Removing damaged threads and tapping new ones
The process of removing damaged threads and tapping new ones involves several steps and requires some specialised tools. The first step is to identify the size and pitch of the damaged thread. This can be done using a thread pitch gauge or by matching the thread to a nut or bolt of a known size. Once the size and pitch of the thread have been determined, the correct tap can be selected. There are several types of taps available, including taper, plug, and bottoming taps. For repairing damaged threads, a taper or bottoming tap is usually the best choice.
With the correct tap selected, the next step is to lubricate the thread and tap with a suitable lubricant, such as WD-40 or cutting fluid. This will help to reduce friction and prevent the tap from becoming stuck in the hole. The tap should then be slowly and carefully inserted into the hole, ensuring that it is aligned correctly and does not become crooked. As the tap is inserted, it will cut new threads into the metal, repairing the damage. It is important to take your time during this step and to back the tap out occasionally to remove any debris and lubricate the tap.
Once the new threads have been cut, the hole should be cleaned out using compressed air, brake cleaner, or lubricant to remove any remaining debris. Finally, a new fastener can be installed, taking care not to over-tighten it and damage the threads again.
In some cases, it may be necessary to drill out the existing threads and tap the hole to accept a larger fastener. This is a common practice when dealing with cast iron and steel alloys, which have a higher hardness rating and greater thread strength. When a larger fastener is not an option, an insert can be installed to repair the damaged threads and allow the use of the original fastener size.
One popular type of insert is the HeliCoil, which is made from square, stainless-steel wire wound in a diamond profile that fits into the repair threads. HeliCoils require a specific type of tap known as a Screw Thread Insert (STI) tap, which is larger in diameter than a standard tap of the same designation. The hole is drilled and tapped to accept the HeliCoil insert, which is then screwed into place using an installation tool. Once the insert is in the correct position, a tang on the end of the insert is broken off to secure it in place.
Another option for repairing damaged threads is the TIME-SERT, which is a solid carbon steel or stainless-steel insert with synchronised inner and outer threads. TIME-SERTs also require an STI tap and a combination drill/counter-boring tool or a separate counterbore to create a flange that allows for precise positioning of the insert. The insert is then threaded into the hole using an installation tool, and a thread locker can be applied to the outer threads for additional strength.
A third type of insert is the Keensert, which is a thick-walled, solid-body insert with retaining keys. Keenserts use standard taps that are two steps larger than the original threaded hole, resulting in a larger hole and tap diameter compared to HeliCoils and TIME-SERTs. The insert is threaded into the drilled and tapped hole using an installation tool, and the retaining keys are then driven into position using the same tool, providing maximum resistance to vibration.

Using magnetic drain plugs
Magnetic drain plugs are an effective way to remove steel particles from your engine oil. They are cheap and easy to install, and can be purchased from a reputable brand or as a steel magnetic drain plug. When installing a magnetic drain plug, it is important to ensure that the thread pitch of the new plug matches the stock one.
Magnetic drain plugs work by attracting and collecting ferromagnetic crud, which can include normal wear particles shed off of things like your primary gear, transmission gears, and piston rings. This helps to keep your engine oil clean and free of debris, which can improve the performance and longevity of your engine.
Some people may question the need for magnetic drain plugs, as most engines have an oil filter that is already effective at removing particles. However, magnetic drain plugs can capture steel particles that are smaller than 30 microns, which is the average size of particles captured by oil filters. These small particles can be the most destructive, as they can fit into tight spaces in your engine and cause damage.
Additionally, magnetic drain plugs can provide an added layer of protection for your engine. Based on the sludge and gunk that can be wiped off of magnetic drain plugs, they seem to be effective at capturing and removing debris from engine oil.
Overall, magnetic drain plugs are a simple and inexpensive way to help maintain the health of your engine. They can capture and remove small, destructive steel particles that may not be captured by an oil filter alone. If you are considering adding a magnetic drain plug to your engine, be sure to purchase a quality product from a reputable brand and ensure that the thread pitch matches your stock plug.
