So, had some issues doing ym N249 bypass tonight. Not really with the bypass itself, but noticed that my FPR vac line was completely disconnected from the inlet manifold, no idea how long it's been like that. See here: Disconnected hose found while doing N249 - help please!! I want to drive home!!
So, managed to change the FPR line as I was doing that kind of thing anyway - changed it and the SAI lines to silicone hose. During the N249 bypass, changed all hoses apart from the existing inlet manifold vac line to silicone. Started the car and it was fine, no warning lights or anything. However, I think I can hear a leak from the area highlighted below:
Maybe paranoia - but think I could hear it slightly when driving home. Car still feels ok, but could swear I can hear a leak from there. Can't feel anything though. So, as the red circle shows - I think it's coming from the area on the inlet manifold which has the 2 nipples - one connected to the existing vac line (which I did not replace for new silicone) and the other to the FPR line I just changed. All hoses I changed are secured with small cable ties and are a tight fit anyway. So I'm thinking it can't be the FPR line making that noise - especially as I think that line has been completely off for a while anyway and I didn't notice it before.
The only thing I can't properly get access to and see is the nipple which connects to the existing inlet manifold vac line. Does anyone have a picture of where that connects? Feeling underneath the manifold, i'm finding it hard to tell if it is still tight or split etc.
On the same sort of topic, I might want to get a boost leak check done - anyone know anywhere in Surrey which does it well at an affordable rate?
Thanks guys! Appreciate the help
