hey fellas.

I have a 1990 sw20 hardtop import, and with this torrential rain i have found there is a few leaks, mainly from the rear quater window area. i need to fix this urgently and i'm not sure what needs to be replaced to fix this problem. I cant upload photos atm but i will try for a later time. the majority of the water is getting through the rear vents next to the rear window

thanks

Would be good if you can post some pics. Usually the SWs tend to leak around the Targa seals, not where you describe. Otherwise some silicon may do the trick?

Yeah they can leak from  that rear vent.
Underneath is a flap that lets air out.
You should be able to see where it is leaking if you remove the triangular cover, but be careful not to break the mounting lugs.
 
 

found where some of the leaks are coming from. seems to be the top of the rear quarter windows. Somehow the drivers side carpet is soaked but i dont know how as I cant find any other leaks??

and it is a hardtop :P
 

Pull the trims around the windows and windscreen off and put silicone all around it. That will fix it.

I would use windscreen sealant and not any old silicon.

You can buy the proper sealant from Autobarn, from memory the name featured numbers.  It doesn't go hard, just forms a skin.

You'll probably have to find you have to remove those quarter windows and reglue them with the non-setting mastic.  I replaced my quarter windows and they leak when I high pressure wash the car.  I need to get a tube of butyl mastic and pull the windows and put a bit more in there...

The non-setting windscreen sealant is best but I did mine with ordinary bathroom silicon and got away with it. I loosened off the bolts that hold the window in place and pulled/scraped out all the old crappy sealant. I then pumped silicon in between the window and the frame. After it set, I tightened the bolts back down which compressed the silicon for a good solid seal. Did that over a year ago and it's still good.

perhaps roof and gutter sealant then. It's apparently better under UV
