Wasn't sure it was gonna budge at first even though I'd been plusgassing it on and off for a day, and just as I was going to get my son to put a bit of muscle on it, it loosened beautifully!

"Remove ALL BATTERY CONNECTIONS,
Remove Heat Shield,
Remove flexible U rubber pipe (Air Inlet to Turbo),
Remove large diameter solid plastic pipe that heads towards the rear of the engine to air filter,
Remove Hatch at the rear of the engine to gain access to the EGR Valve area,
Remove large diameter plastic pipe across back of head, towards Air Filter. Watch the connection with the Rocker Cover Breather and Vacuum pipe,
At this point it is advisable to crack the joint of the Exhaust Manifold to EGR 22mm metal pipe as this can be a pig to undo. Leave for a while pre-soaked with WD40 or similar. We had to use 24inch Stiltsons to remove. It was tight,"

Well done they can be a real B - adun.
Just be careful with big stillies, hope you used it the other way up or you could have lost a digit or 2, probably just took the photo for effect, but for safety etc as peeps may be following your pics.

You're right photo was for effect and I did indeed use it the other way as it "felt" the right way to do it, didn't realise though that there was a proper way so to speak

Your instinct is good.

One way the wrench tightens onto the work piece, t'other way it will open and slip off.

Hmmmmm well Ive just been investigating moving on to the next step of undoing the 3 exhaust nuts which ive now soaked with plus gas.

Looks really awkward to get a socket and wrench on so guess it will have to be the impact gun tomorrow.

[Northern Bongolow]

I maybe would use soft increasing pressure with a good fitting socket as advised earlier.the impact gun will snatch and maybe snap more,
They are usually brass or soft nuts on hard steel studs into ally head, all disimilar metals so they should come apart ok, stud to ally head can lock but heat usually helps.
Just a heads up on the studs, the inlet side studs are of a different hardness material to the exhaust side so when refitting make sure you fit the correct grade of stud.

Ah I may not have been clear I meant the 3 on the joint between the turbo and exhaust, not sure what that joint is called.

Got itchy feet, braved the cold and wind, and went for it and the ratchet gun made short work of it

In true bongo style I've managed it, a lot easier when you remember that you're actually tightening it up and not loosening it as it faces the other way lol.

So it's righty-tighty, lefty-loosey, back-to-fronty...
