General crankcase vent question
Hello all. I am in the process of reading and learning every night from you folks and am feeling more confident daily. So I was reading a few threads about crankcase ventilation and have a question. I have a 77 F250 highboy with 351m with some mods that PO's did (weber/carter carb & intake manifold)and I don't know if it is actually 351 or 400. Anyways, the passenger valve cover has an adaptor in the top with a hose that used to go to the air filter cover. I have an Edelbrock air cleaner and the hose that comes out of this passenger side valve cover has a length of all thread plugging it up. There is also what appears to be a slight leak at the rear main seal area....SO HERE IS THE QUESTION-Without the proper crankcase breather, will there potentially be enough pressure to cause a leak at the rear main seal?
If so, would replacing this plugged up hose with a breather help the situation. Thanks in advance.
