Thanks dimitri, ill look into the way your suggesting.
Josh(young) has been helping me alot with this motor and has been basically telling what needs to be done to get it fixed, he seems to think the crank will be fine to reuse, but ill do my best to check this before hand, i spose the worst case if it is rooted the machinist will just turn me around and say get a new crank...

But yer new second hand rods and crank might work out cheaper... will see how i go
