when i was reinstalling the cam gear after doing a head gasket job the chain slipped on the bottom and the bottom end got turned over accidentally. How do I re time it properly and do i need to replace any extra parts? please
help!!!!

 

Timing a first gen Mini is super easy, take of the crank pulley, take off the timing case behind it and line the markings up on the crank and cam shafts. See pictures below for the marks.


Crank, notice the two arrows pointing to the colored chainlinks

Cam, notice the one arrow and one colored chain link
