In earlier, 1995, Range Rover, I installed an Edelbrock dual timing chain gear set, with no problems, and ran it on that engine rebuild for over 100,000 miles. So now for my 2004 Discovery 2, I am considering doing the same, because the dual chain stretches way less than a single chain set, BUT, I don't know if that dual chain/sprocket set will fit inside the front cover, that functions as housing for water pump, for oil pump gears, and at the same time, covers up the timing gear set. HAS ANYONE DONE THIS, USED A DUAL SET INSIDE THAT FRONT COVER, WILL IT FIT AND RUN FINE IN THE COVER? THANK IN ADVANCE.
