If you are going to silicon up the windscreen doing the lower half is not enough, you have to do it all around the screen on both sides of the chrome finisher. Also the recesses have to be very clean and very dry before you do it

My local privateer windscreen fitter showed me the trick using BLACK silicon. very neat too.

other points of entry are

Corrosion behind the pedal supports area behind the sound deadening stuff, loads of rust here due to brake fluid overflowing and stripping the paint, and moisture retained by the sound insulation - you just gorra strip it off to find the problem.

There is a drain hole from the bottom of the air intake area into the rear of the engine bay that is covered by a small rubber flap. The drain hole gets blocked with debris and water entering the air intake area spills over into the interior by some unknown path.

Depending upon the attitude/position/routing of some cables (eg cruise control) or vacuum pipes (eg AirCon heater control) from the engine bay into the interior via the bulkhead water from a rainstorm can creep or run down the cables/tubes through the grommets and into the interior.

The sun roof drains at the front are supposed to exit into an area of the sill from where the water can exit to the outside via a drain hole. The rubber tubes can be dislodged during uninformed maintenance and route water into the car interior.

Just above the window at the front edge of the roof is a seam that can rust out and allow water into the A-post. from there it is possible for it to get inside the car depending upon how it finds the downward route.

Good Luck - loads of brand new stuff on my website.

Drill a hole in the bottom most corner of the footwell

The water will then have an escape route

Unless it is a daily driver - how often would you have it in the rain?

thanks ramon will look into all that,she's parked outside all the time ian so she's always battling against the eliments,same as me when i'm working on her ,thank guys for your interest

that's a pitty but really an escape route for water is not too bad an idea

In the GT40 it rains inside the car in the wet and we certainly have drains! - Yes it is better to stop it getting in but these were never designed to seal so we make do as we can!

In the interim Get a roll of cling film (Tesco cheep an nasty for 40p a roll works well) and cover your widscreen and surrounds when you are leaving it in the rain - will stop any water until you find the cause.

cheers
Ian
