Q: where is the bleed valve in a 97 taurus????thank you: Which okorder put in your car facts and go to repair

Q: Is there a way to test the EGR valve to see if its still good ? and working right .: Yes there is. Disconnect the rubber hose on top of the EGR valve. Connect a hand-held vacuum pump to this fitting. Start the engine. Slowly apply vacuum to the fitting on the valve. While applying vacuum with the engine running at idle speed, the idle speed should drop or the engine may even stall. In that case the valve is working. If the engine speed doesn't change, the EGR valve may be defective, or EGR tube may be plugged with carbon, or the passages in the intake and exhaust manifolds may be plugged with carbon. In this case remove the EGR valve from the engine. Again apply vacuum to the EGR valve and observe the stem on the EGR valve. If the stem is moving, it can be assumed that the EGR valve is ok. In that case clean the EGR tube and the intake and exhaust manifolds passages Hope this will help you.

Q: How much would it cost to get a new valve cover gasket on a 1993 Nissan Quest van?? I know of a van for sale, but they said it might need a gasket soon. How much plus labor, average, do you think it'll cost? Thanks!!: The valve cover gasket (parts and labor) is about $100 - $200 for the left side and $300 - $400 for the right hand side, but be sure you didn't misunderstand and the failing gasket is actually a head gasket. Those are a big deal: $1500 - $2000.

Q: what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?: From 0 lash turn the rocker arm nut 3/4 turn. Before you start, lay some rags under the engine to ketch the oil. The engine needs to be running. Loosen each nut until you hear the rocker arm stat to click, then tighten it slowly until the clicking stops, your now at 0 lash, now tighten the nut down 3/4 turn or 270 degrees, don't do this to fast the lifter needs to adjust. After adjusting, take a center punch held at 45 degree angle and punch the stud and top of the nut, this will assure the nut stays adjusted and wont back off. Put the valve cover on and wash the oil off, a spray can of brake cleaner works great. Remove the rags and your done. Happy boating. .

Q: do I need a new water heater or can this ne be fixed?: you said you tripped the valve-meaning opened it up then closed. try taking i small hammer and tapping onit on the sides. sometimes you will get minerals or a little dirt stuck up in there. if it doesnt stop dripping after that then just replace it. go to your local hardware store and ask for a pt valve for a hot water tank. make sure you specify for a hot water heater as the valve for a boiler is a different pressure. shoulr run you about 15-20 bucks. turn your water supply incoming off. drain the water from your old valve till water stops becuase now your below that part. unscrew the old vave out. apply pipe dope to the threads of the new one and screw it in. using a pipe wrench tighten it in. now turn on your fill and bleed air from your faucet. you should be all set

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.: if actuality be told whilst your valves close, there is a few returned pass instead of all your blood being pushed forward.. gentle regurgitation often does not reason challenge, yet you may get regarded at each year to visual show unit if it gets worse or no longer. you does no longer ought to get valve replace surgical technique till it extremely is reasonable to severe. if so, you will have the flexibility to observe with the aid of fact it could reason shortness of breath and because your blood pass isn't optimized.

Q: Could my subs kill my EGR valve? I replaced my O2 sensor and my check engine light didn't go off. So I had it checked again and the same problem was still there. It said that all the cylinders were running either rich or lean..... I can't remember. But I was told it could be the EGR Valve so I replaced it and for about a week the check engine light was off.Now its back on. Had it checked again and the same deal was going on. Oh there was also a low voltage reading..... which is why I'm thinking its my subs.So could it be my subs that keeps killing my EGR valve? And any solutions will be helpful. I don't want to have to replace my alternator because its in an extremely tough place to reach. And I already have a small Cap.... .5. My subs handle 600 RMS total. WOuld getting a bigger Cap help?: next time state year/make/model/mileage. most egr valves operate via vacuum. your subs can't affect a vacuum operated egr valve. if the o2 sensor didn't help out, you probably have a bad vacuum hose somewhere. that will cause the system to go into havoc because the car computer can't compensate for the excessive air being sucked in. a cap does not help with anything except for a loud THUMP. the THUMP causes a voltage spike and stresses the charging system. the cap takes care of the thump safer, it's not a complete solution.

Q: Hey, ive got a scooby and have a baileys dump valve that is a loud deep wooooosh sorta sound. What dump valve does the more high pitch sound? also they dump valve with the higher pitch seems to need less presure ta dump, mine needs alot of pressure before it will dump loud?: if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
