Hi...

 

Just to confirm as to your question..

 

Is this a 116i . 118d . 118i ?

 

Also these engines do require timing locking pins/tools as they essentially don't have marks for lining up...Do you still need the set up and diagram anyway?

 

Customer: replied 4 years ago.
it is a 116 & please send diagram & info
