I think Berg says not to use Teflon tape, and if you read more of his stuff, 
you will find that what he means is that the Teflon tape is likely to make the 
joint so "slippery" that you will be tempted to overtighten the tapered pipe 
threads in the case and crack the case.

You really need to use SOMETHING in there to seal the fittings. There's 
nothing wrong with Teflon tape if you use it carefully and keep in mind what 
the hazards are. Other options are some of the Loctite thread sealing 
products, which are very good.

Proper use of Teflon tape means, among other things, not letting the tape 
hang over the end of the pipe fitting where it will be sheared off and released 
into the oil stream. It should be kept back one turn from the end of the fitting.
