if my turbo goes will oil come out th i/c and will the car overheat cos thats what is happenin in my VRS

Not quite sure - some turbo can come out of the intercooler.

btw in case you have the 1.8T in your Octavia vRS, the turbo that's coming off my PD130 won't fit your engine unfortunately :(

Oil in the intercooler is quite normal i beleive as most cars have traces in the system but if its putting oil into your exhaust system and smoking then i would think your turbo seals are shot,i've experienced this twice now
