Bringing this thread back to LIFE!
Did the timing belt, have vibration/noise at 2600 rpm. Definitely not as it was. So, either the front, back, or both of the balance shafts are off.
That is with the belt on or off?...
Also, any tips on special tool MDwhatever to set the timing belt tensioner pully (i call it the smilie face pully lol) and special tool MDwhateverelse to press on the hydraulic tensioner arm?

If you cant stick your screwdriver in the cylinder block plug hole as far as you need to (~60mm) and your oil pump gear lines up with its reference marks (like mine did), then you need to rotate the crankshaft clockwise until you encounter TDC again.

for the tensioner, just use a C clamp, and press it very slowly, and then pin in it...
for the smiley face pulley, use an allen key, and a precision screwdriver...or two allen keys, whatever, but use them so you can get some leverage, you know what i mean?
here's a picture i drew in paint:
Hope that helps...
It does sound like the forward balance shaft is out...the rear balance shaft, if the timing marks line up, it's good, though on the balancer sprocket it's going to end up slightly ahead of the mark in reference to a clockwise direction.
to check the forward shaft, yes, belt stays on, turn the crank by hand until all the marks are line up again, and do the screwdriver trick...if you need a picture of where the inpection bolt is to do this, send me a PM, do you have the service manual?
if the balance shaft is not aligned correctly, the belt need to come off...sorry

we used two allen keys, they bent... then used two drill bits and they stayed a bit better. Maybe we're just putting too much torque on the pulley when we're tightening the belt.
Found it rather difficult to get the tensioner pulley so that the pin easily moves in and out.

if the bolt on the pulley is loose it should not require a lot of torque, the manual shows the final position of the pulley, it should not require a substantial amount of force to put it there, and then you just tighten the bolt...
you leave the pin in the auto tensioner until the timing is aligned correctly, then pulling the pin is the last thing you do before installing the timing cover...i hope we're on the same page here, your last post was kind of confusing...

yes, that's exactly what i just said...if it were rotating clockwise, the mark on the sprocket would end up slighty ahead (before) of the mark on the block
see above...when i say ahead, i mean before, or in advance...the mark in the block is not in motion, so it's acceptable english to say the mark on the sprocket is ahead, no?
made sense to me, but you both said the same thing i was trying to say in different ways...

All done, was the front shaft, was out by 180 degrees.
I'm not really sure at all about the rear balance shaft. The way I see it, when everything is on the timing mark, the rear balance shaft is almost right on the mark, maybe just ever so slightly passed it. When setting it back a tooth, its noticeably before the timing mark, which is how I left it.
So far though, so good.

The back one, just line up the timing marks. You can check it, but you need to remove various pulleys and covers to get to the timing belt. The belt for the rear balance shaft is behind the timing belt.
