Oil and cracks......
Around our area 10 or 20 or 30 non-detergent oil is readily available from farm tractor shops..... stock item for all the old tractor being used.... they claim it leaks less than the detergent stuff.
Phil no doubt that a good functioning PCV system would reduce a lot of deposits....also the fact that when you do run them they are very quickly at there proper operating temperature with the low gearing and tight engine compartment.
On repairing a crack and having it done by a competent machine shop..... I don't think Alex has priced the hourly rates they charge recently ($100 + -)..... Welding the crack, having the head pressure tested and magnafluxed and machining the valve area and installing a new valve seat...... may be cheaper to find another head ........ there is not much market demand for old 216 heads and full engines are usually less than $250...... shipping is the killer.
Offer still stands for parts.....
