Hi,
just took off my cams for valve adjustment. Noted the location of the cam caps meticulously. For inlet cam number 1 to 5 from back to front (of car) and for exhaust cam number 6 to 10 from front to rear (of car).
In Miles Wilkins Twin Cam Engine book is a picture (page 88 top), where one can see the sequence of the exhaust cam caps. It?s the same as on my engine.
In my Original Lotus Workshop manual (section E pg 14 top ) the numbering sequence for the exhaust cam caps ist the other way, i.e. number 6 starts at the back an number 10 ends at the front near to the timing housing.
As I know it?s very important to assemble it the same way it has been line bored once I?m a bit confused. Which is correct? Or did the numbering sequence change at some point?
My cam bearing caps are also different fron the diagram in the shop manual. But I match the number stamped on the bearing cap with the number stamped on the head, and I disregard the manual in this case. It seems that even the factory had a tendency to ignore the manual when it was expedient.
