Piston: Testing and Inspection

PISTON PROTRUSION





- Piston protrusion above TDC must be measured whenever new pistons, rods or a short block is installed.
- Depending upon the piston protrusion above TDC, install the correct gasket using the following table:

Piston protrusion: 0.91 mm to 1.00 mm
Use gasket with: 1 Holes/notches

Piston protrusion: 1.01 mm to 1.10 mm
Use gasket with: 2 Holes/notches

Piston protrusion: 1.11 mm to 1.20 mm
Use gasket with: 3 Holes/notches





- Cylinder head gasket identification:
- Part number = black arrow
- Holes/notches = white arrow

NOTE: If differing results are obtained when measuring piston protrusion, use the largest measurement to select the correct gasket.
