Can't believe you guys diss FIPG that easily. On my 3B for the bj70 toyota doesn't even list a cork gasket any more. It's all FIPG. I *could* use a bj42 3b gasket but it goes to show if toyota is fine with it I cerntainly would too. Most of the 3B guys all use FIPG now. I replaced my F cork gasket a couple weeks ago and Like robbie said the corners are a PITA and need sealant. I can't tell if mine is still leaking or not from the pan as it's probably leaking from the side cover. In my experience if I had to do it ovr again I'd use FIPG vs the cork esp on a pan or side cover where they warp of distort easily.
See you on the trail
