[Shotimes] OT-94 Sable 3.8l head gasket replacement

[John Phillis]

Glad you don't work on my cars.

I used to do 4 of these a week minimum when they were recalled by ford... 
Ford lost a lot of money on this one, and as a result the techs were shorted 
on W time.  The fastest I could do a complete head gasket swap was 4.78  and 
I still have the time card to prove it.

No, after you loosen them is when you use go an additional 90 degrees.  If
you retighten them to 75 then you will never go another 180 degrees.  I was
fuzzy on these instructions to begin with and tried that and I'm here to
tell you I was very luck I didn't break the head bolt off in the block.  I
garuntee I was approaching 200ft-lbs when I just could not make myself go
any further because I knew they were fixin to break.

True.

  I don't care what anyone says, ABSOLUTELY.

That is too much torque for those cheesy 11mm bolts.
