I finally got around to fixing the oil
on my Universal M18. Unfortunately, I now have an alarm
ringing continously. The oil
pressure switch is buried under the exhaust
manifold/cooling reservior and I can't get it out without quite a bit of disassembly. I have a few questions:
1) Would it be likely that the oil pressure switch is dead after 20 years?
2) If the oil pump is not pumping properly, would the engine
behave weirdly? I have't notice anything out of the norm.
3) Assuming the oil pressure is low, and that this problem has been going on for a long time, is it safe to assume the engine
might be in serious trouble?
I guess I'm trying to gauge whether or not I've got to get this problem fixed immediately or it it just the oil pressure switch? Any educated guesses?
