Since the beginning of hot rodding, gearheads have endeavored to increase the performance of internal combustion engines through the optimization of valve timing. It's been proven time after time that ...

There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

The VVT system operates by advancing and retarding the cam timing to suit the speed and load of the engine. Generally speaking, advancing the cam (from 0) tends to improve low-speed power, while ...

Decades ago (OK, half a century or more), there was a product advertised in many of the performance magazines called the Varicam. The idea was a set of springs attached to a centrifugal device that ...

What P0022 means: Indicates Bank 2 intake camshaft is lagging behind commanded timing, typically in engines with VVT systems. Likely culprits: Low or degraded oil, clogged or faulty VVT solenoids, ...
