The torque spec for connecting rod cap is an important factor to consider when replacing or reassembling any engine. The correct torque specification can make the difference between a good and bad connection, as too little or too much torque on the bolts can cause problems like loose connections, bolt breakage, head gasket leaks and even engine failure. A general rule of thumb is to use a torque wrench with a range of 80-100 ft./lbs., although this may vary depending on your vehicle's model and year. Additionally, it's best practice to apply grease to all threads prior to assembly in order to prevent galling that could lead to eventual failure over time due to vibration. Furthermore, using Loctite thread locker will help ensure that the bolts remain tight throughout their lifespan. Following these tips should ensure that you have properly torqued your connecting rod caps so they are securely fastened within the block for years of reliable operation!
