I've just purchased a 1992 Honda Accord LX (127,000) it does not leak any oil or any other kind of fluid. It seems to be running fine now. Just wondering with proper maintenance how long should I expect it to last. One more thing is there any way to know for sure it the original engine was replaced? Seller informed me that he replaced original engine 4 years ago, odometer read 265,000 miles. I appreciate any feedback, thank you.
