how can i tell if my motor is at tdc and how do i go about getting it there if it isn't?

what motor? My z6 is at tdc when the middle white mark on the crank pulley lines up with the pointer on the timing belt cover. You can pull the #1 plug out too and put something in there to see when the piston is all the way up.

i assume this i tdc for cyl #1?

it's a y8..i have anew cap, rotor i need to put on, laong with some other stuff, but i've heard it has to be at tdc to do it?

 

[singlecizam]

it does not have to be at TDC, the rotor can only go on in 1 position.. change 1 wire at a time so that you dont mix up the firing order

 

[1990reds13]

what about the cap though? would you say just to put it on in the same plcae as the old one?

 

[singlecizam]

it will only go on 1 way also

 

[1990reds13]

oh, so i can basically just take a picture of the rotor, then put the old one on in the same position then change the wires one at a time?

yeah, the rotor should have a flat spot that matches the flat spot on the dizzy. It is like this so that you cant put it on wrong.
