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.
Engine Block
- Clean the engine block thoroughly and check all core hole plugs for evidence of leaking and repair if necessary.
- Examine the engine block and cylinder bores for cracks or fractures.NOTE:
Check the engine block deck surface with a precision straightedge and feeler gauge. The surface irregularities should not exceed 0.09 mm (0.0035 in.). Check the deck surface from one end to the other with the precision straightedge positioned across corners and parallel to the block centerline up and down the deck.
- Check the engine block deck (1) surfaces for flatness using a precision straightedge (2) and feeler gauge (3).
