I need to replace the downpipe on my jx engine.

I had a go at this today, over a pit at a mates workplace. The trouble is there is a lot of corrosion and not much left of the nuts and its near impossible to get a grip in them, especial those at the top.

The studs in the turbo dont look too bad, so we are thinking of trying to remove them by locking two nuts together, but were reluctant to try it today for fear of shearing them, I cant leave the van at his worpklace, so any fix would have to be done in a half a day.

Can anyone suggest the best approach for this.
Are special studs needed, brickwerks has these: these for the manifold are they the same as for the turbo?
Also, are the studs left or right hand thread?

Thanks in advance.

Have ou tried heating the nuts up??

heat... cherry red

Tried heating them, but not cherry red, I will have another go with a bit more heat .
They are too worn to get a socket on and access aint too good for a molegrips, what is the best tool for this.

perseverance and using your superior brain over an annoying nut

I've split a red hot one with a chisel before now then replaced the stud

Cheers, I will give it another go, does using the copper nuts stop them disintegrating.

I will be using stainless when my lot come out next

These will grip even rounded nuts/bolts

But! if you havent used heat or something to loosen them, they will give you enough grip to shear the head off, so you gotta be carefull
