Hello,

Below are the specifications for the M274/M270 engine
New cylinder head bolts, Harmonic balancer, crankshaft bearing and connecting rod bolts must be used
Only connecting rod bolts for 260 engine can be measured for maximum length and reused if within specification, maximum length of 38.4 mm

Hope this helps.

Cheers, Boris
