Timing chain jumps

[NeilTM]

Where people have reported incidents of  timing chain jump, on any vehicle, whether at start up, or after cranking an engine, or during clutch replacement, has anyone recorded which direction the jump occurred in?  Did it leave the timing advanced or retarded?

 

Please be clear about the precise circumstance in which the jump occurred if able to report whether the timing became advanced or retarded.

 

Thank you.
