For vehicles with turbochargers, the oil feed pipe, which supplies oil to the turbocharger, does not have sufficient rust-proofing structure and waterproofing structure, and therefore, if repeatedly driving on a road to which a snow-melting agent has been applied, water may land on the pipe and cause rust. If this problem is left unattended, a hole may be formed in the pipe, which will cause an oil leak, and in the worst case, the oil could deposit on the catalytic converter and ignite, and the fire could spread to the engine parts.
