[DeTomaso] Transmission viewing hole cover

The clutch assembly will have a lot of dead air except for immediately
at the assembly itself.  Heat would cause the air in the bell housing
to expand slightly so a small vent would be sufficient to relieve that
pressure.  Even with the access port fully sealed, there are a couple
of other small places for air to escape on my bell housing.

Maybe an enterprising vendor could build an adapter, hose and scoop to
attach to the access port?  I don't think it would do much but it
could satisfy some concerns.  Just not mine :)
