Won't be going hybrid as i would need an uprated intercooler then
had a look and there wasn't any oil splattered over the turbo and when revving when stationary there's NO smoke at all

the noise appears without fail at 2500rpm and goes by 3000rpm
Had a look at all the pipes but couldn't see anything obvious - will check again in the morning for leaks. I'm hoping its something simple such as a perished o-ring around the intercooler pipework
