How To Repair an Engine Block Crack

It is a common fact that the engine is the heart of any motorized vehicle. It is what makes the motion of any vehicle possible. This is why if you love your car, it is important that your engine is always fined tuned and in optimal condition. Unfortunately, not even the most meticulous maintenance and care methods can prevent certain unforeseen damages from happening. Take the cracking of the engine block. No matter what you measures you do to prevent it, it can still happen to you due to many unforeseen factors. And, when it does happen, it is up to you to remedy the situation. Remember that the engine block is sealed tightly for a reason. It is so that no air or any outside particles can enter and contaminate the moving parts in the engine, particularly the pistons going up and down. A crack in the block will only lead to total deterioration of the engine should you keep running it without sealing that crack first. Obviously, you do not know the first thing on how to repair the crack in the engine block, which is why you are actually reading this article now. Well, today, you will be privy to some pointers on how to proceed with the repair and resealing of a crack in the engine block.

  • Don’t think you can do it on your own. Unless you are an experienced and certified mechanic, you should not even tinker with the idea of repairing the cracks on your own. The engine is a critical part of your vehicle and only trained hands should effect the repairs needed. If you force the issue, you are actually risking a lot since more serious complications to the engine may occur because of your haphazard handling of the situation. That said once you feel that something is wrong with your engine or if you see oil leaks all around the block, know that your best option is to bring it to the shop, one that deals expertly with engines.
  • Let the mechanic inspect the block. Alright, assuming that your car is now in the shop, the next step will be to get the mechanic to inspect and locate the cracks. Now, this can be difficult as the cracks can be quite minute and invisible to the naked eye. Your or the mechanic will have to clean up the particular area where the crack is suspected to be. Once clean, the mechanic will run a UV light on the area in order to see the cracks.
  • Once a crack is found, the mechanic will now have to determine if it can be repaired. Bear in mind that if the crack is too severe or if it located in certain places on the block, it may be irreparable. Furthermore, if the actual block is made of casted material, know that it is almost impossible to remedy the crack. On the other hand, if the engine block is made of steel or aluminum, the former will always cost much more.
  • Know the methods of repair. Technically, there are only two methods of repairing a crack, if it is at all reparable. The first is to weld it shut using the same material used for the block. The other option is to weld a sleeve over the crack. However, this is normally reserved for cracks located in cylindrical parts of the block. Either way, once the repairs have taken effect, a thorough session of testing and observation will be required in order to see if the repairs were able to plug the hole.

The costs for this type of repair will vary depending on severity and the material of your block. In most cases, it may be mandatory for the mechanic to open up the block and clean out the internal areas of the block to ensure that all the unwanted particles that may cause unnecessary friction are removed. You can surely expect to dole out more cash if that is necessary for the repair.
