2004 150 w/triton engine did cam phasors chains everything else over a year ago. This week the passenger side chain broke so i'm trying to figure out how to to set the timing for sure. I put crank shaft at 12:00 looked through #1 spark plugg seemed to be at TDC, drive side chain was about 5 links off the colored link so i think it was still good not sure but looked like cam lobes were inbetween on pass. side so set chain up any help would be good before i put this think back together.
