Don't you have a vented oil filler cap on your TR4?  If there is excessive
crankcase pressure, this should handle it easily without have to add the
vent from the TR3, which can be another source of oil leaks unto itself.

My TR4 has both the breather cap and the block vent. I thought that while
the cap allows pressure to escape from the head, the position of the vent
tube 'out in the wind' was to draw gases from the crankcase through some
sort of pressure drop at the end of the tube as the car moves. I may be
wrong.
