I have done all the work to replace the valve head gasket and am putting my engine back together. With the head remounted, I am to the point of reinstalling the timing chain.
I am unsure which mark on the E Cam Sprocket is the timing mark. Can anyone explain the marks on this sprocket? I'll attach a pic of the sprocket for reference.

Thanks!

Thanks for the attempt, REACTOR. I understand HOW to install these cams, but the exhaust cam has three marks, two could easily be the timing mark. . .looking for clarification on which mark to use.

 

It's the one that's lined up with the locating pin. Wanna attempt to look at them manual pics again?

 

Still confused. Exhaust Cam sprocket has, moving clockwise from first mark referenced; E, *, *, l, l. As for locating pins, I cant find any type "pin" on sprocket and cam is installed so any pin on cam shaft is concealed. Should I remove cams to see the locating pin and timing mark before installing?The manual pics . . .I find no assurances for orienation ATDC 20 degrees.

 

 

Had to remove the nut. washer. . .maybe previos owner used larger washer. Thanks for your help. Got timing chain on and set!
