Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Measuring Oil Clearance
Check the oil clearance by measuring the outside diameter of the crankshaft journal as well as the inside diameter of the bearing. The clearance can be obtained by calculating the difference between the measured diameters.
