The crankshaft timing mark should be at the 5 o clock position.

Intake cam timing mark should be at the 2 oclock position.

Exhaust cam timing mark should be at the 10 o clock position. Note that the timing chain has colored links that align with each of these marks.

the chain on the inside behind the timing chain. is that one need to be timed?
Expert:  Dave Nova replied 4 years ago.
This other chain drives the balance shaft. It must be timed correctly or the engine can vibrate badly when running.

Install the balance shaft drive chain with the colored links lined up on with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three colored links on the chain. Two links are of matching colors, and one link is of a unique color. Use the following procedure to line up the links with the sprockets:Orient the chain so that the colored links are visible.
3. Place the uniquely colored link (1) so that it lines up with the timing mark on the intake side balance shaft sprocket.
4. Working clockwise around the chain, place the first matching colored link (2) in line with the timing mark on the crankshaft drive sprocket. (approximately 6 o'clock position on the crank sprocket)
5. Place the chain (3) on the water pump drive sprocket. The alignment is not critical.
6. Align the last matching colored link (4) with the timing mark on the exhaust side balance shaft drive sprocket.

what are the torque spec's for the timing chain guides
Expert:  Dave Nova replied 4 years ago.
All of the chain guide bolts and tensioner bolts are torqued to 89 inch pounds (10 Nm)

This is 7.4 ft. lb. so not a lot of torque on these bolts.
