33Rock Posted April 7, 2014 Share Posted April 7, 2014 All - I have a '33 Rockne with the stock Flathead-6. I ran it for a couple if minutes for the first time yesterday and it ran good. Unfortunately the oil gauge didn't register any pressure (not sure if it works). Does anyone have a trick to verify the oil pump working drawing oil to the engine?? Has anyone experienced problems with the oil pump not drawing oil after a rebuild? It has 6 quarts of 30wt oil in it. :confused: Link to comment Share on other sites More sharing options...
rbk Posted April 8, 2014 Share Posted April 8, 2014 Put a pressure gauge directly on the oil pump.There should be a 1/8" NPT pipe plug.Maybe the oil pump has air in the circuit.Robert Kapteyn Link to comment Share on other sites More sharing options...
Guest GeorgeCagle Posted April 9, 2014 Share Posted April 9, 2014 When I rebuilt the engine in my '37 I had the same problem. My dad told me to pack the oil pump with Vaseline. That primed the pump and it dissolves into the oil as it gets warm. Link to comment Share on other sites More sharing options...
starlightcoupe Posted April 9, 2014 Share Posted April 9, 2014 ... pack the oil pump with Vaseline. Same result of using Lubriplate assembly lube when rebuilding. Link to comment Share on other sites More sharing options...
Guest R L Elder Posted April 9, 2014 Share Posted April 9, 2014 Hi when I rebuild any thing I coat all moving parts with Lucis eng. oil supplement pistons, cam shaft, rod & main , oil pump exct. it will stay in place sow you will never have a dry start up p/s I never use lubriplate as it has a tendency to harden after time Link to comment Share on other sites More sharing options...
Thoffs Posted April 9, 2014 Share Posted April 9, 2014 I had the same problem on my 1933 Rockne Model 10 just a couple of weeks ago, could not get any oil pressure. First I blew air in my gauge to make sure it was working. I put an extra quart of oil in to make sure the pickup tube was buried in oil and the Napa dealer told me to pack the oil pump with lithium grease and after a little cranking I got about fifth-teen lbs. of oil pressure. If your timing is right do not remove the pump, just take three bolts out of the cover and rotate cover to expose the gears and then pack it as best you can. Good Luck!

Guest R L Elder Posted April 10, 2014 Share Posted April 10, 2014 If you can find a pressure pre-lube pot you can hook it to the pressure port on the block and force oil back in the engine it will prime the pump most engine rebuild shops have one Link to comment Share on other sites More sharing options...
Dave_Pink Posted April 10, 2014 Share Posted April 10, 2014 I simply removed the gauge line fitting from the pump then used an oil can to fill the pump with oil. replaced the fitting then fired her up. Problem fixed. Link to comment Share on other sites More sharing options...
33Rock Posted April 11, 2014 Author Share Posted April 11, 2014 Thanks everyone for the help! I opened the oil pump and it was dry as a bone. My plan will be to pack the gears with grease or assembly lube and then try to fill the oil passages with oil. I will work on it this weekend and let you know!
