do i gap valves on a 3406B motor. ?
NO, valves does not contribute to blow by in this way.Blow-by is the compression of the cylinder getting past the piston rings during compression. Adjusting the valves is a procedure of the induction and exhaust systems. All engines experience a little blow-by which is supposed to pass through the PCV valve ventilating the crankcase. GOOD-LUCK!! BRILLIANT!!!!
Q:Volvo valve cover replacement?
valve covers are easy to remove and replace. don't pay 650 bucks for that. yes, you can use the red sealant, but I would suggest high temperature sealant, usually comes in black, it's oil resistant also. just move anything out of your way, unbolt the valve cover, clean the surfaces off the gasket will touch (cover and engine) apply gasket maker and re-attach.
Q:How do you get a marching baritone's first valve to go down?
I have played for over 30 years and have a few to many horns. But I love to play. Sounds like its time for a bath. Take your horn to the bath tub. Fill the tub with warm water and a little DAWN dish soap. Lisen to me and buy DAWN, not something else. Palmolive tasts nasty, and the others do not cut the grease on the horn. Gently take out the valves and all slides. Lay them on an old towel. Lay the horn in the tub on an old towel so you dont scratch the tub. Let it soak. While the body soaks. Wash the valves. The valve might unscrew off the top stem. This would be great because you do not want to get the felt or corks wet. Be very gentle and careful, use an old white sock to scrub the old oil off the valve. Now that the valves are washed, rinse the valves with clean water. Now, take the old white sock that you just used and twist it. Then you can feed this into the valve case on your horn. Pull it through each of the three valves a few times. If you are realy good to your horn, you may even buy a snake made for cleaning trombones and baritones and run it through every pipe on the horn. Now rinse and dry everything. There should be no oil or grease left on the horn or the slides. If you find any go back and wash it off. First grease up the slides with slide grease or lanolin. Then oil (not grease) the valves with a good quality valve oil such as Blue Juice, Holton or Al Cass. Use just a few drops of oil on each valve. You place 2 (Two) drops on at a time and gently slide the valve into the horn. Spin and with any luck it will play like a dream. Now, you need to stop eating before you play. And never oil the valves through the hole in the bottom, that is where all the dirt is going. If you must, oil through the leadpipe. I remove the valves after I play and oil them. They are always ready to play this way.
Q:boiler bleed valve replacement?
You may be able to do this but there are usually two pipes going to the radiator and they may be tied in with a radiator on another floor. Be prepared for some water to come streaming out and do this when there is no hot water in the system. If you have the new valve ready to go with pipe dope or Teflon tape on it you will not get too much water coming out and it will not be under much pressure if you remember to shut off the water supply going to the automatic filler valve at the furnace. Plastic sheets and towels or rags should be in place just in case to catch the water and don't panic or it will take you longer to get the new valve started in the hole. A helper with a thumb to go over the hole to stop the water flow and give you time to do what you need to do may be required so have one of those handy as well.
Q:What is a purge valve in cars?
i would guess on avg 100K miles. But hey, my girlfriend has a 2006 altima and the starter went bust. My 98 acura still has it's original starter (honda uses great oem parts). things go depending on driving conditions and what we in the auto parts stores call flukes. Like a 2007 pontiac that needs a new ignition coil. That's why aftermarket companies continue to make parts for cars. no one wants to go to the dealer.
Q:EGR valve removal of a 1997 Lincoln Continental?
I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.

Q:how do you reconnect the heater valve on a 1997 ford ranger 2.3l 4 cylinder?

Q:I can get my trumpet valves unscrewed :OOOO?
Well on the valves you will see there are caps on the bottom and top of the valve. The top cap (it is located at the top of the valve itself, not the button you press - it is the cap that the button lands on when pressed) you unscrew that and take the valve out to oil it. Just make sure you put it in back correctly, if you put it in incorrectly it will not play properly. Also don't drop or dent the valves as they are very delicate and the smallest dent can damage it. Make sure that when you unscrew it that you only use your fingers. DO NOT use any tools to get it unstuck otherwise you can damage the instrument. It would be best for you (because you're new at the trumpet) to take it to the local music store and ask them how to take care of a trumpet. I am sure they will be happy to show you. Hope that helps
Q:Insufficient flow EGR Valve?
It could be two things. The exhaust gasket coming to the valve or the vacuum coming to the valve. The egr did not need changing. Without the proper tool to check it out. I can not say which it is or how to repair. It need to go to shop where the proper test can be use to find what need to be repaired of replaced Most likely it will be a one way vacuum valve, that is not working right.
