<VV> Water ingress

### The plot thickens - I took the front cowl panel off and all the 
holes under it had been blanked off with bits of stiff plastic sheet 
held on with silicone sealer. I ripped them off & played the hose on 
that area, and water is sort of dribbling out of the front of the rocker 
panels. Doesn't look nearly enough flow to me for a drain hole though. I 
tried to get a knife blade up there but it didn't want to play. I'll try 
with an air line tomorrow - if that doesn't work I guess I'd be best off 
drilling a hole up into the rocker panel where the drain is? The car is 
facing downhill on my drive at the moment, so after I've sorted the 
front end out I'll turn the car round & focus on the rear.
