Hi there, today I tried to remove the heat shield on the turbo so I can start to plan where I can put the pyrometer probe on the dump pipe. I got all bolts out except the one at the backside with the head of the bold facing the fire wall. Is there any tricks you guys use to remove stubborn bolts? I have tried using a ring spanner but it starts to deform
The bolt head this also happened when using a 6 point socket and breaker bar. I did think maybe I could weld a bar onto it to try and turn it, but only wanted to do this if necessary.

Get sme WD40, spray liberally, let stand and they'll come off easy. This is how I did mine: http://www.patrol4x4.com/forum/showthread.php?t=55831.

Don't use wd40 (Its just fish oil) . Go and buy some Super nut breaker (White can with red writing & found in the Bunnings toolshop.) or some crc freeze spray from Repco. Get a spanner with flat sides instead of one that has a point that touches the sides. Do not use cheap spanners on jobs like this or you will just round nuts.

Yep, that's the one on the "cat", use stuff like INOX or brake fluid but be careful around bodywork and plastics, let it soak for a while and it should work. Good spanners/sockets to use are the so called "Metrinch" type those grab on the flat side of the nut/bolt head so they're capable to undo even rounded of fasteners. Or go for the so called spline drive spanners/sockets but they are rather expensive. If you can swing a hammer there try to give it (the bolt) couple of hits that shock usually loosens up stubborn fasteners too. Use a punch, e.g. brass type so as to avoid damage to the bolt hex sides. When everything else fails use the blow torch to heat it up. Take care with that.

i'd have to agree with rumcajs, metrinch spanners are an absolute pain in the arse under the engine bay because of the amount of play they have, but when it comes to rounded nuts & bolts you can't beat them.
I just removed mine & was lucky enough to get all the bolts out hassle free. The hardest part was actually trying to feed the shield out without removing too much other stuff under the bonnet.
Good luck.
