Teflon tapes should generally not be used in automotive engines. While Teflon tapes are resistant to heat and chemicals, they are primarily designed for plumbing applications and may not withstand the high temperatures and pressures inside an automotive engine. Additionally, Teflon tapes can leave residue or particles that could potentially cause damage to engine components.
For automotive applications, it is crucial to use proper gaskets and sealants specifically designed for high-temperature and high-pressure environments. These gaskets and sealants are formulated to provide a reliable and effective seal, ensuring the proper functioning of the engine and preventing leaks or damage.
