Yes, it can. My 1993 had the oil pressure check valve stick open I think it was. The oil pressure shot up, blew the oil filter off, then dummped all the oil pressure due to there being no filter. Unfortunately, when this happened, the previous owner didn't shut the car down fast enough, and it took the motor with it. We replaced the pump and had it running fine when I bought it until we took it for it'* first test drive. 1 mile down the road it started knocking like an SOB. Yanked it and put a 28k motor and and she runs like a top.
Good luck with the car. Hopefully the new motor will get you up and running soon.
