Default no oil pressure

ok this is now the second motor which i have went through. both of these motors lasted no longer than a week. 1 was a d16a6 the other a d15b7. i slapped my turbo on, which i believe to be the culprit. im using a standard tuner toys block T for the oil pressure sending unit and oil feed. with optional oil press guage tap. anyways the other motor spun a bearing and shreadded metal all into my oil pan. i cleaned it with parts cleaner and pressure washed all the stuff out. well both motors were ran n/a for a couple of days until i could get around to install all the piping and oil supply. well both times the oil light would come on and stay on then not far behind my car turns into a diesel, at least sounds like one. and i took the oil cap off and no oil spewing eveywhere. just loud valve ticking and bottom end nosie. so what is going on, why does the oil pump i guess keep going out.? im tired of pulling these motors in an out, its getting old. some one help me solve this problem for good. oh and both motors were around 100k miles and sat around for awhile. NEITHER MOTORS WERE primed. do u think that could do it. giv e me some insight

No prime is probably the reason. What assembly lube did you use?

That's probably the case, because a used motor still has oil in the mains and motor, even if you drain it, so being unprimed isn't what did it.

Sounds like you kept driving with no oil pressure. I've heard that that is not so good for engines.
