Hello everyone,,

I topped up my coolant from Min to Max which is roughly 14ozs or so. Thought it was odd but not unheard of and figured it may not have been topped since car was delivered. I am the 2nd owner of the vehicle for historical reasons and i purchased from a private seller in Oct of 15 with 14,000 mi. I just checked the coolant again yesterday cold of course and just above the Min line again. I topped up again which needed about 14ozs. I have never noticed milky oil or oil in expansion tank. I dipped a piece of paper towel in exp. tank and comes out perfectly blue. There were a few tiny specs of blk deposits but chalked that up to fine debris from the coolant system. I have not pulled plugs yet but planned to replace https://100001.onl/ https://1921681254.mx/ https://happymod.site/ them soon anyhow. I am running an ER catless D.P. And armytrix exhaust so what smoke/moisture is coming out doesn't seem out of place. Im thinking something is leaking in the engine bay but have never noticed anything. I want to avoid stripping parts off my car to take to the dealer. I plan to open the exp. tank lid and run the car looking for bubbles in the tank but dont suspect i will find any. I have done leak downs and compression checks before but this car seems a bit more complex. Any advise would be greatly appreciated. FYI. I do not drive the car very often the first top up was prob at 18,000 mi and now im close to 22,000. any advise would be greatly appreciated.

What engine ? On b58 it seems to be a known issue where coolant is dissapearing. I personally had to top off mine couple of times but can't find any leaks so far.
