TD5 Cyl. Head Bolt Torque

(1/2) > >>

turbine:
I would be very grateful if anyone could give me the cylinder heads bolt torque and toqueing sequence for the early TD 5 engine please. I beleive there is a difference in BHP between the first TD5's and the later ones. Do not know if the required torques are different though.
I have a head from another engine which I would like to install on my current motor (cracked head). As a precaution I would like to have the replacement given a very light skim to ensure proper installation. Would this be advisable seeing that these heads are heat treated. Your advice, once again is appreciated.

dont skim the head

That's what Land Rover say... but then I know people who have with out a problem....

Porny:
Same for early and late engines....

Stage 1 - 30 Nm (23 lbf.ft)
Stage 2 - 65 Nm (48 lbf.ft)
Stage 3 - a further 90

Just make sure you use the correct head gasket too.... will be the same thickness as the one your old engine - thickness is dependent on piston protrusion (not head)

Is the 'new' head the same age as your existing engine?? - EU2 and EU3 are not interchangeable AFAIK.

Also make sure you fit the later metal dowels.... rather than plastic.

And use new head bolts (new ones are also prelubricated - so don't use addtional oil)

Not really... but both EU2 and EU3 (post 2002) engines are easily tuned for more power!!!  :wink:
