Leaks, leaks and more leaks

[nick9one1]

After the downpour we've been experiencing here over the last few days I've discovered a few leaks!
I've got a very very wet offside rear footwell, and a pool in both boot cubbyholes.

I think both rear hatch pin lock seals are leaking... water running over the rear light plastic covers. (£20 a side!!)
The drivers rear sunroof pipe just seems to dangle in the boot cubby hole and is too big to fit through.
The front plastic shelding under the wipers is all cracked (I've heard this can cause leaks?!).
The rear hatch is "de-bonding" from the sealent at the top corners.

So far I've blown down the rear sunroof pipes with an airline - no blockages anymore! I couldnt see the fronts in the dark. Do I need to remove the sunroof to access them?
Iive also used the airline down the short tubes from the rear hatch pins, and those are clear .

Any other suggestions for the leaks?

Be careful with blowing compressed air down these tubes as they can often be blown off of their internal mounting points, hence making the leaks even worse [] Try pushing down a nylon wire like those found in a garden strimmer. When it's stopped raining trying pouring a small amount of water down each of the 4 sunroof drains and see if water appears under the car.

Thanks, I may try that tonight if it stays dry!

Inside the engine bay behind the bulkhead where the heater motor fastens, under the cracked plastic can leak directly onto the front mats if this are gets full of leaves and the water level builds up, or if someone (like my car) leaves a bolt out of the heater fan motor mount where it fixes to the engine bay.

...and I just discovered that my battery tray is rotten-disguised with poor quality filling and underseal...[:'(]
Oh well, in Spring I will strip it all out and weld it up properly....it will just have to leak until then! (Not too bad luckily!)

I found recently that the rear wing under the battery tray is completely rotted out (very well hidden by the plastic aero-thing on the outside). Also there is a little puddle that forms on the other side which is starting the same process...
Cleaned out and cavity waxed for now... needs a proper welded repair section soon

After some investigation today, I discovered Its the sunroof that's leaking. I believe I need a new inner seal as it looks like its running through that.

As it looked like it had been leaking for some time I decided to remove the carpets and seats. What an awful job!!! I managed to get the carpets out, but left everything else intact.
I cant believe how poor quality the interior on the 944 is. I think you would be very lucky to remove the headlining or rear quarter trim without tearing the incredibly thin vinyl.
I used to own a 1990 205 Gti 1.9 and the interior on that was much better made!

might be worth checking the door seal strips. Water entering the gap between the top of the doors and the roof can track round the rubber door seal strips and get inside the fixing channels of the door strips where they press onto the flanges . Where the seal strips change direction about half way down the sides of the door opening, water can get inside the channel and around the door flanges .

I've also had water get inside my passenger door and slosh into the footwell on heavy braking. It surged along the bottom of the door and between the door and door card.

thanks,

The wate sems to pool mainly in the rear passenger footwell.
I can definitely see the sunroof leaking, so I know that needs fixing. If it still leaks I'll look at other possibilities.

Ive just ordered some rubber U channel http://www.sealsdirect.co.uk/shopping.asp?intDepartmentId=3
4 meters of item U46, alone with some black gasket sealer.

Its slightly taller than the OE stuff - 10mm instead of 7. So hopefully It will seal better.
