Though I'm not directly familiar with your model Pathfinder, I'm pretty good with frozen & broken fasteners. Can you post a clear photo of what you're dealing with?volox wrote:I've got a 95 Pathfinder and I'm trying to get the passenger side exhaust separated from the exhaust manifold. With great effort I got 2 out of 3 bolts loose but the one on the underside nearest the oil filter simply will not break.
I've now tried nut breaker to no avail. It looked like there was a flame on the nut that was keeping it from breaking, so I ground the flange off on the side I had tried to crack; still no dice.
Now that I've mangled the thing and it still isn't coming out, any suggestions on how to get those two parts apart?
unfortunately from your picture, I can't tell which fastener you are working on. is it a nut on a stud, or a bolt? but either way, can you grind the nut or bolt head completely off, remove the exhaust, then extract the remainder of the ground off fastener from the manifold (even if you have to remove the manifold to do so)?volox wrote:Thanks for the suggestion smj999smj, but that doesn't help in this case.
Even through the wheel well there isn't any better way to get on it because the fuel lines run up that side of the engine compartment so the swing into gap of the wheel well is blocked.
At this point it's not so much about how to get at it as it is about what to do with it. See the pictures and you'll understand why.
No magic really, just techniques, which depend on the nature of the problem.volox wrote:Thanks eieio
On the other side, it was 3 bolts that were on studs. On this side I had one bolt come off the stud; the other one the stud unscrewed - I guess the nut got hard locked to the stud.
So this should be a nut on a stud, but it looks like someone used a bolt with a larger flange on it than any of the others, which is probably why it's been so impossible to break loose.
Grinding the rest of it off was kind of what I thought was going to be the next step. Was just hoping there might be some other magic.

It may require manifold removal to extract it.volox wrote:If it was accessible, that's when I'd get the drill out; but in this spot I know I would never be able to get the drill on it.
