In Reply to: 61 WM300 VACUME BUILD UP IN CRANKCASE posted by Bob Stopka on Saturday, July 26, 2003 at 9:06AM :
A friend emailed me off line and said his tube from the manifold to the block has a valve you can screw in and out. He never played with it, from what I see, sounds like his valve will adjust the vacume pull in
the crank case. Anyone else have a set up like this ? My 61 doed not have the valve, only the pipe.
