after my t belt install on my jdm d15b i put the cam gear at tdc then i was looking for the mark on the crank pully and all that was there was a little W engraved...my friend said it stand for witness mark which is what you line it up to....anyone heard this? i just dont want my motor to blow up soon as i get it started...TIA

On mine there was a pointer on the crankshaft, and then a mark on the oil pump to line it up to. Never heard of a witness mark.

put your crank pulley on and line it up at the white mark all by itself

no white mark thats my point

ABK

no marks on your crank pulley? at all nothing, not even notches

If not time to get a new pulley because I have no idea how you are going to time your car.

there should be 3 marks real close to each other looking something like this( ||| ), and then one single one by itself which is what you line up with the pointer on your plastic cover. this isnt on your crank pulley???

yeah im pretty sure its not all i see is a W...is it on the top of the crank pully or the flat surface thats parallel to the motor?

their is a white mark on the pulley, and there is an etch in the shaft itself if you take the pulley off. Either will work.

not sure about the W, but I'm with the guy above...

maybe we could get a picture of what you're seeing?

here just do this, put a screw driver or something really really long into a #1 spark plug hole and rotate it by hand do not crank it. And look for a place where the screw driver or whatever you put in there sticks up the most. That's your TDC.
