surely this is fixable

[Teddy Lop]

Exhaust flexi has split where it goes into into DPF (on left).

Mechanic says flexi can't be welded, and is part of DPF assembly and only part you can order is a new DPF kit, which is like a brazillion pounds. DPF itself is fine as far as we know. Surely theres a bodge not bodge that can get this sealed?

Vehicle is a merc vito van with 3.0 V6 diesel FWIW

Yes, at worst you can get replacement flexi sections that can be welded in, provided there's enough pipe either side

Is this the same mechanic who told you the van injectors were knackered.

I'd find a new mechanic.

[steveo3002]

yeah plenty of places will cut that off and weld in a universal flexi

might be better asking places that make custom exhuasts

He has helped me out big time in the past but I think he just get busy and maybe doesn't spend the time researching (he works for a big firm that let him use the ramps for PJ's for friends and family.)

DPF's have been around for many years.

Well tried 2 places now, one looked and said nah, the other thought he could weld in a new flexi but called me back and told me he can't get the flexi.

I really don't understand why this such an issue. It looks like a split that you could just wrap something around or clamp, like a wide jubilee clip or what not. First link below in the right size maybe?. I don't know how well that will clamp onto the flexi - guess it'll need an insert of sorts?

If it's any help, this firm were very helpful when I needed a custom exhaust part for my old 9-5 Aero:

Thanks. Guess I'll be trying to find the axle stands and getting underneath to size it up and take some more pics this weekend then.

I had one go on a road trip in my kit car, sounded normal up to about 3000rpm then got really loud as it opened up

I bodged it together with some drinks cans cut up to make a wrap then held in place with some lengths of welding wire and stainless tie wraps. Had a replacement bought from ebay welded in once I got home.

You might be able to get a universal bellows section to weld into the exhaust, but you will struggle to find anybody to be able to weld that back together.

The bellows section is generally made of two very thin plys of stainless steel, approx 0.4mm thick, and are laser welded in production. Trying to weld it back together, now it is covered in road grime and general crap, will be a real challenge.

Search "exhaust flexi" on eBay.

There are weld on, clamp on, flanged, 2", 2.5", 3", all sorts.

Depending on size, £12 - £16 ish

^^^^ Wot 'e said.

Measure the length of the fitted one, the maximum length you have available, and the O/D of the pipe & get on the bay of e.

You will either find a weld in one if you don't have much space available or a clamp in one that will fit over the cut ends if you have enough space available.

So how is it 3 mechs are telling me it can't be done and I need a new exhaust system running to 4 figures?

Any recommends for someone not too far from Enfield who'd simple fit/weld/whatever such a part onto my van, charge me for his time spent doing so, and allow me to do what I do best and relax when not?

How about a mobile welder like Weldfix?

Because they are not mechanics, they are fitters.

These guys are based in my home town and have used them multiple times for bits. Always helpful and a proper old school engineering shop.
