4 FAQs About A Head Gasket Repair
Let’s get some answers to queries on head gasket repairs:
1. How Often Does A Head Gasket Need Replacement?
There’s no specific timeframe for head gasket failure. But with proper engine oil and coolant maintenance, and an engine that runs at optimal temperatures, head gaskets can generally last at least 100,000 miles.
2. Will A Head Gasket Repair Fluid Or Sealer Work?
The answer depends on how the head gasket fails.
If a head gasket leak turns up after your engine overheated, then a liquid sealer won’t work. If the engine didn’t overheat and the leak is between the cooling system and combustion chamber, then there’s a chance the repair fluid can work.
The important thing to remember is that this type of fix is not permanent.
3. Is Fixing A Blown Head Gasket Worth It?
Because the head gasket repair cost can sometimes be restrictive, there will be situations where a head gasket replacement might not be worth the trouble, like:
- You have an old car and were planning on getting a new one
- The head gasket repair cost is excessive, either due to premium parts needed or intensive labor charges
So, while getting a head gasket repair is crucial, there may be circumstances where alternatives like replacing the engine, or even purchasing a new vehicle might be more worthwhile in the long term.
4. How Is A Head Gasket Replaced?
A head gasket replacement is a complicated and tedious process, which is why it’s not recommended as a DIY.
Here’s a simple overview of what a mechanic would have to do:
- Drain all the coolant and oil from the engine.
- Take out a substantial portion of the engine to access and remove the damaged head gasket. This includes the camshafts and cylinder heads.
- Clean up all bolt holes and the engine block surface.
- Put in a new head gasket, then reinstall the cylinder heads, camshafts, and all other engine pieces that had been disassembled.
- Set the timing gears and camshafts to the vehicle’s precise orientation, ensuring smooth engine operation.
