Scuttle : big steel gutter.. under windscreen..where the wipermotor lives.
So..
At rear of engine ..hanging down 3"/75mm
there are two flat looking black rubbery
plastic devices.
Give them a wriggle..
If you squeeze the broad edges.. they open out to form a tube.
These can build up lots of leaves and debris.. so rainwater cannot escape
Should really be part of the quick monthly checks.
Tyre tread. Wiper blades. Etc
I would post pics.. but the puntos outside are mk2
My grandes are 2000 miles away
