[QUOTE="Hilly_70, post: 615129, member: 4142"] Quick question for you engine guys here .. Ok .. slowly building an engine back up and just fitting crank / distributor drive and Cam.. Lower crank into case half holding 1 and 2 rods .. (so 1 is essentially TDC) My 2 marks on the Cam drive sprocket are 90 degrees from the Cam meeting point for the dots .. Therefore I need to turn my crank and move number 1 rod away from TDC to align the dot on the cam between the 2 on the crank drive.. So when fitted, the 3 dots are aligned in a triangle (1 on Cam between 2 on crank drive) and the Distributor drive is in and the rotor is pointing to the mark on the distributor casing and both towards the fuel pump stud. At this point rod 1 is no longer TDC? Does this sound correct? The book suggested No 1 should still be TDC when all the other alignments are complete? Thanks Chaps Hilly [/QUOTE]
