Think I went through four new stats before getting a good one in my own 200tdi. I had this with waxstat too. The vdo guage was showing it wasnt opening until 97C! Soon took that one out!

Mike Going by the quality of pums these days, if it feels like that, check it, new or not Quote Link to comment Share on other sites More sharing options...
miketomcat Posted September 1, 2022 Author Share Posted September 1, 2022 Radiator was fine before the head gasket so doubt it's changed. Changing the thermostat made no difference to the symptoms so that should be fine. It's possible the head gasket has gone again but last time it didn't get hot until it was utterly dead (it took 700 miles of towing to kill it completely).

Quite possible after many hard miles on a blown head gasket.. I'm beginning to think the same. Fridge has given me some leak dye so I'll try that and if nothing the head will come off and I'll check/skim it. If I can get this one to behave I can buy time to sort the other one.

miketomcat Posted September 4, 2022 Author Share Posted September 4, 2022 So I've put the leak dye in and been for a drive. The good news is there's no sign of a leak. The bad news is I've lost some water and there's no sign of a leak. Mike Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted September 4, 2022 Share Posted September 4, 2022 I think along with @Mo Murphy's issues it's a sign 200Tdis aren't long of this world anymore and everyone should be switching to V8s...

It still astonishes me that the most economical engine land rover ever used in a defender/discovery is a 35 year old design with roots going back even further.

That just costs you more money in gearboxes though big diesels and LR drivetrains never seem to get along. Also, conversions bring other issues and I doubt many will better the 200's MPG in a 2-ton brick - certainly not enough to pay for themselves. 1 Quote Link to comment Share on other sites More sharing options...

miketomcat Posted September 5, 2022 Author Share Posted September 5, 2022 The 200/300 TDI takes some beating. Conversion doesn't make sense. Just need to get one or both these engines sorted. Mike Quote Link to comment Share on other sites More sharing options...

I had a similar problem with a 200 - it was drinking a couple of litres of water every 100 miles with no obvious leaks, no water in the oil. Chemical test showed positive, changed the head gasket and the problem went away! 1 Quote Link to comment Share on other sites More sharing options...

Chemical test showed positive, changed the head gasket and the problem went away! To be honest I think I'm beyond tests, I'm fairly sure the head gasket has gone again. I think the head needs skimming but to be fair it got us home so I can't complain. I might drag the head off the other engine get it skimmed then I can just pull this one off and swap. That way it's off the road for the minimum time. Then I can get this one skimmed when I rebuild the other engine. Mike 2 Quote Link to comment Share on other sites More sharing options...
Maverik Posted September 5, 2022 Share Posted September 5, 2022 It seems to take only a couple of thou out and they start to leak, I had a similar carry on earlier this year after I'd had the head off and given it a clean up myself with a bit of scotchbright - I spoke to the chap doing the skimming and he confirmed they're pretty "sensitive".
