According to the Matey Matey website, in normal operation the oil temp of the 8v should not exceed 100 degrees, and the valver should not exceed 110 degrees. In reality my 16v runs between about 95 and 105 degrees.
Gibby - I was wondering what sort of temp I should be waiting for before thrapping it - I usually wait until about 90; it would be interesting to see what the oil companies recommend..
