Need help! Just replaced crankshaft in a 3046t, got it back together new rings and bearings etc. started cranking it to build up oil pressure and after about 15 seconds of cranking it fired off. This would be ok if I had fuel connected and ready but it showed no oil pressure and was running on oil! Rebuilt many larger engines and never encountered any like this! Looking for all the expert advice I can get!
