Synthetic Oil = Rebuild Motor!!! OHH NO

Ok, I'm going to go ahead and explain why running synthetic leaks like it does. Synthetic oil is man made and all the molucules are made the same meaning that they are all the same size, verse a regular conventional oil where all the molucules are different sizes. So if you are running conventional and it leaks just a little, only a few of the same type of molucules are leaking out and the rest won't, but if you switch to sythetic, and one fits threw and leaks then they all will due to the fact that they are all the same. I change oil for a living and picked this up along the way. So if you switch back like you did then you should be back to normal. However one thing that I would recommend is a type of engine sealer. How this works is, it's added in with the oil and it heats up and when it contacts cork gasket,ect... of any kind and hits the air where it's leaking it expands, and undrys the gasket to some measures which helps out to some extent.
