Downpipe technique!

[twoqu]

Hello!

Can anybody enlighten me on how to get the bottom nearest the manifold nut that holds the downpipe to turbo undone. Access is really limited and I can only see it being moved by something like an obstruction wrench/spanner.
Unfortunately I lacked the insight to source one before the weekend and only have conventional weapons at my disposal!

I used a short spanner which took ages but ideally you want a half moon one because like you say access is crap down there!

I think this is the one that need a "bent" spanner.

Have you done a search? I suspect there is a guide somewhere...

Cheers,

Something along these lines:

Halfords also do a nice set, its £49.99 iirc.

Good luck

Thats one kinky spanner!

Thats the one used by Jon for Ross's GT3071 build right?

That looks like Uri Geller had a go on that when he ran out of spoons. Still, I'll bet it does the job nicely.

Thanks guys!
I'll see how frustrated I get tomorrow. Hasn't been on there long so its just a matter of getting it started. Might improvise with a cold chiesel and lump hammer and sort out the correct tool for its replacement.

It's one of those jobs where a spanner ends up being cut down...

Oh this is a fun job..

Make sure that nut is the first one you take off..tighten the rest up first before attempting to loosen it (less pressure against it )..I ended up making up a socket that can fit over it ..but had to grind socket so it was thin/short enough to slide through gap ..hammered socket on first .got a wobbly joint attached then came off no problem

I usually use a spanner set like this

[GT500]

I use a short 15mm 3/8 drive socket, ground down on its rear end, sort of cone shaped.
Wobble drive extention, works great.
Unless some turd has lost the factory nuts and fitted the 17mm usual M10 nuts!

Ok, I just thought I would post my solution.
I had an awful feeling that it wasn't necessarily going to be as straightforward as buying an obstruction spanner of the correct size. I was right!
I searched Ebay for the cheapest obstruction spanner in the correct size, 15mm. I found a set of three for about £3. They arrived today. As I suspected the spanner would only locate on the nut in one position, jamming the straight part of the spanner against the exhaust manifold. So I attacked it with the grinder until I was able to get it on in a position where I could get some leverage. It ended up looking like below. If you look at the amount of material on the other end (right) it should give you an idea of how much material had to be removed.
That works a treat. So there are more than one way to achieve the objective.

I get to mine from underneath the brake fluid reservior with a ratchet and a few extensions, using these
