A common issue on N54 motors is cam bearing ledges scoring due to lack of lubrication, and if left unattended can cause damage to the camshafts and increase oil consumption. These WPC-treated cam bearing ledges help prevent lubrication issues to ensure no scoring occurs on the bearing ledge or camshaft. What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both.

Rocker arms work in conjunction with your camshafts and valves, applying pressure from the camshaft to open and close your intake and exhaust valves. If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced. Replace your rockers whenever servicing your camshafts or replacing your hydraulic lifters to ensure long-term engine reliability.
