Thread: Too much crankcase pressure, novice engine builder

Tweet

Ken-about your 1957 Ford-------The 57's didn't have factory pcv system-they had a vent tube breather system----the mods done for smog probably removed/sealed that and then pressure would build up------and-----------the oil system-------especially 2 qts low-didn't have enough pressure to overcome the positive crankcase pressure to have oil flow to the crankshaft-----

It was only 2 quarts low after the dipstick blew out. Funny thing, Ca has been "fighting" smog since the early 60's and they still have smog. A guy I worked with at Douglas said "that as long as there is a smog commission we'll have smog". No truer words were ever spoken.
