Xantia Td Oil Temp

[elma]

Since I got my car the oil Temp gauge has sat at around 110 rather than 90 degrees as expected. There were a lot of running issues to begin with but now they are mostly repaired. What could possibly cause the increased temperature and how would I check? The car is on about 105k and in a decent state of service although there are a couple of small oil leaks to address from the sump and rocker gaskets at the next oil change.

Possibilities I am already thinking about are turbo seals and inlet manifold gasket. Not sure how to test turbo seals other than swapping the turbo and I have a new gasket to install soon. I don't see why a faulty gasket would increase the temperature, but I suspect it needs replacing anyway so is on my mind.

Hi Elma,

The TD has an oil/water sandwich oil cooler behind the oil filter..

I'd suspect, knowing that you once had some grot in the cooling system, it may be choked o the water side...

I have a couple of spares here so if you want one to try, just squeak..

Another cause I've seen (on an Activa - which has an identical setup) is an airlock in the oil cooler water circuit...

Yes please Jim, is it worth taking the water pipes off it and flushing with a hose today to check first though?

[CitroJim]

Yes, it is Elma,

If not, PM me your address and I'll get one off to you on Wednesday...

Thanks Jim, I'll let you know this evening. I was trying to find an excuse not to change the gasket today, may as well get stuck in.

No joy with the flushing, pm on the way Jim.

Perfect I'm starting to go through my redundant spares now and they're on the list...

I'll get it on its way on Wednesday if that's OK?
