Two pieces of good news today...
Firstly, I've solved the issue with the BOV as where it joins to the silicone T-piece it was 35mm, but I couldn't find a silicone T-piece that was 63mm for the intercooler pipe with a 35mm spout for the BOV.
Luckily, while trawling eBay, I found a replacement fitting that reduced to 25mm, which matches the T-piece I already have!
It cost me an extra £11, but I would have thrown more than that away buying a new BOV or buying loads of different bits of pipes and reducers to make it fit!
Secondly.... The turbo manifold arrived from LMS! :thumbs:
