They are not all that difficult to change.
I usually lower the rear of the engine some though, that really helps with
access, but it's not absolutely necessary.
All you have to undo is the 3 bolts to the cat, and the support bracket on
the right side of the engine.
what I commonly find is the nuts and bolts are really rusted, and half the
time I heat the nuts with a torch to be able to get them off.
If the engine isn't lowered, then you might need a 'heater box wrench' which
is a 13 mm hex box wrench, built in a curve, so it can reach around corners.
And rare is the intact and complete support bracket ( support bracket system
I could say ). Most I see are broken, missing pieces, or have been hack
welded to get them to work a little bit more. It's about 5 parts all
together. I have most of those parts.
parts wise , you need the muffler, gaskets at both ends, and tail pipe.
I often undo the cat and muffler with tail pipe as one piece..........so I
can see the upstream end of the cat material inside it.
With that part off the car, the bolts between cat and muffler are easier to
deal with.
I don't know how I'd work on this stuff without a torch really, most of it
is so rusted and stuck.
here's trick to remember if flame heat is available........get the bolt or
nut pretty hot, and melt candle wax into the threads. It'll get sucked
right into the threads, and sometimes that makes them be able to unscrew
like they should.
here's a great upgrade to a 1.9 waterboxer. Put on a rear engine mount
aluminum casting part, from a 2.1 waterboxer engine.
That system uses a great 'cradle' arrangement to hold the muffler. You just
use the right side of the double cradle system to support your 1.9 wbxr
muffler. There's some welding and minor modification I think, but this
would make a 10 times better muffler support than is stock on 83 to 85
Vanagons.
I don't think I have any extra of those brackets right now though .....
but it's a vastly superior way to support the muffler, compared to what the
1.9 has. If I find I have an extra one, I might build up 'the perfect' 1.9
muffler support thing using 2.1 parts, and offer it for sale.
or you could put on an entire 2.1 exhaust system too, but that would be
expensive and make a lot bigger project out of it.
The ones I get are decent European made, good quality aftermarket mufflers.
if you want a price quote, let me know.
And see if your right side muffler support bracket system looks ok. Many are
broken or hack welded .
