When it comes to deciding whether replacing a head gasket is cheaper than replacing an engine, the answer can depend on a variety of factors. Replacing a head gasket will usually be less expensive than replacing an entire engine because the parts and labor costs are significantly lower. However, if your car has suffered extensive damage due to overheating or other issues, then repairing the engine may be more cost-effective in the long run. Additionally, some engines require specialized tools which can add to the cost of repairs. If you’re not sure what type of repair is best for your vehicle and budget, it’s always best to consult with a certified mechanic who can provide advice on what course of action would make financial sense for your situation.
