Too rich 5kcstq - idles now, oil everywhere

[Barry Babcock]

I have to take back what I said about my car.  It's not a heap.  It 
finally showed me some love- I got it idling and tuned the CO screw as 
suggested below.  Whew.  Just took a bit more patience.

Thanks for  the hints guys.  I'm back in business.

Now if I can get a handle on these oil leaks.  My valve cover is leaking 
like a sieve.  I torqued the nuts to 7 ft-lbs per the Bentley, I'm using 
a rubber gasket with those metal rings in it- I didn't screw up and 
leave the gasket folded over...

Should I use some gasket sealer on this?  Throw it away and use RTV? 
 Just tighten the nuts some more and ignore the Bentley (again)?
