The road draft tube has an aluminium plug with an "O" ring on it pushed is
and secured with a small screw from the back.
Yes there has been a significant decrease in oil consumption, there is no
longer a stale oil smell in the car and oil drips are now only 1 or 2 each
time I stop.

Looks like a clean install to me (I like the 'aftermarket' heat
shield; I have one made for a 100M on the shelf if I do get around
to installing PCV on my BN2). How did you seal up the road draft
tube? Any noticeable effect on oil consumption/drips?).<br>
