Disassembling a Subaru WRX Engine Exposes Risks of Improper Rebuilding



Choosing the right mechanic is crucial when it comes to car ownership, as poor repairs can lead to costly consequences. In a recent video on the I Do Cars YouTube channel, Eric got his hands on a Subaru WRX engine with plans to dismantle it for parts and scrap metal. Upon draining the oil, a significant amount of metal shavings were discovered, indicating serious internal damage. The inspection of the engine revealed metal shavings in various areas, including the heads and timing chain, causing scoring on the camshafts and spreading throughout the engine. This damage was likely the result of metal entering the oiling system and scraping delicate moving parts.

Further examination of the engine revealed signs of previous repair work, with a subpar head resurfacing job and an aftermarket turbocharger. Removing the oil pan exposed even more metal shavings, along with a large piece of a piston ring. Surprisingly, none of the pistons were missing rings, indicating that this piece must have been left behind during a previous repair and not properly cleaned out. As the pistons were removed from the crankshaft, the main cause of the damage was discovered – a spun rod bearing that had disintegrated and likely led to a loud knocking sound from the engine.

This video serves as a cautionary tale for car owners to do thorough research before choosing a mechanic. It is essential to find a reputable and skilled mechanic to avoid the costly consequences of poor repairs, as seen in the case of this damaged WRX engine. Taking the time to research and choose a reliable mechanic can save car owners thousands of dollars in the long run by ensuring that repairs are done correctly the first time. Trusting your vehicle to a qualified professional can prevent the type of damage and neglect that was uncovered in this engine.

In addition to selecting a reputable mechanic, it is important for car owners to stay informed and involved in the repair process. By understanding the basics of car maintenance and repair, owners can better communicate with their mechanic and ensure that work is done correctly. Regular maintenance and inspections can help prevent major issues like the ones that were discovered in the WRX engine, saving both time and money in the long term. Owners should also be proactive in addressing any unusual sounds or performance issues with their vehicle to prevent further damage.

When choosing a mechanic, car owners should look for certifications and experience in working with their specific make and model of vehicle. Reading reviews and getting recommendations from friends or family members can also help identify trustworthy mechanics in your area. Communication is key when working with a mechanic, so be sure to clearly explain any concerns or issues you have with your vehicle. Establishing a good rapport with your mechanic can help build trust and ensure that your vehicle receives the best possible care.

In conclusion, choosing the right mechanic is essential for car owners to avoid costly repairs and prevent serious damage to their vehicles. By doing thorough research, staying informed, and communicating effectively with your mechanic, you can ensure that your car receives the proper care and maintenance it needs. Trusting your vehicle to a reputable and experienced mechanic will give you peace of mind and help keep your car running smoothly for years to come.
