Frequently Asked Questions (FAQs)

1. Can spark plug threads be repaired?

Yes, spark plug threads can be repaired. If the threads are damaged or worn, it is possible to repair them instead of replacing the entire cylinder head. This can save time and money.

2. How much does it cost to rethread a spark plug hole?

The cost of rethreading a spark plug hole can vary depending on the shop and the extent of the damage. It can range from around $250 to $1,000. The final cost will also depend on whether the repair can be done with a helicoil or if additional work is required.

3. Can damaged threads be repaired?

Yes, damaged threads on a screw or bolt can often be repaired. Running a die over the damaged threads can help fix them. In some cases, it may be possible to reform the threads by running a nut up and down, but this carries the risk of galling or fusion.

4. Are spark plug threads universal?

No, spark plug threads are not universal. It is important to buy spark plugs that are specifically designed for your vehicle. Spark plugs come in different sizes, gaps, and are made from various metals. It is essential to use the correct spark plugs for optimal performance and compatibility.

5. What is the best lubricant for spark plug threads?

To prevent possible seizure and ensure smooth installation, it is recommended to use a lubricant like LOCTITE 767 (ANTISEIZE LUBRICANT) (P/N 293 800 070) on the spark plug threads. This lubricant helps to reduce friction and make future removal easier.
