My 73 TR6 has developed a bad leak. Starts to leak after engine is running maybe 5 minutes. I have tried to locate the leak and it appears to come from the oil pan rear. I suppose it could be leaking from above, but I do not know if there is anything directly above the oil pan that could leak. I also may have scraped the oil pan leaving a elevated parking lot, so I suppose I could have bent the oil pan and broken the gasket seal. I plan to replace the oil pan gasket, but wanted to know if there were any other suggestions while I am ordering parts. Any suggestions on the oil leak?
