Kenworth sunroof leaks

My sunroof leaks. I'm just wondering are these sunroofs still prone to leakage even if there's a brand new seal installed? Or will a new seal not leak at all for several more years? I'm debating spending the money on a new seal from KW versus just siliconing the thing sealed shut permanently. It's a 15 year old truck and I just want to stop the leaking. Whether or not the sunroof opens really doesn't matter one way or another.

 

Thanks everybody. That seems worth a try with the petroleum jelly. I'll see what it does. I'd be surprised though. Years ago it used to just drip very little thru a truck wash or in a really hard downpour. But anymore just a little rain shower and it drips in pretty good. Going thru a truck wash it actually pours in like crazy.

I said I don't care if it doesn't open but honestly I'd hate it if it was jerry rigged up like that. At least with silicone that could be scraped away and fixed right at another time. I definitely don't want a permanent epoxy poured on it lol!

I'll probably buy a new seal if vaseline doesn't fix the old one. I was more curious if these sunroofss were known for or maybe notorious for leaking even when these trucks were new from the factory? Just seems like if that's the case spending $150 or whatever really high price Kenworth charges wouldn't be worth it.

 

I did a little homework on this. Turns out the company that makes these particular sunroofs that are in Kenworths discontinued the particular model of sunroof many years ago. The company is Inalfa and the model # of the sunroof is F700. Replacement parts are impossible to come by. So if Vaseline doesn't do the trick swelling up the original seal I'll be sealing it up with silicone. I did see where someone recommended liquid electrical tape brushed on the seal building it up some, allow that to dry good, then close the window - might seal it. I dunno. Never used any liquid tape before.

 

First question to ask is did you check with Kenworth? If it's the same type sunroof as what was in my older 2003 T600 then you can't get it or parts for it. They quit making that particular type of sunroof about 10 or more years ago. Your only option is to silicone it around the outside so it won't leak anymore. I know that sucks but it is what it is.
