And possibly wrong seal, too deep.
Kinda afraid to start it like this,as i would think have oil flying all over the place or water getting down in the oil pan and doing any damage as it takes a few minutes to start the noise, I still plan on changing the oil anyhow afterwards but just being careful! As looking at this Pic it looks like the bottom of seal has a little shine to it also,so it might of been hitting it also!
