Sport melting manifold

Its not really a sport but disco 3 with a TD V 6 2.7 diesel. This car has been run around town and a carbon build up in the inlet manifold and where the EGR enters the plastic manifold. I was driving at about 60mph but the outside temp was about 36 c and the MIL light came on and black smoke out of the exhaust . stopped the car and opened the bonnet and there was smoke coming from around the manifold somewhere.
Stipped the manifold off the car and found that carbon build up had ignited and blown holes in the plastic.
One cure is blanking plates for the EGR but you also need a software patch. When I get it running again I will use some manifold cleaning agent to try and clean all the carbon build up out of the plenium chamber .
apparently this is quite a common fault so it might be worth cleaning the manifold about every 50000 miles
subaru recommend this on their cars as a standard service item. if the manifold is off the car oven cleaner works well.

I have just fitted the new(second hand) throttle body and would put a picture of the old one with the burn holes in it but cant work out how to do it , it used to be easy with the old format. Before I fitted it I used a tin of oven cleaner to get rid of any carbon in it and there was quite a bit. I have also run half a tin of liqid moly diesel engine manifold cleaner through it and will use the other half today.
The parts supplier that sourced the throttle body from sent a flyer with it about a plastic coolant valve (water outlet ) that is prone to failure and can supply an aircraft grade aluminium one that is guaranteed for life, not cheap at $595 AUD . and on checking mine found that it already had one fitted so ok there.I would also like to scan the flyer and post it on here but it to haed for me being an oldie and cant be arsed to try and work it out as life is to short and still plenty of other places to go like the greenland coastal trip later this year. and also prepare this Disco for the desert tracks out here, It will be nice to do them in something comfortable air conditioned and quiet. the last time i did them was in a SWB series 111

as i said before i cant work out how to post photos on this site any more otherwise i would have shown a photo of the burnt out throttle body.
I used the manifold cleaning spray and i think the amount of smoke that came out of the exhaust would make a hole in the ozone layer for the next year so i hope it cleared some of the carbon from the manifold , I will use the rest of the tin sometime to try and get any thats left.
