  We give a progress report on a snapshot 86 GHz-VLBI survey of the EGRET
blazars with the observatories of the CMVA. A high fraction (17/18) of the
EGRET blazars were detected on the Pico Veleta-Onsala baseline with a baseline
length on the order of 500 $M\lambda$. The detection threshold on the Pico
Veleta-Onsala baseline was $\sim 0.2$ Jy. Six of these sources were not
previously detected with 3-millimeter VLBI. We also present the detection of
three new non-EGRET sources. The high detection rate for EGRET sources
indicates that gamma-ray flux is a robust predictor of millimeter wavelength
intensity. Future more sensitive high-energy gamma-ray experiments should find
a larger class of objects detectable with millimeter wavelength VLBI.
