[QUOTE="Marc Martello, post: 133119, member: 23740"] If you are blowing out the dipstick, then you have a fair bit of crank case pressure, I would say the rings are gone, with the head off what are the condition of the bores, are they scored, is there a lip at the top of the bore ?. If you are having trouble starting and there is heaps of white smoke during start up, you should check the injectors, they maybe dribbling, the excess fuel at low revs will wash the bores of lubricating oil this will cause premature wear of the piston rings causing blow by.
