Why does the blocked screen cause runaway? Does it pressureize the block and
blow oil past rings, and past valve stem seals?
Another cure if runaway is caused by blowby, is to add a fitting to the block
off plate next to the vacuum pump. Then the crankvent can run down from
valve cover to a tee at the block and then up to the intake. It has the effect of
draining excess blowby oil back to the block. It also makes an easier time
for the oil to drain from the head, as it isn't fighting the blowby gasses
coming up the oil drain holes. My TD had a fair amount of oil in the intake, and
since rerouting the crank vent there is virtually none.
