your going to do this over a tea spoon of oil?

anything with a turbo will have blow by, its normal. unless your pushing out more than a gallon (high low mark) between your fuel interval or have actual on the ground leaking or visible leaking if not i wouldn't worry about it. honestly you could probably change your driving habit and the oil would go away. or just compare the amount collected between city to freeway miles ect. freeway will push more oil.

plus you dont even know if the HG will fix the issue. i would check the head and valves for any sort of "compression leaks before the hg and rings. obviously if your doing head work your doing a hg too but to just blindly decide to do one.. do a compression test before you pull the head lol but if thats the route you plan to go use MB stuff for the HG and head bolts because it will be the best made and most engineered/updated part. the bolts are defiantly torq to yield and pretty tiny at that too so i wouldn't even think about reusing them even if they are still with in spec for stretch. .
