Oil in the Water on 306 HDI

Post by PJB » 02 Aug 2003, 17:41

I own a 2000 306 HDI, and have had over 18 months trouble free motoring.
However I now have oil in the water, however there is no water in the oil, so doesn't seem likely to be a head gasket at this stage, although peugeot dealers want to charge for looking at this. Also the car used to run at about 80 degrees, the guage now sits at about 70 (only just registering).
It has been suggested that it could be the oil cooler.
Any help would be appreciated. [8]

Hi, do the hdi engines have a heat exchanger type oil cooler or a proper oil cooler (like a radiator)?
If the former then these can be problematical as I found out once on a Golf GTI. The casting in the heat exchanger had gone porous causing the oil and water to mix. Strange how water is not contaminating the oil though, I would suspect this to be more likely head gasket. Hope I'm wrong though!!

As far as I can tell, it is a heat exchanger type of oil cooler.
The volumes of oil involved are very small as the sump is still full.
