Is anyone out there replacing the crank bolt when they remove it for timing cover service/rebuilds?
Personally I would have never thought about it being a stretch bolt but according to the Bentley E36 3 series manual it is. Pg 117-6.
Crankshaft bolt. M16 stretch bolt. (Always Replace) Torque to 244 ft-lbs.
The bolt itself only appears to be around $10. Might just replace them on the 2 M42's I am building right now.
Anyone else aware of this?
