SOURCE: bolt torque specs
I have used Haynes service manuals for (hate to admit it) many decades and I recommend you check to see if this one:
http://www.amazon.com/Haynes-Toyota-Automotive-Repair-Manual/dp/1563923513
doesn't cover your engine.
I have found darned few 'holes' in their coverage.
Auto parts stores carry these and I suspect that even though sealed, the sales people will not give you too hard of a time if you explain you want to insure you are getting what you need.
Haynes is not the same as it was 20 years ago before they were acquired by Chilton but the price/utility ratio is still pretty good.
Mostly I'm annoyed by the move to cheaper paper (newsprint)that is fussier, picks up dirt, tears more easily than the better paper of yore.

hey, torque must be done in 3 steps:
1st 22 ft lbs
2nd 43 ft lbs
final 47 ft lbs
use this sequence of tightening:
9 - 3 -1 -6 -8
7 - 5 - 2 -4 - 10

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.
