Recently I installed an Invidia downpipe, and now I keep having issues with it. I've lost 4 nuts from the turbo to the downpipe, and no matter how much I tighten them, they keep loosening or falling off. Do I need those nuts with the silicone **** in them to stop them from coming off? Loctite? weld the ****ers on? WTF?
odd, normally if they're on there nice and snug they stay in place. you could always retighten them after a drive/afternoon too and while its still rather warm in there, it'd let you get more torque on them and a bit more grab probably. otherwise you COULD use loctite.
i'm currently missing 3 of the 5. >.< looks like I get to hope that the sears auto center will let me use a jack. I'm not paying them to install the 1 ****ing nut I can't get to, and that's the only place within walking distance from where I work. edit. They don't even open till 9, and I only work till 8... I want to go to bed
So only the top 2 are on? I've seen the stud start to back out causing the nut to also back out. It's ok to drive with a leak there so no huge rush to get it fixed. Other than it being really annoying. If you have time this afternoon/evening swing by and we can get it sorted out.
Those will probably not work either. The heat will burn up that silicone in a heart beat. Tried that on my old car, melted it and it STANK!!
I agree. Use OEM bolts. They should have a knurled mating surface to prevent them from backing out. The heat produced is going to make silicone/loctite/etc ineffective. I would double check for loose studs, because that could also cause them to back out. On my car I've found that I can use a standard length socket and 3/4" drive ratchet, and reach 4 of the DP bolts from the engine bay. I have enough room to put a breaker bar onto the ratchet, so I have no trouble at all tightening them to stud-snapping torque (if I so desired). The bottom/middle bolt is tougher to reach (especially with my EWG installed), but I can also reach this one from the top. I just reach my hands around the turbo and use a closed end wrench. No breaker bar, but I can get it plenty tight. Just a thought. I'm sure there are other very good methods for tightening these bolts down. I previously had done some of the bolts from the bottom, but I find that working from the top allows more room, and I can get them very tight. Another couple notes: As already mentioned, a post turbo exhaust leak isn't going to hurt anything. It's just annoying. Also already mentioned, retorquing after a few heat cycles, and while the car is still warm (but not burning hot), will often allow you to snug them up a little more.
Got oem stuff. And a side of deez nuts just in case. I'll chuck them on in a few minutes, then warm the car up and retorque. We shall see how that goes. Hope no more issues. Wish it was vband instead lol
I was thinking the exact same thing last night when I was removing/reinstalling my exhaust manifold/uppipe/EWG/downpipe.
Brett, this has happened to me as well. I haven't lost 4 of the 5, but the last 2 time that I've had to remove the down pipe there has been 1 missing. I've probably removed and reinstalled too many times.
Well, oem replacements are on. Tightened as much as I physically can. Hopefully that solves it. If not, time for locking hardware.
