without pulling pistons and crank graze busting is going to be an arse.

Flat edge across the block will identify an issue but then you are down to block stripdown and decking it at the machine shop. My Machine shop is not keen on this kind of activity on anything cast and iron, I guess it trashes the tools.

that said I would start easy, get valve guides and seals sorted while the head is off. Then check out the engine breather, if this is bunged up or not standard then it will over pressurise the crank case and blow oil mist back up past the rings and into combustion.

I would pull the lot and have it done properly. I made the mistake with the thunderbird engine of thinking just doing the heads would sort it. Now I have had to pull the lot and the engineering shop said straight away it needed a rebore. I had a gasket go like that on an old A series and even though it was only blowing for a week or so it buggered the block so check it very carefully. There is nothing more annoying than having to do a job twice.

No way am I taking it all out. The bottom end is fine as evidenced by the oil pressure and no noises for concern. There are acres of metal between the cylinders. I cleaned the crankcase breather last year as it is a maintenance activity. There did not look to be any valve stem seals fitted, this could have been a cause of the smoke but I will have to wait for what the machine shop say.

I can see both sides of that. And I know what I would (which only rhymes with should) do. Leave the bugger in.

No valve stem seals along with years and years of wear on the guides could well explain the smoke. Were stem seals ever an option or do you need something like the CVH type that are located by the spring?

If CVH ones fit get the ones from the turbo. They are located by the springs, the NA ones aren't and just slide up the valve stem in minutes.

early rover v8 had a rubber disc that fits on the valve stem then taps against the top of the guide. so useless that I don't bother.

If you are having new guides fitted the machine shop may well be able to fit a newer guide that allows for a modern pullover seal to be fitted

Valve stem seals are 'a thing' in the workshop manual; mentioning the valve spring can only be compressed 5mm when re-fitting the collets to prevent the seal coming off, so they must have been fitted from the factory. Or at least to later cars. Despite the occasional blue fog it never used much oil.

Aye, no American car yet, but there will soon be two other vehicles incoming! 1958 was my favourite model year for U.S. cars. I would love a '58 Cadillac Fleetwood Sixty Special.
