Crankshaft Bearing Clearance, Check (Determine Bearing Clearance with Plastigage)  

  Remove, Disconnect   

Remove crankshaft bearing cap from cylinder block - mark installation position.     Measure    Using Plastigage (Plastigage is available via the "Opel/Vauxhall Workshop Equipment" catalogue).   Plastigage is available for two measuring ranges.     Important!    To prevent the thread from tearing when removing the con-rod bearing cap, remove grease from the con-rod journal and lightly oil con-rod bearing shell.   Do not turn crankshaft!

  Measure   

Cut Plastigage to width of bearing and lay axially between con-rod journal and bearing shell (arrow).     Torque - Angle Method    Crankshaft bearing cap to cylinder block - tightening torque   50 Nm/37 lbf. ft. + 45 ° +15 ° .   The bolts can be reused for checking the crankshaft bearing play.     Measure    Remove crankshaft bearing cap again. Compare width of the flattened plastic thread with the measuring scale.   Permissible crankshaft bearing clearance:   1.4 / 1.6 ltr. engines except 16 LZ2   0.015 to 0.041 mm   1.8 / 2.0 Ltr. Engine and 16 LZ2:   0.015 to 0.043 mm

  Install, Connect   

Clean crankshaft journal and crankshaft bearing shell and lubricate slightly.  

Install crankshaft bearing cap at cylinder block - note installation position.  

  Torque - Angle Method   

Attach crankshaft bearing cap to cylinder block with new bolts - 50 Nm/37 lbf. ft. + 45 ° + 15 ° .
