Checking piston protrusion with cylinder head removed (Range Rover 3)

1. The top surface of the cylinder block and the piston bottoms must be clean.



2. Secure the dial indicator to the LRT-12-181 stand and install it on the cylinder block.

3. Set the indicator to "zero".



4. Place the indicator on the piston crown and measure the piston protrusion at two points as shown in the figure. Rotate the crankshaft until the piston is at TDC. Record all measured piston protrusion values and repeat the procedure for all pistons.



5. The required thickness of the cylinder head gasket is determined by the greatest value of the piston protrusion.



6. If the piston protrusion is from 0.92 to 1.03 mm, then a gasket with two notches must be installed.

7. If the piston protrusion exceeds 1.03 mm, then a gasket with three notches must be installed.
