keithk831 Posted September 15, 2010 Share Posted September 15, 2010 We installed a catted downpipe on my friend's 05 5EAT, and he forgot to tighten the cap that plugs the spot for a wideband. A week later it popped off, and after a little driving (he drove it home, then to my place to get it checked) this is what the LV looked like... Note the IAM value. Needless to say, I had him park it until the replacement cap arrives . Should be any day now. Link to comment Share on other sites More sharing options...
rao Posted September 15, 2010 Share Posted September 15, 2010 You can use an old spark plug or a M18x1.5 oil drain plug. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
Legend Posted September 15, 2010 Share Posted September 15, 2010 Wow so the CEL must have caused the IAM to go to zero, eh? I keep my plug on very loosely... just finger-tight and then a half turn with the wrench. That, and a bunch of anti-seize. I take it off at least once a month for logging AFR's. My last 02 sensor seized so I'm more liberal with the anti-seize and not so liberal with torque. I imagine it was a little loud and/or smelly in the cabin with that plug off.

Boostin1657615274 Posted September 15, 2010 Share Posted September 15, 2010 If you don't plan on removing it again, put some threadlocker on there. On the search for a new DD... Link to comment Share on other sites More sharing options...
keithk831 Posted September 15, 2010 Author Share Posted September 15, 2010 I tried to find an m18 oil plug but the largest they carry is m16. And yeah, we are going to use thread locker on all the dp bolts and that one. Link to comment Share on other sites More sharing options...
mattg Posted September 15, 2010 Share Posted September 15, 2010 Surprised a little post turbo leak would cause all that. Would a leak between the DP and mid pipe do that as well, or only pre-o2 sensor? Link to comment Share on other sites More sharing options...
keithk831 Posted September 15, 2010 Author Share Posted September 15, 2010 It's really because its before the o2 sensor. And it sounds like he has hogzaust haha Link to comment Share on other sites More sharing options...
