Have had a coolant leak for awhile now, it has been puking out the degas bottle but has not been over heating. my oil looks fine an theirs no noticable rise in my oil level. Pulled my egr valve awhile back it looked dry but the bottom of my intake looked a little damp. and i have looked everywhere for more coolant leaks and cant find any? one day my coolant level will be over the minimum mark and the next my tank will be dry.. it fluctuates quite a bit. where is my colant going?
