opti spark
 

is it necessary to find TDC in order to change the opti spark? what will happen if TDC is not found before the removal of the opti spark??

Makes no difference. It only goes in one way, but you must make sure not to force it. There is a difference on how the vented and unvented key in. Get a repair manual to be sure.

what happens to the optical sensor when moister is present, other than not allowing to distingush the slotted? does the optical sensor burn??
