I have fixed the intermittent oil alarm in 2.1 models many many times.
It was never due to actual engine problems. I'm sure it happens, as you
say yours did, but I have never seen it. I did not say to ignore the
problem and drive around. He is already doing some of that so he will
have to live with any consequences. There are possible causes that may
lead to serious damage if ignored. Testing for an electrical cause is
simple and straight forward. Most any owner can do it without purchasing
any test equipment or removing parts to gain access to the pressure switch.
