Using the correct torque specifications when adjusting camshaft timing is extremely important to prevent damage to the engine and ensure that the timing remains properly aligned. Over-tightening bolts can damage the threads and cause components to fail, while under-tightening bolts can allow the timing to slip out of alignment.

Always consult the vehicle’s repair manual for the correct torque specifications and use a calibrated torque wrench to tighten the bolts. Double-checking the torque specifications and tightening the bolts in the correct sequence can help ensure that the timing remains properly aligned and the engine operates safely and efficiently.
