thx

You need a 180 deg. thermostat. Y blocks have a sludge build up problem, especially if mostly driven at slow speeds in city traffic. The 'road draft tube' system is not very efficient at low speeds so a 180 deg. thermostat helps the engine maintain operating temperature for less sludge formation. Your oil pressure is fine.
