Erm any help much appreciated, but I fear I may already know the answer. I have a 90 converted to a discovery 200tdi, and it seems as tho my coolant is pressurising, although it is running at a steady 90ish degrees. It's fine under normal driving but if pushing hard it will force coolant...

Hi just a quick hello and introduction, I am from nottingham and Been into cars for years but after buying a discovery I have been bitten by the bug and bought a 90 to go with it (pics to follow) The discovery is used as our everyday/tow car and the 90 is a bit of a toy/project for me...
