To List; I feel that I am very lucky to know the DMC list, Thank you very much for telling advice, spending your important time, and showing great knowledge. I will work on this weekend (I want do right now but I have to work for eat) By the way, Volvo 760 and 780's engine,B280F, has a water-cooled oil cooler. I don't know why they add it even 10 HP extra engine If I compare B28F and B280F, (I know some change in both engine) Volvo must have the reason because if they save a production design $1, they can save a lot of money in mass production someone who add extra HP might be interested in the oil cooler. It is fit our engine with a little hard work. (I got most parts from Volvo 760 in a junk car for $120, if new oil cooler core, it costs more than $300 in Volvo) and it might be our engine life longer when we instal an oil cooler right.
