Need advice on stretch bolt torque (1992 Jetta) - IDI Engine - VWDiesel.net The IDI, TDI, and mTDI source.

• I tightened the head bolts in the proper sequence to the recommended torque using this procedure:
  
  30 ft-lb
  44 ft-lb
  additional 1/2 turn
  
  It says now to warm up the motor, then do an additional 1/4 turn in sequence.  Is this really necessary? Has anyone here not done it? What happened?

• it is very necessary and will probably loose a head gasket in the near future

  I only started it once and haven't driven it. I'll do the 1/4 turn before I drive it. Thank you.

• warm it up to exactly what the bentley says to and go form there. The re-torquing 1000 kms later is the contraversial one

• yea those bolts are so stretched by then....
  a metal head gasket is the reason for part of the controversy i guess
  i havent  checked mine yet
  but im runnin head studs and  its a tdi-m
  i did check em after a few days and i got like no movement,but maybe it wouldnt hurt for me to check mine,,,,,,,,,,,
