Here is another new TS160 Enginetech upper cam sprocket:
Notice the timing dots in relation to that elogated hole ( hole one of 3 )
Pretty easy to see that the two upper cam sprockets have different timing dot locations, one tooth off. Even though they are the same part numbers from Engintech. View attachment 1715620845
This cam sprocket above has the timing dot in the correct location. ^^^^^
I will take a pick of the sprocket side by side with the other one in the morning so we can see the location relative to another brand. You can really see it when they are on top of each other with the keys lined up. Like I pictured this morning.
