I take it it's the xu engine, the haynes joke book says

 

main bearing cap nuts and bolts 49nm

main bearing cap side bolts 24nm

 

big-end cap nuts

stage 1, 40nm

fully slacken all nuts, then tighten to

stage 2, 20nm

stage 3, tighten through a further 70 deg

 

as i said thats the haynes hope it helps

I just cannot believe it.

Yes I know what Haynes says, and I've raid http://forum.205gtidrivers.com/index.php?s...hl=mains+torque too.

But it's just not very tight is it???

 

Have people successfully put their engines together with just using 50 Nm on the mains????

I want proof before I believe it

i have got a glass's tech service data book from 1988 and the torque settings listed in there are as follows:

 

cylinder head bolts - 60nm - 44 lb ft (loosen, then 20nm/15lb ft +300degrees

big end bearing bolts - 50nm - 37lb ft

main bearing bolts - 50nm - 37lb ft

flywheel bolts - 50nm - 37lb ft

clutch to flywheel bolts - 25nm - 18lb ft

I used those figures on the engine currently in my car & so far I've had no problems revving up to 7k.

(I actually used the Autodata sheet torques as they are more progressive on the headbolts)

Autodata tightening torques for a 1990 GTi;

• Big end bearings;
  
  
• Tighten in the following stages:
  
  
  1) 40Nm
  
  
  2) Slacken off
  
  
  3) 20Nm + 70'
  
  
   
  
  
• Main bearings;
  
  
  Horizontal bolts = 25Nm
  
  
  Verticla bolts = 54Nm.
