Exhaust mounts.

[Boblong]

Firstly, I'd like to just quickly say hello and introduce myself and my van. I used to be a member on here years ago but lost my username after years of inactivity. My syncro was put into storage (really badly) and only recently got back on the road. There's a lot of work needing doing on it (Simon from Brickwerks said he'd never needed 3 pages doing a write-up before!) but its a good old van and worth the effort it's gonna take to sort it out. It's a factory hi-top that has old triple-holes where you'd expect to have beacons on the roof and there's a disconnected siren behind the headlight grillle. (Any ideas? I'm guessing airport ambulance or something)

Anyway, I'm sure you'll be seeing plenty of questions from me in the future.

At the moment I'm trying to sort my exhaust. I've had to change the rubber mounts before and at one point the triangular "rip-plate" (the triangular-ish one that attatches to the back of the sump) actually snapped in two. I had it welded and replaced the rubbers. Eventually the rubbers split again and this time the exhaust pipe snapped at the manifold end and was dragging behind me. I replaced the whole exhaust and mounts but found I had to push the muffler box down and forwards to get the rubbers to locate in the mounting plates. In other words the exhaust "wants" to be slightly higher than it is when bolted on, and there is a constant strain on the rubbers. I've just bought a new rip plate from Futbus and am going to have about 30mm welded onto the end of it so the new holes locate on the bolts without being under pressure.

My question is, is doing this advisable or is there something else I can do to reposition the exhuast so it sits right on the mounts?

Thanks, Bob

Maybe put up some pics of underneath and all of the exhaust section ? Doesn't sound right could be wrong j pipe ?

I assume its a diesel we are talking about here? Something is not right so the first question is where did you get the exhaust from?

[Boblong]

Yep. 1.6TD. Although Si at Brickwerks reckons its not the original engine, he didn't mention the exhaust so I reckon its ok. The exhaust was from the old gent at GT autospares, (think he's retired now) The one he got for me wasn't the same as the one that was on there when I bought the van, but he told me it was the right one and it fit the mounts without too much of a struggle, so I was happy.

It is only slightly out of position and the rubbers held for 2 years last time I changed them.

I'll post some pics when I get a chance.

There are early and late exhausts.
Wasn't your van a late one? G or H reg?
Sounds like you've put a early exhaust on what was a late van.
Infact, I just found the report, you have a late van "H" reg, so you should have the late system.

From your report.
• Exhaust silencer mounting missing [left hand] both rubbers split/perished.
• Exhaust silencer mounting rubber also split to the right hand side.

Please also note other faults in the same area.
• Turbo oil feed pipe corroded.
• Turbo oil return line corroded and kinked.
• Turbo air inlet pipe [plastic from air box to turbo] split and drawing in unfiltered air, suspect damage to turbo.
• Bolt missing from exhaust manifold on #1 cylinder however not leaking exhaust gas.

The down pipe is different as it has a flange fitting to the silencer, the silencer has different mountings and is physically longer.

Thanks Simon.
The late exhaust in the picture looks identical to what's on there now. Mine has the 3 bolt flange on the end of the downpipe too.
The old exhaust was definately a lot shorter than the current one (about 200-300mm shorter)

If I am running the wrong exhaust, would that impact performance?

Also, what's the average life of a silencer? As I said, this one's been on for about 5 years now.
