Hi Andy,
Just checking in before I go and make a stupid mistake...the thrust washer on the bottom of the oil pump drive shaft seems to have stayed in the crankcase recess when removing the shaft for inspection, its hard to see but I'm fairly confident it is in there. Although the washer seems to float about a fair bit left and right, is that correct?
When I refit the oil pump shaft it seems to locate easily enough but there is play left to right on the shaft (I guess this play is taken up when fitting the oil pump over the top)?

Still not finally located the leak so I want to reassemble correctly and see what happens..

Cheers for any input.
