Ford V8 sump- with road draft tube and Hydrovent
Hi Ron,
As Lynn mentioned there were two types of sumps: those with a road draft tube and those without.
Keith Webb posted a while back on Canadian Military Vehicles Facebook page, a WW2 D.M.E Technical Instruction regarding the fitting of the Hydrovent. Perhaps he can reproduce it here too if he reads this. Hydrovent was a name used by Fram for the PCV system.
It mentioned those sumps fitted with a road draft tube and the Hydrovent need to have the tube blocked off with a thin shim for the system to function properly.
I have two 1946 engines with road draft tubes, but I am running the Hydrovent on one of them, so I fabricated a block-off shim as per the Instruction. Even those two sumps are different. One has a smaller drain plug and one piece (car?). The other has a larger plug and a removable lower section at the flywheel (truck?) which is the one that I am using on my truck.
Hope this is of some interest.
Cheers,
