HELP! No oil pressure in assembled 4G32b
Posted: Mon Sep 18, 2017 8:07 pm
Hi everyone
I just replaced the front and rear oil seals in my engine. After re-assembly, I cranked the engine for up to 25 secs at a time to circulate the oil before connecting fuel and spark -- but no oil pressure, and the filter is empty. Clearly the oil pump isn't working. Does a trochoid pump need to be primed? I reassembled the pump with some oil on the surfaces and the marks facing into the case, as per the Gregory's manual, with a new rubber gasket. I also found a manual online that said the marks need to be aligned, but I couldn't see how that should be done, and it was after I finished assembly.
Any ideas? I will pull the oil pump tomorrow, but I'm not sure what else to do.
Cheers
Mick
