surda Posted June 23, 2016 Posted June 23, 2016 Hi guys,so today, I wanted to take off the exhaust. As I failed, because it wouldn't come off, I wanted to put the screws back in place. As I tightenone of the screws, a little crack appeared (see attached photo). Should I be worried about it? What can I do to repair it?I would like to exchange the downpipe for a new one, but I am scared now, that whatever I do to it, its gonna make it even worse.Thanks for all responses Quote
Tiggie Posted June 23, 2016 Posted June 23, 2016 I wouldn't worry too much but its probably best to leave the downpipe on now before it gets messed up any further I would buy some hi temp metal expoxy and try and fill the crack with that. Or take it to a garage for a weld if you are really concerned Quote
Guest Posted June 23, 2016 Posted June 23, 2016 Done many a repair to engine cases and sections and all have been successful with JB weld. This is the best you'll get as it maintains a heat threshold well above what others can offer and also is one of the strongest as well at nearly 4000psi when fully cured.Mix it up, put it on when cold and leave it for 24hrs. Sand down after that if you wish. Quote
Tiggie Posted June 23, 2016 Posted June 23, 2016 Phil:JB Weld is what I would of recommended but I couldn't remember its name and couldnt be arsed googling Quote

Rik398 Posted July 15, 2016 Posted July 15, 2016 Jb weld, or you can also buy aluminium brazing rods, looked into them a while back but never went for them. Quote
