For a TD5 with 180k not chipped (that I know of) gets driven sedately should I worry about this? There's nothing to suggest it happening at the moment.
I'm heading off on a Melbourne to Broome trip in June /July with a large camper trailer, SWMBO and the three kids. No heavy sand, just up the Oodnadatta track and maybe back via the Tanami. Is restudding sensible preventative maintenance?
I have madman EGT fitted. What's a good temp to try and stay below to possibly avoid the warping? I'm also conscious of letting it cool down for 10-30 seconds when parking depending on the driving.
Apparently the warped exhaust manifold is a common affliction not just restricted to Land Rovers.
I would remove the turbo heat shield (3 bolts) and look around the manifold for soot marks and to see if all the nuts are still on and tight.
If you don't have a whistling or chirping noise coming from under the bonnet it's likely that you have not reached this milestone yet.
Mine started to make a noise around 120K and it's been getting progressively noisier since and I've now removed the manifold and will have it machined. Biggest issue is getting the 2 broken studs out! There may also be more broken studs as I want to replace all of them.
