[C320-list] Lewmar port gasket replacement

[Jon Vez]

I would agree that the most likely source of your leaks are those horizontal
grey splits in the frame. I made the mistake of doing the gaskets on a
couple of the ports first--tricky is being kind and turned out to not be the
source of the leaks. I wrote up how I repaired those slits and that should
be somewhere in the archives. I ended up using 3M 4000UV because it comes in
black. Once done, it looks like it came from the factory. Use a syringe to
fill those gaps and once you get the hang of it, the job is quite
straightforward and much easier than messing with the lens gaskets...good
luck...

All four of the portlights on my 1999 320 were leaking when I purchased it.
The fix (which has been previously documented) turned out to be the
replacement of the gasket between the split aluminum frame. You need to take
off the plastic frame on the inside of the cabin portlights so that you can
see what's happening. The gasket needs to be picked out from the outside
with a dental pick or some such tool the shape of this gasket is like a
double S very complicated. Once the gasket is out you need to tape off the
edges of the gap between the frames and proceed to fill the gap with black
3M 4200( or other similar caulking). You can have someone on the inside to
indicate that the caulking is oozing through (I didn't and used a bit too
much caulking). I did this in 1999 and nary a sign  of a leak to this date;
from 10feet it looks like a factory job!
Good Luck
