Ok so I've removed everything for access to the DPF. Only things left to remove are the actual DPF nuts, but they've rusty and one's now rounded! :(

Any ideas how to remove it, hopefully before it gets dark!?

Cheers

Have you got a good blowtorch? Get some heat onto it, preferably glowing red.

As for the rounded one, spiral sockets are good for dealing with them but again I would want to heat it up until it glows red to try and break the corrosion bond

Are you using hex sockets and not bi hex?

No blowtorch unfortunately. Only have a heatgun. :/

Yeah using 6pt, wouldn't use anything else on rusty stuff. Unfortunately I thought the impact gun might break the corrosion...all that did was round the nut. Fail...

WD40 and maul grips.

+1 plenty of WD-40 let it soak in,

Be surprised how effective it can be.

Or PlusGas.

Plusgas is definitely a superior product

I've just learned something new today :)

It makes lovely white smoke too Lenny when you spray it on a hot surface

WD40 is basically water compared to plusgas...had already soaked them in it lol.

Anyway, somehow during eating pizza and panicking about this the nuts loosened and I removed them easy after then! They're copper as well...so definitely not rusty.

Got all sorts of other issues now though, wishing I hadn't attempted it now. I like working on cars, but not when its a daily and not in the mud pit that is my drive in the rain. :/

So its even approved by the Vatican ?

If you get stuck again, a nut splitter is quite a handy tool.

Other methods:- try tightening before loosening, hammer and chisel to shock them off, hammer a slightly smaller socket on to rounded off nuts, there's some other things to but hard to describe.

Are they not just copper flashed? Same as with manifold nuts

Glad you got that problem sorted though

I'm not sure, they're really soft though, tapped a smaller socket over the rounded one with barely any force at all!
