Re: [C320-list] C320-list Digest, Vol 4925, Issue 1, Port Light Gasket Replacement

[LambersvanDorp via C320-list]

Hi Jeff, when your portlight Alu. frame has on the outside 2 joints that are filled with grey sealant, you first might cut and scratch that out and replace it with new sealant. Much less work, and for our C320 (1999) that was THE solution! No more leaking. If it doesn’t stop the leaking, you can still change the black gaskets, but good chance it’s just those grey sealants!
