Hi matise,
So what C3 value have you tried?
Are your two 220 pF capacitors C1 and C2? Or are they in parallel with inductor L?
Following the hints in the Colpitts VFO document linked by Z80, C3 is to be five times the capacitance of VC/C4 combined capacitance.
10 pF for C3 is way too small. This adds nearly 2kΩ reactance in series with the LC tank and that is most likely why it will no longer oscillate. Follow the rules of thumb in the document and your oscillator will work. If the 110 pF (two series connected 220 pF) is in parallel with your inductor, then C3 needs to be 470 or 510 pF.
Really, please post your schematic. Having to guess what parts are where by referencing a third-party schematic, makes finding the solution to *your* problem harder for those trying to be of assistance. One picture can convey 1000 words.
