Internal combustion engines are nothing more than giant air pumps. How much power your vehicle produces is based on how efficiently it can suck air in and push it out. Your valve train plays an integral part in regulating the flow of gases in and out of your motor. If your valve train is damaged it can cause all sorts of problems including high oil consumption, poor running, power loss, and catastrophic engine failure. Here at Andy's Auto Sport we have a great catalog of valve train components from many of the leading brands. So weather you want to just replace a few seals or rebuild the entire valve train, you can find all the parts you need in our expansive lineup.
The term valve train generally refers to the piece of your motor that control the operation of the valves including rocker arms, valve springs, valve stem seals, pushrods, and the intake/exhaust valves themselves. These components are all crucial to the function of your motor, and they are also a great place to gain a little extra power with the right upgrades. Larger valves, stronger valve springs and high-ratio rocker arms can all significantly improve air flow, and thus make more power. If you are at a point where you need to rebuild your valve train, we think it is a good time to consider upgrading for a little boost in horsepower.
Q: What are valves? Why buy valves?
A: Valves are used to let a mixture of air and fuel into a cylinder and allow exhaust gases to get out. Each cylinder has at least two valves each, multi-valve engines have more, often four per cylinder. Upgraded head valves are able to withstand more heat from nitrous oxide use and turbo/supercharger use, so it's an excellent upgrade for people looking for added compression without sacrificing any reliability.

Q: How do you install valves?
A: Valves require headwork and should be left to the pros. While replacing valves, valve guides, retainers, valve springs and camshafts should all be considered for upgrades at the same time.
