When theres a small opening at the end, it will increase carbon buildup rate as funnel effect. Some examples of the abnormal conditions are as follows. The product can wear out faster under certain conditions. Excessive buildup of carbon will also hinder performance and increase wear rate.
The Phosphor Bronze material has exceptionally lower friction and the best possible clearances can be maintained, which will reduce stress on valve train assembly, prevent seizures cracking under high loads. Then carbon can enter the valve guides more which will increase wear rate. This will cause both ends to open up and create deformation. We chose to use Phosphor Bronze CNN-Sn-P alloy make our Valve Guides, for its highly tensile and superior heat transferring ability, which is vital in high power RPM outputting engines.
The results from Valve Spring surging will cause the to move on an angle. These conditions will increase the deterioration rate on these valve train related components. For listings with free shipping, it only applies within the continental 48 states.
