Just wanting to know the pressure setting for use of a torque wrench and socket sizes for a 4Litre please, needed for the following items;

Head Bolts

Rocker Bolts(lots of them and small)

Exhaust Manifold

Intake Manifold to intake port

and is AU Headgasket better to put on eb as i was told they are made out of metal and eb's do head gaskets alot?

Cheers Sean

Hi if you buy a new head gasket kit it should have the settings on the packet you need and yes buy a AU head Gasket its better
Cheers Alan

rocker arm bolts 20nm to be safe, as the factory 25nm setting has been known to be a bit much for old bolts

Head: 40 NM + 90 degrees, but I think its different for AU gaskets.
Rocker bolts: 25NM according to factory
Exhaust: 30 NM
Intake: 25NM

Rocker rack bolts 10mm
Head bolts 14mm *IMPACT SOCKET ONLY* ie: single hex.
Inlet manifold 10mm (use dwarf spanners or mini internal ratchet ones.)
Exhaust *14mm* usually mixed with 9/16ths

AU Head Gasket
1st stage:30Nm
2nd stage:further 120degrees


And yes, the AU gasket will majorly minimize the chances of blowing again, make SURE you surface the head and clean the deck perfectly.

DO NOT use a wire wheel on a drill, use Gasket stripper and a scrapper on the deck.


AU gaskets also 'up' the compression ratio slightly.
