I just bought a fully restored 1980 Series 3 88" with the diesel. It's a santana. The rear main seal is leaving about a 6 to 8" puddle of oil after driving. Longest trip has been about 20 miles around town. The shop that restored it claims it's a break in issue. I'm having trouble buying this argument. My dad and I restored a 73' series 3 in highschool. We had the motor rebuilt. Oil leaks eventually happened but 6-8 months and 100's of miles.

This is my first Land Rover with a diesel. Trying to educate myself on it. This oil leak doesn't seem like a break in issue. Anyone else with a similar issue? Very frustrating on a fresh restoration. This thing also sat in a shipping container for 4 months. I imported it out of Spain.

Thanks in advance!
