You need a second and maybe a third opinion as to why you have no compression on #4 cylinder. There are a few simple reasons why you could have no compression and it does not necessarily mean you need a new engine. You need to get from an unknown to a known before you start writing a big check.

Have a leak down test done on #4 cylinder to hear where the air is going. If you are lucky it could be stuck or burnt valve. Since you are not overheating, the problem is probably not a blown head gasket. You might have the mechanic just check the clearances on the valves for cylinder #4 to make sure one has not closed up.

The blinking engine light is telling you that a cylinder is not contributing its share to the power output. The engine computer is warning you that further operation could damage the catalytic converter and possibly start a fire near the CC.
