An engine block plays a major role on how vehicles work. Although it is made from highly durable materials, it is still not free from holes and cracks. Exposure to rust, changing weather and extreme temperature are just some of the many factors that can cause such damages. There is really no need to panic because it is very easy to learn how to repair cracked engine blocks.
Materials Needed
It only takes a few materials before anyone can go on and proceed in learning how to repair cracked engine blocks. Having a drill bit, torque wrench or hammer can make the job easier. Likewise, it is also necessary to have a J&B block seal, sodium silicate and metal stitching at hand when doing this thing.
Steps
Once the materials are set, it is now time to move on to the actual repairing process. Welding is one of the most popular techniques that people use to treat cracks in metal. However, this is not the case for engine blocks. According to auto mechanics, the use of welding can further aggravate the damage. This may be all right for engine holes but definitely not for cracks.
Instead of using welding to treat cracks, why not try metal locking? Also known as metal stitching, this procedure is probably one of the most effective ways of treating cracks. There are numerous kinds of metal stitching kits available out there. Buy one that is proven fast and effective against such damages. A regular kit must include all the right items to produce good and high quality results.
The basic idea is to put a stitch right along the crack to fix it. This is where the drill bit can be of great help. If there is none available, you can instead use either a torque wrench or a hammer. Both of these can actually get the job done. There are metal stitching kits that contain shoulders. This is a good thing because the stitch can actually go deeper. Because of this, the threads are not seen from the surface. This kind of thing can make the repaired part look very natural.
Additional Tips and Other Relevant Information
Always determine first the kind of material to fix. Buy the right metal kits for the appropriate material such as cast iron, steel or aluminum. When doing this task, do not rush things. Work on it slowly but surely in order not to cause further damage to the engine block. Before using metal stitching kits, check the instructions first to ensure a positive result. When you are not sure about what you are about to do, stop working and consult the help of professionals.
