The added varactor circuitry will introduce additional phase noise, 
from both leakage current in the varactor and noise on the varactor 
bias (just from the new bias supply, if you use a varactor that was 
already there).  Perhaps not enough to be problematic, but it will be 
clearly measurable unless the original circuit was badly designed.

Best regards,

Charles
