Great looking forum! I'm trying to find the torque specs for a 4AC valve cover. I bought a Toyota factory manual and can't find it.

Thanks

Rob

i don't think it matters too much, it's just the valve cover as long as it doesn't leak and you don't brake it

what does your toyota factory manual say about headbolts? does it say discard and use new ones?

Thanks for the reply. I cracked my initial valve cover by overtightening. I purchased another at a wrecking yard. Cleaned/installed. Started off at 10 ft/lbs, worked up to currently 13 ft/lbs. around two weeks w/ no leaks

they're really flimsy to be honest. i am putting a new head gasket and I am trying to figure out if the head bolts are one time use or not, does your factory manual say anything to enlighten me?

No. When it comes to the valve cover the shop manual isn't very helpful. The information may be in there but I'm not finding it easy to find. I re-use the nuts but replace the gasket and the gasketed washer,
