New 2L build case align bored and gallery plugs replaced with threaded plugs so i know everything's clean in there. New CB type 1 oil pump mod the fit Tp 4. Temporary oil pressure gage fitted, Valvoline VR-1 20W-50 oil and all bearings pre-lubed with assembly lube (the red stuff)
With my test rig I'm trying to make sure oil pressure observed before trying to fire the engine. Spark plugs pulled, so easy cranking. I've now cranked it over perhaps 30 revs so far and no pressure showing yet. I did not pre-fill oil filter (not sure why that's a bad idea) I pulled filter and there was ~ 1/4 full, so it seems oil's getting somewhere, but how long does it take to build pressure ???   |

Put the muffler on. Once the muffler is on you have the engine ready to be lifted into your car once the run in is done. Its also a lot easier on your ears.
Also, put the rest of your tins on. You don't want to run the engine for any length of time with out the tins in place, or you won't get enough pressure to cool the engine. Zach |
