So ive been procrastinating for a while with my car and I finally took it to the shop to confirm the problem I had with the coolant and oil mixing. And yes its a cracked head. "V shape crack in one of the cylinders" Mechanic was surprised it never made any noises.
Nevertheless car needs a new engine. Worst timing too, just bought a house last week. So it will be sitting in my new garage for a while until i figure out a solution...
