Is it in any way possible a broken piston pin circlip can stop the oil circulation and cause a 100% drop of oil pressure when driving at 85 MPH?
(Edit) Some details:
- Freshly rebuilt MK3 engine; 4,000 miles driven
- Sudden loss of power driving at 80 - 90 MPH / 3,000 - 4,000 RPM
- Zero oil pressure on gauge at 80 - 90 MPH / 3,000 - 4,000 RPM
- After cooling down, the engine still ran (oil pressure was up, but lower than normal)
After pulling the engine:
- Piston/gudgeon pin circlip 2nd cylinder broken (see pictures)
- 2nd cylinder damaged
- All bearings worn (bearings at 6th cylinder show the most wear - 1st cylinder bearings - main and rod - look ok)
I'm trying to find out what happened, because I don't want to pay for a new rebuild.
