Hi Darrel.

If u look through the driver/ of side front wheel arch using a torch you may be able to see the problem providing its the Cross over pipe, but to make sure if you remove the engine shield from underneith you will be able to reach up and check the COP using your hand, while the engine is running. Generally it is the flexable sections that fracture or burn out.

You are looking at a good days work, doing this how described providing you have decent tool that have fine ratchets since some of the COP bolts and heat shields have little space to allow you to shift the tool, so these have to be shifted in small incraments at a time. It's definiately not the easiest job doing this in situ but will save you a small fortune!.. The pipe is around £500 and can be purchased with a forum members discount Through D3 by contacting the Big one.

Best of luck.

Regards Kyle

As for cost, I was quoted £2200 in the midlands to do the job……..

If it does inculde a brand new pipe, maybe it isn’t
but otherwise if you devide 2200 quid by 12 hour work, incl a body off-body on it will be 180 quid an hour
At least that is not what we pay an hour at this side of the pond…were 55 till 75 € is more common (incl VAT that is)

Hi all
Maybe a silly question, but let’s go for it

I’m attempting the replacement of my COP 12 months after the last aborted attempt…..

To undo the near side COP nuts, do you go in from engine bay, wheel arch or underneath (or a mixture. Lol)

Cheers

Hi All,
Well after reading this write up https://www.disco3.co.uk/forum/topic116505.html (many thanks Trex-On) I thought i would have ago in removing my crossover pipe so I can replace it.
The write up is spot on however having removed my crossover pipe I've got a little info that might help?
1, The Exhaust nut's are 1/2" not 13mm this is why so many people round the nuts off even using 6 sided sockets.
2, Remove the front prop shaft. This will make life so much easier.
3, You do not need to remover any EGR cooler units. I only removed the EGR pipes as I also blanked these off these at the same time.
4, Before removing the crossover pipe you will also need to remove the fuel filter.

Tools I used
1, 3/8 sockets set. this included 1/2" socket 6 sided. (I would say a multi point socket will work but safer using 6 sided.
2, 1/2" spanners that you can cut down. This was used for the 2 impossible nut's, the first being drivers side, nut nearest the engine. The second is the passenger side top nut. What i found was a long push bar 50cm x 5mm x 15mm help by pushing on the spanner to crack the nuts loose.

The crossover pipe will come out nice and easy from the drivers side, I was surprised how much room you have.

I've got to fit the replacement unit this week but my hands need a little rest
If anybody needs more info i might be able to help. I'll update once new unit fitted.

Just for Reference refitted new 8mm nuts that use a 13mm spanner.

Good luck and many thanks
