An NA rotary almost never "wears out". It usually dies suddenly from an overheat. Change the coolant & replace the thermostat with an OEM one every 12-18 months. For coolant use ethylene glycol that's safe for aluminum and distilled water, 50:50. Never ever use Dexcool, etc., etc. Inspect the hoses, fan belts (and other belts) regularly. Do all that and it should go to 350k+.
A distant 2nd on the cause of failure is sudden loss of oil. Never over/under tighten the drain plug. Replace the oil cooler lines if you get a leak.
Pull over immediately if the temp needle ever gets near/on H or if the oil pressure gauge hits zero or if the coolant/oil buzzer goes off.
