after following the procedure in Haynes manual 25026 page 2A-7 I cannot seem to get the markings to line up like the manual says. I found top dead center on no. 1 cylinder, then turned crankshaft until the mark on the crank sproket lines up with the mark on the oil pump. The two cam sprockets seem to be 180 degrees off. I tried twice and got the same thing twice. The car was running okay when I took it apart but the engine would get noisy and sound like a sewing machine after about ten minutes. The sprocket markings or timing chain colored links do not line up. Have you got any info about this?
