I can do that for the start up knocking sound - it seems to come from the
left head- I have double checked the lash but haven't got round to removing
the flats from the adjusters so It could be done more accurately.

I didn't know that you weren't supposed to use that paper gasket, but it was
very thin. The end-float that I measured was below the specs in Haynes so I
figured it wouldn't do any harm. Should I take it out and do you really
think that such a small addition to the end float could cause this nasty
sound? Will it cause me further troubles down the line if this isn't the
problem now? Another thought I had was that maybe I didn't centre the fan
housing well enough and that was causing the fan to rub when the engine
warmed up and maybe the crank elongated a bit?
