Guest imported_MikeWilliamsUK Posted September 21, 2003 Share Posted September 21, 2003 My '38 Zephyr has three outlets from the LH rear of the block, one facing upwards for the oil pressure gauge, and two facing outwards. Which is the flow from the oil pump and which is the return to it? I assume the flow goes to the very bottom of the filter canister and the return from part way up the canister, so as not to collect the sludge?Thanks,Mike Williams Link to comment Share on other sites More sharing options...
DizzyDale Posted September 21, 2003 Share Posted September 21, 2003 Dear Mike.I have to believe the oil goes into the canister at the top and exits out the bottom.Oil passes through the filter on the way down,gravity does most of the work,do not believe there is enough pressure to work any other way.diz <img src="http://www.aaca.org/ubbthreads/images/graemlins/smile.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest imported_MikeWilliamsUK Posted September 21, 2003 Share Posted September 21, 2003 Thanks diz, that's solved half the problem (and proved me wrong!). Now, which hole in the block is the flow and which the return?Mike Link to comment Share on other sites More sharing options...
Guest imported_V12Bill Posted September 21, 2003 Share Posted September 21, 2003 The verticle hole in the back of the block is the preasure line that leads to the oil preasure sending unit and the oil filter cannister. The lead from the bottom of the cannister goes to the forward, lateral hole in the back of the block. The third lateral hole to the rear is plugged. I think there are some static oil preasure tests that are done using this hole. There is oil preasure in the return line ffrom the oil filter.
