[Fot] 1966 TR4a transmission help

[mhmolson at gmail.com]

Good morning, I have an issue with transmission oil leaking out of the three
o ring seals where the transmission selector shafts enter the top cover.
This only happens during high rpms. This is an overdrive unit.

Has anyone added additional venting to the top cover. I understand there is
possibly a small vent hole in the front however I have not looked at this
yet. I am also going to build a TR4 motor this winter and am looking for
direction and contacts for pistons, liners, and rods. I am good at
mechanical logistics, and I have built two strokes, I have also been around
engine builders and understand, however this will be my first real build.
Yes, I understand that certain things will be left to the pro's

Help appreciated

Matt
