After trying in vain to get the white FelPro seals to hold (twice). (8BA engine). I finally Googled Felpro to get any info I could. On their web site they said do NOT presoak the rope seals as the fibers in them expand when they soak up oil. If presoaked they will not compress in the groove as they should and a leak will result. Install them dry and put a few drops of oil on them before you install the oil pan. As they soak up oil they will expand and seal. This is their recommendation. I tried it. 3000 miles and no leaks!!
