Just bought 95 LS

Ok I finally got a monte. I have a 95 LS with 130k on body 104K on engine. I was told that the car ran to a store and never would start. No lights came on or overheated simply did nothing. Towed it to the mechanic and he said it had low oil pressure and found metal in the oil. I too found metal in the oil. One speck in it and it aluminum???? What aluminum is inside that would shear off? It tries to fire but doesnt. Am I better to replace engine or try to fix this one? Are there common problems that cause this?

OK I have looked over the car a little more. The paper from the shop said they drained the oil and found alot of metal in it.. I checked the oil its old oil not new as they said but pretty clean. And its really tryin to start acts like not getting fuel so we will try more tomorrow any suggestions please let me know.

pull front valve cover and watch all rocker arms while cranking, these 3100's are good at breaking camshafts. let me know
