Good evening, i have two doubts about GEMS oil cooling system, hope somebody knows the answer.
1) which is the real task of oil cooler bypass spring valve fitted in timing cover?Is this valve really so sensible to detect oil density, so when oil is cold (thicker) the valve open bypassing oil cooler and helping oil heating? Or the valve is just a safety item, that open in case of poor flow in oil cooler?
2) i noticed that oil input and output in timing cover are really small, fittings diameter is less than 9 mm (very restrictive) and rubber pipes just 1/2". There are a specific reason why land rover choosed to use such a small lines for a low pressure/high volume oil circuit like the GEMS?
