2E head torquing tightening sequence, how does it go?

Postby Helious » Tue Jan 29, 2008 6:48 pm

Old man is wanting to know what sequence the head bolts should be torqued and tightened in.

I already know this

The 2E settings are :
Inlets - 0.20mm (0.008 thou)
Exhausts - 0.20mm (0.008 thou)
Clearances should be set when engine is HOT.

Head Bolt Torque:
Stage 1 - 22 ft-lb
Stage 2 - 36 ft-lb
Stage 3 - Put a dot of white paint on the head bolts at the 12 o'clock position and then turn the bolts 90 Degrees in a diagonal sequence.
The dots of paint will then be in the 3 o'clock position.




He's just wondering what sequence they should be tightened in.

Thanks in advance

Start at the middle and work your way out. Do the middle 2, then one on the left, one diagonally opposite on the right and then the 2 you haven't done, then do the same thing for the next ones out etc.

No point mucking around with the dot, its pretty obvious where 90° is when you put a bar on it and tighten them quarter of a turn

Pretty much what I was trying to say without actually drawing it or putting the effort in to find a pic :lol:

Yeah, Old man knew what you were talking about, it's what he thought himself...

Personally, for a layman like myself I thought the diagram was a nice touch.
