Thankyou Colin mate this is what I thought, reason why I asked there's a engine guide on here http://www.ukstarletowners.com/topic/58187-how-to-build-a-forged-5efte-engine-step-by-step-guide/ And I understand it's for a build a forged but in the built his put "Next is to put the main caps on to hold the crank in place, these also need bearings put into them, there are 5 of of them and they are numbered 1-5, again cover the outside in oil once fitted.. It is very important you put these on the correct way and in the correct sequence. You will notice that each one has a number on the top and also a small peg in the middle to indicate the direction it should go. Number 1 starts on the clutch/flywheel side with the peg facing the timing belt and then 2,3,4,5 all follow the same pointing towards the timing belt side with those pegs." If number 1 cap starts on the cambelt side and NOT the flywheel side this is very misleading to people
