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.: Mazda 929 Specs

Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.: When talking about car engines, references such as v4, v6, v8, v10 and v12 are not for the number of valves. it is for the number of cylinders. The more cylinders that an engine has, the more fuel it consumes and most of the time, the more horsepower it can make. There are exceptions to this though. Regarding the noise of the engine, i would agree that a v8 sounds very good when it is roaring. Valves are actually the openings for fuel to get into the cylinders and the exhaust to come out from. Most modern engines have two valves for incoming fuel and two valves for the exhaust making a total of four valves per cylinder. hope that clears it for you
