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 ???   |

Cam break in. 1.7-1.8 H/E's, yes want to run the engine on my little test rig for cam break-in cycle. Will then re-torque heads and check valve clearance before loading into car. Will have 40 Dell's and my fuel system will be an elevated tank to provide 3 psi Not sure if I'll ned to add the muffler, time will tell ! |
