I know that top dead center refers to piston number 1- ie the first cylinder on the PASSENGERs side. I have to remove my DRIVERS side cylinder head due to a head gasket leak. Is there any way that I could determine top dead center from one of the Driver's side pistons. Or example one of the cylinders in 90 degrees off number one then I could bring that piston to TDC and mark it out on the balancer and calulate No. 1 from there. Any suggestions on this. I hope my question makes sense, it seems easier that the other ways of finding TDC. Thanks.
