(i) Measure the Plastigage at its widest point. Standard oil clearance: 1ZZ-FE:

0.028 - 0.052 mm (0.0011 - 0.0020 in.) Maximum oil clearance; 0.08 mm (0.0031 in.)

H the oil clearance is greater than maximum, replace the bearings. If necessary, grind or replace the crankshaft.




If replacing a bearing, replace it with one having the same number as marked on the connecting rod. There are 3 sizes of standard bearings, marked T, "2" and "3" accordingly. Reference
