check for oil pressure w/o gauge?
I just got done putting the my 22r back together ( cracked head and blown HG) and I want to make sure I have adequate oil pressure before I go ahead and fire it up. Is there a way w/o hooking up a mechanical oil pressure gauge because I can't get the sensor off. I have the ign wire disconnected from the distributor so the engine doesn't actually start. Will the oil light (bottom left in gauge) go off when cranking if there is good pressure?
Thanks

the light will not turn off until it starts. You are doing any good by cranking it like that either. Just run it, give it a few seconds to build pressure... If it doesn't turn it off and find the problem. The engine is without oil pressure for a few seconds after every oil change, just make sure it isn't for a long time.

NEVER NEVER NEVER start the engine before you have good oil pressure after a rebuild. Most engine damage is done in the first 3-5 seconds after starting, on any day, and thats on a normal engine. Imagine the damage you are doing to an engine that was just rebuilt. Just do as I outlined above, and you will be fine.

With older domestic engines, you can prime the oil pump with a drill and an extension through the distributor opening...too bad the toyotas are run off the crank.
