jaymdee Posted June 15, 2007 Share Posted June 15, 2007 OK, Today I drove the car and have a rather loud wooshing noise when Turbo 2 comes on line. The boost gauge visibly drops by up to 0.2Bar if I keep my foot flat to the floor. I've checked the top IC hoses on my FMIC and refitted/tightened (all seem OK), Not looked at the lower ones yet as I did not have time to jack car up and remove undertray etc. I've just tested my BOV (actually have 2) and I can easily blow through it with a foot pump at 0.2Bar (the other, now on the car, is the same) Are both these BOVs knackered, or do I have a major leak somewhere? cheers Link to comment Share on other sites More sharing options...
jaymdee Posted June 18, 2007 Author Share Posted June 18, 2007 Anyone? I've done the TTC mod by changing the VSV hoses and I got a big spike, then when the boost settled it slowly dropped off, again with a wooshing sound. I left it for 4 hours and when I removed one of the vacuum hoses there was a large psssst, indicating the pressure tank and sequential system hoses should be leak free. Are there any other air hoses coming off the manifold I should check? I've tested the feed to the boost gauge (held nicely) and tried the other stock BOV, which I've fitted using jubilee clips rather than the stock Toyoya clips, which seemed a bit loose. Some suggestions please... J Link to comment Share on other sites More sharing options...
