OHC experts. caddy northstar
i am setting the timing on a caddy northstar motor. i know the cams turn at 1/2 the speed of the crank. crank turns 360, cam turns 180. there is also an intermediate sprocket that is larger than the crank sprocket. i know why the crank timing mark has to be at 12 oclock. that indicates TDC for #1 cyl. than the cam dots are lined up at 12 oclock to the head surface. why does the manual even mention that the inter sprocket needs to be at 6 oclock? it could actually be pointing anywhere as long as the crank is at 12oclock.
