Should I Get 2nd Opinion?

What is your question?

Had clicking sound near belts when car starts when driven at low speed --but not always maybe 2 days. On way to AAA mechanic it stalled THEN the engine light went on. They said it has low compression-valves, piston etc..need new engine. They started it briefly but then loud noise and engine stopped. Sound right?-New engine? Or should I get 2nd opinion. Have been using this shop for a while. No leaks. No low fluids. No discolored fluids. No smoke. Has been regularly serviced.

What makes this problem better or worse?

Nothing it is not every time car starts-clicking sound
