Anchor Member 270 Member For: 15y 2m 27d Gender: Male Location: Rockhampton Posted 13/04/10 10:14 PM Share Posted 13/04/10 10:14 PM Right, normally I'd just check for boost leaks etc.. But this one is weird.Was sliding around the other night, hit limmiter a few times etc etc. Then driving normally on the highway at 90km/hr I noticed the boost guage wasn't moving. Foot on clutch, didn't even go into vac. Foot down, wouldn't boost, just fluttered back through turbo and acted like a NA 6..So I pulled up, put the clutch in, sat there for a minute and then took off again. Everything seemed to be back to normal except for it now only boosts to around 6psi instead of spiking to 12 and tapering back to 9. Boost guage was really shaky as well. Yesterday at work we replaced the wastegate solenoid and checked the cat to see if it was blocked. This didn't help. Can't find any boost leaks etc. Kinda lost at this one..Any tips or sh*t I can try will be appreciated :DJeri Link to comment https://www.fordxr6turbo.com/forum/topic/67545-weird-boost-leak/ Share on other sites More sharing options...

Nothing extreme as its the daily driver. Was on dyno only last week.

It may have popped the vacuum line off that goes up to the BOV Link to comment https://www.fordxr6turbo.com/forum/topic/67545-weird-boost-leak/#findComment-1000304 Share on other sites More sharing options...

Anchor Member 270 Member For: 15y 2m 27d Gender: Male Location: Rockhampton Posted 14/04/10 08:26 AM Author Share Posted 14/04/10 08:26 AM Reloaded tune and checked all vac and boost lines and ic piping. All good. BOV was a little loose.. It's a turbosmart 38mm item on the turbosmart intake pipe. Instead of just tightening the grub screws I pulled it off and the o-ring doesn't come out past the inside metal of the bov. That could be it right? Gunna throw on another 38mm bov I have here with a good o-ring and see how it goes.

Took it for a drive, still gay. Only makes 4-5psi and the guage is shakey as hell. Feels slow too.

If you are sure that everything else is tight, that's the only things it can really be.

It idles fine and drives fine. No weird noises etc.. Just doesn't go as fast or make anything over 5psi.

T piece had split from heat. I couldn't see it. Local tuner fixed it for me on his lunch break <3 Link to comment https://www.fordxr6turbo.com/forum/topic/67545-weird-boost-leak/#findComment-1000737 Share on other sites More sharing options...
