A problem that has plagued my '83 944 for some time has finally been
solved. Those of you who have had water in the floor after a heavy
rain, have been told that it was probably a leaky battery tray, or
stopped up drain hoses from the sun roof, or leaky seals around the
rear hatch, or a leaky windshield.

After checking all of the commonly recognized leak sources and
several unnecessary "repairs" in an attempt to stop the floods, I
finally resorted to a using a large sheet of plastic and the garden
hose to isolate the problem. I quickly eliminated everything rearward
of the windshield.

Lowering the plastic sheet to the bottom of the windshield eliminated
that as a source. That left something inside the engine compartment.
The battery tray did not leak. Working my way across the firewall, I
came to the plastic cover/shield over the heater fan. That area
leaked like a drain! The sealant had deteriorated badly in the back
next to the firewall where it wasn't easily seen. I easily worked
the cover loose and re-sealed it with black silicone goop.

My 944's floor has remained bone-dry after several heavy rains.
Problem solved.

Think of it as "early preventative maintenance" :-)

Good write up, and thanks for sharing! You may have saved someone
else some un-necessary work.

Yup. Actually, all of these potential leak spots certainly benefited
from the attention they received.

Thanks for the <thumbs up>. Believe me, I was grinning from ear to
ear when I finally plugged the leak! I failed to mention that I took
the 944 to a Porsche shop and an independent mechanic, both of whom
failed to find the leak. That made my success all the sweeter! If I
can save someone else the trouble that I went to, so much the better.

Super duper detective work. My 83 was plagued with that problem too.
Everytime I thought it was fixed - it didn't leak, until the next rain storm
came and flooded it....

Hm...mine was dripping on me again yesterday...think I'll have a look.
Years ago it was because there were leaves that had gathered in there and
were blocking the drainage...we also thought it was the windshield but the
glazier figured it out....I'll give it a snoop now...

Water in rear seat thanks to a leak in the sunroof - has rotted the
material. I am damn annoyed - if only I'd spotted it sooner. Now I don't
only have the leak to fix, but am told that it's about £1000 ($2000US) to
get the seats reupholstered.

dave - for the 1000 pounds, you could easily buy a rear seat on ebay (mine
sold for $10), fly to the US, have one hell of a party, pick up the seat,
put a handle on it and call it luggage, and send it on home with you. Also,
are you really sure it's the sunroof and not the seal between the hatch
glass and the frame? I know you guys on the little island get a lot of
rain, but out here in the dry lands, the sunroof seal is rarely the cause
of a leak, it is almost always that the urethane has debonded from the
aluminum at hte top of the sunroof. If that is the problem, repair it
following the FAQ and BE SURE TO USE both primers recommended by 3M -
otherwise it won't work

Thanks for that - we're pretty sure it is the sunroof - we had one
helluva storm the other day (10mph max) and my girlfriend observed the
waterfall while I looked out for cars.

following up - the sunroof drains are subject to clogging - be sure they
work - all of them -
And, re seats - buy a seat from a wrecked car - look on US Ebay if the
prices are too extreme locally to you - if you find one at a fair price,
shipping will be under $200 - if you don't want to go the e-bay route, I've
had good luck with HoustonEuropean (they have a web site). I certainly
wouldn't pay $2000 for reupolstering a rear seat - I can sell you a whole
car for $3000 that is running and ready to go - here's a link to it
http://losangeles.craigslist.org/wst/car/365343347.html - and if you fly out
from the UK to pick it up in person, I'll even treat you to dinner or
something....... (who could refuse a deal like that? well...... :-)

Thanks for that - will check drains tomorrow.

Found a few seats on eBay - yet to find one that's not in a poor state in
the right colour - but it's not time to look yet anyway (not until leak
fixed).
