How do you time the intake cam at TDC?
If you are timing the engine or valve train and need more precision there is a small hole in the back of the cam sprocket. To time the cams at TDC install a small Allen key into the hole in the back of the sprocket and it will lie flat on the head by the cam journals (red arrow) when at TDC. The same procedure applies to the intake cam.

How is the M104 engine set at TDC?
The M104 engine is a contact motor, which means if the timing between the cams and pistons (via the crank) are off you will do serious if not terminal damage to the motor. The motor needs to make two full rotations to complete a cycle. This means the zeroes on the dampener can line up 180 degrees off of TDC.
How do you set the engine at TDC?
Just use care working around it. Turn the crank clockwise until the marks on the balance dampener (red arrow) line up at the mark between the two zeroes with the witness notch (yellow arrow) on the motor. The motor needs to make two full rotations to complete a cycle, which means the zeroes can line up 180 degrees off TDC.
