I agree with this. Always split the case. I got a '79 vanagon type motor out of a wreck and yes it ran fine with good compression on all cylinders. I replaced the seals on everything including the pushrod tubes and happened to

look at the cam lobes through the ports. The cam was totally gone. Since these items are case hardened they have a distinctive erosion (yes I mean erosion) pattern once they are into the soft core. I shelved it in favour of another 1700 type IV core that was in better condition and could be rebuilt more cheaply.
