The passenger side on my car tends to leak even using the thicker gaskets. So I just did the old trick of 2 gaskets on it. And by the way I'm turning blue here also waiting on an answer about the Percy and Remflex gaskets.
That is funny, my pass side leaks much worse than the drivers also? I doubled up on the pass side and it is much better. Now I can hear one on the drivers side. I'm waiting for some testimonials too.
