I have just replaced the intake gaskets on a 2000 Blazer 4.3L. I have lost the distributer setting so now need to re-install as if new. There are 2 marks on the harmonic balancer. Oneat 12 oclock and oneat 3 oclock, looking from the front. Which is the correct one to set the timing.

Or the newly created EDI Engine Timing How-To.

 

Excellent. That is exactly what I wanted.

Thanks....John

 

It worked beautifully. Set the distributor where it was supposed to be and the vehicle started up at the first turn of the key.

Thanks for the help.

 

I have done nothing other than stated above but a contributer on another site tells me that I need to now have the camshaft retard reset with a scanner tool. Is this necessary. I have not driven the vehicle yet only run the engine since I have a couple of other things to attend to.
