I haven't tried it with PCR, but it worked just fine using an 
oligonucleotide-mediated mutagenesis system (in my case the Transformer system 
form Clontech).  I used a 20-mer oligo with ten nucleotides on either side of 
the three nucleotide gap.  I don't recall what the efficiency was, but I got 
the clone in the first set of mutants that I screened.

Good Luck
