Alright, to start things off you need to remove the timing belt covers so you can see the tensioner and find out what the problem with that is.
You need the number one piston to be at TDC compression stroke (number one piston is the one on the distributor side)
Can't take my word on this next part because I've been working with the B18B1. The one white mark on the right side of the three is the one that needs to be lined up with the tab.
The cams might have a 5 mm hole right behind the gear to line them up. (B18B1 does)
