Oh dear,i put all the lifters on a tray so i could clean out the rocker arms and bloody knocked the tray and they all scattered onto a really dusty sandy ground,I had a 94 ed sitting around so thought bugger it and used the lifters out of that.I put them all in and reassembled everything and man the whole engine shakes and runs rough as hell,are the lifters different sizes in different e series fords? and make it run like crap if not the right specific size?,man i feel like an idiot at the moment,any help is really appreciated.
