Blue smoke I'm assuming? How do the plugs look? If you have access to a compression tester that would be a good start.

There's the valve stems seals which are what you have replaced. What jrzook is suggesting is the metal sleeve that the valve stem rides in has excessive wear which could also explain you oil consumption.

Is the blue smoke more when cold on initial startup or worse at high revs? The pistons rings/bores could also be excessively worn. A compression test won't give the full story. There's a few rings and the compression rings may be fine but the oil control ring may be worn or stuck.
How many kms are on the engine?

It dose go through a bit of oil that's what we are thinking now it must be oil rings so I think I might get one of those eBay rebuild kits what are they like do you know?
