Decided to whip of the IC and give it a good clean inside and out, really easy job tbh. Taking the IC off was a breeze.
I swished some acetone and a little bit of light degreaser around the intercooler for a bit and poured out a dark brown liquid
. Bit of a scrub and it looks pretty tidy now. Haven't really felt any difference but I didn't expect any. Just nice to know there isn't any oil in there now.

Thinking of changing to a GRS before the summer so judging on the ease of removal and refitting seems like an easy DIY job!
