Need some help looking up the correct Time-Sert thread repair kit? See the lookup application chart below for our top Time-Sert sellers. If assistance is still needed, we will be happy to help. Contact us and provide the year, make, model and specific type of threads being repaired (ie headbolt threads, spark plug threads, oil pan threads, main bolt threads etc). Also, it's important to mention if the threads have been repaired previously. We have Big Sert kits which are over-sized that can be used in many instances.
