.....hi, according to the manual three stages starting off at 30 Nm then 60 Nm, finishing with 88 Nm. Do you have new head bolts and always start at the middle of the cylinder head working your way outwards towards either end.
Remember most head gasket failures are due to dirty surfaces or warped cylinder heads.
SOURCE: TOYOTA HILUX 2006 engine head torque specs
it depends on the size of the screws. i recommend to set torque as 100lbs for new bolts, 90 for old bolts
SOURCE: i need too know the torque specs on head bolts and crankcam 2.4 engine
on a 2002 2.4 engine head bolts are 'torqued to distance'.
First, install all the bolts, and, in a sequential fashion, starting at
the innermost, working outward, torque all bolts to 70 N-m/806 kgf-cm/58
foot lbs.
Next, mark the front side of each head bolt with a dot of paint.
Retighten the cylinder head bolts 90 degrees, starting at the inner 2,
and working outward.I dont thin anything has changed on this engine since then.
