The weather hasn’t been very good since I got here, so apart from walking the dog and getting my bearings I’ve not really walked anywhere. It’s about 40 minutes into the old town from here and because the rain is on and off I decided to leave it for now. I’ve got tons of photography work to be going on with especially due to managing the change of not using Lightroom and moving over to other software. *groan*
Anyway, I looked under the van to find out what’s going on with the exhaust and spotted that there was a clean break in the front part of it. It’s where the front pipe connects to the catalytic converter and the weld has just completely sheared, almost as if it’s been cut.
I wondered if it had as years ago I heard of people cutting cats off cars because they were worth so much money, but it feels as though the break is quite rough and although I can see clean metal most of it is dirty so nothing suggests that it has been cut with anything and thinking back it’s been a while since the van was last left long enough for anyone to do it. Also by the look of it there’s not tons of gas marks, so I suspect it hasn’t been broken long. One thought was I wondered if this could be the culprit for my excessive fuel consumption but again due to lack of gas marks which suggest a long term leak I doubt this has been a real problem. I suppose it’s worth finding out though if a faulty cat can cause other problems?
Anyway I was thinking of what I might be able to repair it with. The break is clean so I can’t use gungum, which may be too flimsy anyway as it’s more of a sealant than an adhesive. Exhaust bandages aren’t much good in my experience and I don’t have one anyway, but I found something I’d bought ages ago to try out called Fiberfix. It’s some kind of tape that you activate in water and then wrap around whatever and it apparently seals hard enough to be able to be used to fix garden fork handles! It actually states it can also be used for exhausts so I tried it out.
They were right too, after 5 seconds in water I started wrapping it around the joint and I could feel it curing n my hand. I was forced to use pliers to get the plastic core loose as when I got to the end it was sticking so strongly that I could not tear it free with my fingers. Bloody amazing stuff.
I checked it next morning and it appears to be as hard as steel. Whether it’ll be enough to seal the gases in and hold the two parts together when driving is another question. As you can see it’s not the neatest job in the world, the very end is curled over somewhat and that’s where it was curing as I worked so I could not flatten down the last half inch. As I said it was curing in my hand as I worked so from opening the packet to it curing in my hand I’d say it cured in about 3-4 minutes. To the touch it is very hard and at least it looks as though I’ve managed to get enough overlap of each segment of pipe.
I ran the engine for well over an hour and for the first time in ages my exhaust smelled *bleachy*. That’s a dead giveaway that the cat is working now, so I know it hasn’t been for some time as the exhaust has smelled awful for weeks. It’s still running and although there was quite a bit of smoke in the first 20 minutes, that seems to have disappeared now, so I;m hoping that was burn-off from the cat. This Fiberfix is a minor miracle! Although I still need a garage to sort it out properly.
Cat’s aren’t stupid money anymore now though, I’ve seen them anywhere from £60 to £160 and this one is the original from 2004 when I bought the van so if that’s what’s needed then so be it. Now it just remains to find an English speaking garage near Santiago…
