2018 Civic Si Head Gasket Replacement
Budget: $250 – $750 USD
My 2018 Honda Civic Si refuses to start. The battery has finally given up, and a prior shop confirmed that the real culprit is a blown head gasket. They already ran diagnostics and pinpointed persistent overheating as the key issue, so I’m not guessing—I simply need the gasket replaced (and the battery swapped while you’re in there).
Here’s what I expect:
• Remove and replace the head gasket with an OEM-grade part, re-torque to spec, and reassemble.
• Flush and refill coolant and engine oil, clearing any contamination from the overheating episode.
• Install a new battery I’ll supply, then verify the engine turns over and idles cleanly.
• Run a post-repair check—coolant temp, idle stability, and a quick compression test—to show the problem is resolved.
The car is on my driveway with tools and space ready; you bring the expertise and specialty tools (torque wrench, coolant vacuum filler, etc.). Please outline how soon you can get here, how long the job will take, and any warranty you offer on workmanship.
