Where's the best place to put the sender for the oil temp. gauge on a normal rs turbo engine?

cheers

 

Try www.gaugeplace.com i've just got one of there OPOT sandwich plates for my series 2 and i am quite impressed with it. Gives you the option to fit upto 4 sensors or maybe plumb in an oil cooler. Good price and delivery was very good would defo reccomend them
