Rushed rebuilds almost cost us a customer yesterday
My buddy skipped the final torque sequence on a head gasket job to save time. The engine started leaking coolant on the test drive. Always follow the manual, even when you're behind.
Actually, that final torque sequence lets the gasket settle RIGHT. It's not just about being behind on time. People forget it ensures even pressure across the whole head. Skipping it to save a few minutes is a HUGE risk, no matter the schedule. The manual has those steps for a solid reason, and ignoring them invites trouble.
