Engine replacement vs head gasket repair cost

A blown head gasket can cost around $1,500 to fix, but severe overheating damage may require a full engine swap jumping the bill closer to $5,000. Deciding between the two depends on whether the underlying block is warped or damaged, forcing car owners to weigh a costly repair against a total replacement before committing funds.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    running a borescope inspection
  2. 2
    checking for combustion gases in the coolant
  3. 3
    Replacing supporting components like the radiator and fans first to see if the engine still runs before committing to a full engine rebuild.

So at this point, engine swap, or HG replacement?source ↗

I just want to go in eyes wide open. With what I shared, what percentage is it that the engine needs repair in addition to radiator. That will move it from $1500 repair to almost $5k repair so I need to make a decision now.source ↗
