My engine harness has some damage from the egr pipe. The insulation is burnt and there are a few exposed wires. No malfunctions that I am aware of pre-teardown but still concerning. Since I have the engine out already for my now long slow rebuild (now in year 3), does it make sense to just replace it instead of trying to repair? I'm thinking yes, but at $500 for the part I would like some reassurance. Thoughts???
