to check. Is there fuel in your oil? As in, you have mostly fuel mix leaking from your rear main seal? I have had a Spica dump so much fuel into the pan that I could no longer call it an 'oil' pan
. With that , there was fuel/oil mix pouring from every seal, including the mains. On a good note, once the Spica pump was replaced and the oil changed, the seals dried up and quit leaking...
