Deck Flatness Inspection
WARNING: This page is about a different variant/trim than selected.
- Ensure the engine block decks are clean and free of gasket material.
- Inspect the surface for any imperfections or scratches that could inhibit proper cylinder head gasket sealing.
- Place a straight-edge diagonally across the cylinder block deck face surface.
- Measure the clearance between the straight-edge and the cylinder block deck face using a feeler gage at 4 points along the straight-edge.
- If the warpage is less than 0.05 mm (0.002 in), the cylinder block deck surface does not require resurfacing.
- If the warpage is between 0.05-0.20 mm (0.002-0.008 in) or any imperfections or scratches that could inhibit proper cylinder head gasket sealing are present, the cylinder block deck surface requires resurfacing.
- If resurfacing is required the maximum amount that can be removed is 0.25 mm (0.010 in).
- If the cylinder block deck surface requires more than 0.25 mm (0.010 in) material removal the block must be replaced.
