Well since I'm such the dumbass why don't you tell us how to do it
correctly.  I was going by the Haynes manual (not the best I know) so I lay
blame on them if I didn't do it right.  How do you do the correct torque
sequence.  BTW it was my first 3.8 job.   As you've stated you were doing 4
a week.  I can handle working of my cars just fine and I wouldn't care to
work on yours.  I was doing my sister a favor.  It is still running just
fine also.

If you detect some sarcasm you'd be correct. I didn't care for your little
berating little remark thank you very much.   Someone asked a question I
tried to help best I could.
