Did you replace the oil pressure switch unit? Section 12 of the service manual has tests for the switch

1. check oil level

2. Remove oil pressure switch.

3. Install oil pressure gauge.

4. Start the engine and allow it to reach normal

operating temperature.

5. Check oil pressure at 3000 RPM.

Oil Pressure: 2.0 ~ 5.0 Bar (28 ~ 70 psi)


Low Oil Pressure

Engine RPM Too Low

Wrong Viscosity or Diluted Oil

Low Oil Level

Broken Pressure Relief Spring

Missing Pressure Relief Plunger

Worn Bearings

Damaged Or Defective Oil Pump


High Oil Pressure

Wrong Viscosity Oil

Plugged Oil Galleries

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
