Thanks David,

I wasn't sure just didn't want to kill and engine over something so small.

obviously the oil pressure into the tubes is not that much I know it just pours onto the cams, as I've seen it as I cranked it by hand.

I thought however, as there is a direct connection to the bearings, it may need to be injected in under pressure.

So if they slide up and down the tube without to much resistance this should be ok?
I was a bit alarmed that if you hold the tube at one end the other end cap just fell off.

Thanks again
