318 with blow by

so i put my finger on the pcv valve hose, it does not suck it is a blowing that is does there is no vaccum at all on this hose, so if there should be i dont know whats going on. i changed out the pcv valve when i posted this, and it seemed to fix the oil going threw the tube, i thought but i just dumped the tube out full of oil once again. my oldest brother thinks and says that is how they run, but for some odd reason i dont buy it! im going to do a compression test here on thursday on it. is there a difference on where the pcv valve should be located on the cover, mine is driver rear side? should it be located in the front? i am lost.. i do have new valve covers to put on it, but i was going to do that next spring when i fix the oil pan leak, i dont know if maybe its the valve covers also, i dont know how much difference there are in them. they might have a small leak on them also.. so not sure how much that will play a part in the whole effect on this issue also. but i will do compression test and see what that shows... thank you for the insight.. to all...
