I have been semi diagnosed with a rear main seal leak. I randomly checked my oil the other day to make sure it was still full and at the tip of the dipstick was a yellow gunk. No more than 2mm worth. I wiped it off and checked again and there it was. Did maybe 4 times and then it stopped. It had a Dijon mustard type color and viscosity. My dad said it may be water. Other things I have read is extreme temp changes can cause this. And in Texas we have had a crazy Winter. Anyone else experience this and should I be concerned? Thanks.
