Dear Gearheads,
I'm sure I've read somewhere that you have to be cautious about torqueing the lower plenum down due to potential cracking- or warping?
In the FSM I noticed that there's a change in torque specs from Nov. '93.
It's a fairly substantial change- up to Nov.'93 11lbs max, after that 17lbs.
Did they upgrade the material in the casting?
I have done some port blend refinements on my '93 lower(pre Nov.), but I do have a '95 lower and am wondering if I should be using it instead-they both appear identical, same casting marks.
My '93 TT is a 4 bolt.
Thanks in advance
