My top balance shaft pully is a little off the mark, but if I move it one tooth over, it's even farther off the mark to the other side. The bottom one is ok, and the engine is at TDC. Is this ok? I think I remember reading somewhere that it was normal to be a little toward the 1 0'clock position, but I want to check with the experts.

 

I am curious if you feel any vibration?

My balance shaft alignment was similar

I do feel a little, and it's gotten worse over time, but i think that might be the motor mounts too. I gotta check them. I don't know how long they're supposed to last, but mine have been 20k miles. I also might change the 02 sensor as i don't know if its ever been replaced and that might give it a little rough idle.

 

If your vibration is evident over 2,000 RPM and gets worse at the higher ranges you are off on the balance sprocket; motor mounts really only cause problems low down, esp at idle. The mark is on the guard so it is not the most precise thing in the entire world.
