Well I have been noticing a loss of coolant have added dye to coolant to detect leak nothing was found. This has been going on for months now adding coolant I have performed 2 oil changes since noticing issue. I just changed my oil today and noticed alot of gunk(first time ever) I knew about castech head issue removed my valve covers and found what was almost like caramel orange in color. Checked for casting mark and the heads are indeed castech. This is a known issue what are my course of actions to take?.
