I have a problem and a question , my car was running pretty good but i think my crankcase ventilation was pulling too much blow by when I had it connected to the back of my manifold so I changed it to go to my carb instead, I’am not sure why but it seems to idle and run a lot better this way. the problem is I only have 300 miles on the engine and I went to the gas station today and back home , parked it and now my rear main seal is leaking ? I read somewhere if you don’t have enough ventilation it could blow out your seal ? Has anyone heard of this ? I will post 2 pictures of before and after my switch.
