I'm doing my timing belt for the first time. I rented tools, and got a TB kit. Bentley repair manual says there's some sort of sealing plug on the left-side of cylinder block. Here's what the manual says/shows:

Turn crankshaft at central bolt of toothed belt gear in direction of engine rotation to cyl. 3 TDC. Timing marks -A- and -B- must be aligned.
Check position of camshafts. Large holes (arrow) of securing plates on camshaft sprockets must face toward inside and align.
If not, turn crankshaft one revolution further.
Remove sealing plug from left-side of cylinder block.
Top Dead Center (TDC) mark on crankshaft must be visible or be felt behind bore of removed sealing plug.
WARNING!


DO NOT turn crankshaft while checking for TDC mark. Personal injury may result.
Install 3242 crankshaft holder into sealing plug opening.
Remove tensioner for ribbed belt.
Remove center and right toothed belt guards.

found this writeup sooner. But I already finished everything, and it turned out SUPER! The engine sounds a lot more quiet after I replaced all the rollers and the water pump. Hope I won't have to go in there in the next 60k mi.
