Hi, I've been thinking of adding an oil cooler to my R380 (TD5) these are not fitted to Disco TD5 UK models but are in those sold in ROW. I thought it may be useful for summer driving in Spain. Ashcroft Transmissions sell them for £250 (+VAT)

Question: If I got hold of a R380 oil cooler pipe take off bracket from a V12 is there any reason why I couldnt just build an oil cooler much much cheaper from bits on fleabay? Would there be any considerations that I would need to take account of?

Thanks
