This Bonbo kit is machined from aluminum to tight tolerances to mimic the balancer and pan locations, making it easier to install covers without stress or misalignment that can lead to leaks or fitment problems.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the tool help prevent seal leaks and misaligned covers?\u003c\/h3\u003e\n\u003cp\u003eThe alignment pieces center the cover bores relative to the crank flange and oil pan so the seal lip seats evenly.
