Not sure if someone has said this...but when you line hone the mains, the pan end seals are...too long and like to buckle and leak...

It all depends on how much was honed out, usually only .005 or so but who knows what they did, and how many times.

If you see the seal bulging out just a hair...thats a good indicator.

You know now that you said that the front main in the middle where the oil is leaking the rubber is pushed outward just a tad and the paint isn't on that part of the seal anymore. Right at first the rear started leaking just enough that when I drove it oil would coat the bottom of the dust shield on the trans. I asked the motor builder about it and he told me to tighten up the pan bolts so i have a little at a time. Than I notice another oil spot on the garage floor and sure enough the front started leaking and just like you said it looks just like the middle of the seal has a slight bulge where the paint is gone and you can see the blue ATV sealer showing. It seams to leak more when the motor is running, because it is right behind the fan and it blows it all over the front of the oil pan. I looked up the torque value of the oil pan and it says to torque them to 15 ft lb which translates to 180 inch lb. I have a inch lb torque wrench but I haven't gone that route yet to check them with a torque wrench. So what is the answer if the rubber gaskets are to long? Can you trim them down? or use alot of sealant on the ends? My plan is to try this winter and take the oil pan off and change the gasket and try a Felpro(rubberized) or a Milodon (crush proof) Gaskets. Sorry for the long post.
