Cylinder Block Deck Flatness Inspection

Inspect

1. Ensure the engine block decks are clean and free of gasket material.
2. Inspect the surface for any imperfections or scratches that could inhibit correct cylinder head gasket sealing.
3. Place a straight-edge diagonally across the cylinder block deck face surface.
4. Measure the clearance between the straight-edge and the cylinder block deck face using a feeler gauge at 4 points along the straight-edge.
5. If the warpage is less than 0.05 mm, the cylinder block deck surface does not require resurfacing.
6. If the warpage is between 0.05 ± 0.20 mm or any imperfections or scratches that could inhibit correct cylinder head gasket sealing are present, the cylinder block deck surface requires resurfacing.
7. If resurfacing is required the maximum amount that can be removed is 0.25 mm.
8. If the cylinder block deck surface requires more than 0.25 mm material removal the block must be replaced.
