Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve: Assuming that the stop valves are good, turning them off will stop the flow of water to the sink taps. To test them, turn on the water faucet at the sink, then turn off both stop valves. The water should stop coming out of the faucet. If it continues to drip, the stop valves are defective and should be replaced when you do the job. If this is the case you'll have to shut off the main water valve or a valve upstream of the stops to replace them. Good Luck

Q: For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.: you do not torque valve covers down, buy a new gasket , I would get a good quality rubber one and some blue rtv sealer, clean any crap off the valve cover no glue no bits of gasket nothing, same thing on the head surface, glue the gasket on the valve cover, let it set, then carefully put it on, start with the bolts in the middle and work out finger tight all of them, then just snug the bolts down, dont crush the gasket, you can also use a light duty locktite to hold them in place, and often times old valve covers are warped, it is too your advantage to make sure its as flat as you can get it, or spend a few bucks a buy a new one. your choice, but snug the nuts down good with out crushing and bending the thin sheet metal of the valve cover.

Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one.

I Have an 86 Rx7 and when I test the EGR valve is doesn t hold pressure. So I m curios are they different from other vehicle due to is a rotary engine or due they all work the same. Thank You.

Q: i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II: well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..
