Let the tinkering get serious!!....

Flow through that pipe must be bad. Just look at the profile as it comes out of the DPF.

First thing i noticed too, Gavin.. That's shocking.

[gldgti]

doesnt look pretty, but remember if its just exiting the dpf, its coming from a high pressure low velocity zone, so the effect is not as bad as you might think... what i mean is that having that bend right there is not as bad as having a an identical bend there with a straight pipe rather than a large cross section dpf infront of it.

still, its all a nasty piece of work if you ask me

[Greg Roles]

The actual end shapes of the DPF cannister given the space available is actually excellent, and whilst the pipe is indeed squished and looks bad, they've made it wider so it probably has similar cross section. Still, it is in need of some tinkering no doubt. I'm on it......

On a side note I haven't hobbled my EGR as yet for I can't get the Lamda probe undone! It's a 21-22mm nut, and I've bought two suitable spanners, but the space in there to get some leverage is VERY limited.....hmmm...

Post pics.. One of us might have an idea..

Try 22mm crowfoot spanner.
Sometimes you have to modify (bend, cut) spanner for just one task.

[Greg Roles]

Miro my spanners were bent and cut within minutes, c'mon it's me you're talking to!

[Transporter]

Yeah, I forgot mate, sorry.

I replaced P/S hose on Ford Territory few months ago and despite I bent and grinded right shape from the old (still in good condition) Sidchrome spanner, I couldn't undo the nut at the end of the hose (at very limited space too). The phone call to Snap-on dealer and for $30 I got the 3/4crowfoot 3/8" dr. spanner which was chunky at the right places and nut gave up and came off quite easily.

sometimes it is quicker to just pull the whole pipe out and then work on it. I gave up trying to work on stuff in hard to reach places a while ago now, always seems faster in the long run (between going to fetch/borrow/buy "special" tools, thinking about how to do it and gaffing your knuckles) to just start pulling bits of the car off.

...ofcourse, thats just me.

[Greg Roles]

Stop being so sensible Aydan!

You are right though I'd like to avoid this if possible, as getting the DPF out involves dropping a driveshaft, and I only want to do that once when I put a delete or similar back in. The other hassle is I would have to undo the pressure sensors beside the probe in question, and it'd be a similar struggle to undo.

Here's pics of the space, and whilst the O2 lamda probe unplugs, the plug end is bigger than will fit through a suitable O spanner, and even after cutting a slot in said O spanner, I could't get leverage to even budge it. Ignore the now plugged hole, and the probe I want to remove is to the left. I will check out this magic tool you speak of Miro, and no apology necessary mate, just pointing out I'm quick to get the angle grinder out!




This is the space I have to work with!

[benough]

I'd lend you a ratcheting spanner but it's a bit of a drive...

[h100vw]

FRHM22, Wrench, Metric, Crowfoot, Flare Nut, 22 mm, 6-Point

I forget if they are 22 or 24mm Lambda probes. Might have to go up to 1/2 inch drive.

Not heard that the driveshaft needs to come out, to remove the down pipe. Maybe it comes out with some wriggling?

Gavin

[Transporter]

Yep, 22mm for most of the oxy sensors.



Also I found this bit in the middle (2 of them there - also from Snap-on) very handy in tight places. For removing faulty Oxy sensors I spray it with WURTH Rost Off (great for the exhaust manifold bolts) - works every time.

[Preen59]

Yeah Rost Off or ZEP45 is the go i reckon. I like that offset socket- Never seen one of those before.
