Q:Difference between Dump Valve and...?
The blow-off valve releases boost pressure into the atomsphere when decelerating to avoid compressor surge. The dump valve bleeds out compressed air produced by the inertional rotation of the turbo impeller into the atomsphere when the throttle valve is closed. The bypass valve does the same thing as the blowoff valve, except that it recirculates the compressed air back into the intake instead of out into the atomsphere. Diverter valve is just another name for blowoff valve.
Q:Another EGR valve question?
Bring it to the dealer, they will take it apart and find out whether it's just clogged or broken or something else - like for example, DPFE sensor on Fords
Q:valve tap that goes away?
Keep eye on oil level and keep on driveing.
Q:new EGR valve?
i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.
Q:Are valve stems replaceable from one tire to another tire?
Any reputable tire shop will install new valve stems when mounting new tires. This really sounds like somebody is messin with you. Anyone else in your area having similar problems?
Q:ERG valve needs cleaning?
You'll be fine, drive it.
Q:replacing valve cover gasket?
I would use Chevy orange heat resistant paint for the covers and as far as the gasket, when you do pull off the valve covers, you will have to clean the surfaces with a PLASTIC putty knife and maybe steel wool to smooth it out fine. DO NOT use anything metal on these surfaces as you might gouge it. Whatever you do, make sure you put rags over or inside the camshaft/valve assembly so you do not get any gasket pieces in the valves because you will have REAL problems then......Depending what kind of gasket (aftermarket) is made for your car, if it is cork, you will want to put gasket sealer on the gasket (Both Sides) first, and then place it on the surface and then put the cover on. Make sure that when you tighten the bolts, they should be torqued to specifications of your car. And if you go ahead and tighten them without a Torque Wrench, just make sure you criss-cross tighten, starting from the corners and working opposite and DO NOT over-tighten !!!!! I would strongly recommend that you torque them to whatever inch-pounds !!!!
Q:Mitral valve repair surgery?
From what i've got study having it repaired rather than replaced has a much greater helpful restoration consequence. The survival fee is in the mid ninety's % clever so curiously like an rather secure surgical operation. Hoping she has a rapid restoration.
Q:What is the importance of engine valves?
Most okorder.com, and check the service records for the car you are interested in buying.
Q:Wiring water Level Switch to Solenoid Valve?
considering your valve and turn is contained in the tank, why do no longer you in simple terms use a flow-activated valve and eliminate the electrical powered conclusion entirely? Why do you think of they use flow-valves in lavatories? because of the fact they do no longer consume any electrical energy and that they are undemanding units. considering you're no longer controlling a pump, why no longer in basic terms shop it undemanding?
