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. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
HI i have question is all EGR valve work the same ? 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.

D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel
Q: Butterfly valve, two-way pressure and one-way pressure what is the difference?
One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. Two way butterfly valve is butterfly plate can face or back to the media flow direction, installation without attention to medium flow direction, in the valve body also does not indicate the direction of the medium flow arrow. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter.
Q: My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve.
