In Reply to: 61 WM300 VACUME BUILD UP IN CRANKCASE posted by Bob Stopka on Saturday, July 26, 2003 at 9:06AM :
No pcv valve that I know of. Just a hard threaded pipe from the manifold to the passenger side rear of the block, where on the WWII Dodges the pipe for crank case ventilation would extend down to dump it into the atmosphere. On the drivers side there is just a rubber hose connected to
nipple on the oil fill tube. It runs back over to the oil filter and dumps the crankcase fumes back into the oil bath air filter. Could really use some help understanding why there was so much vacume
from the manifold sucking on the crank case
until we restricted the pipe.
