Thanx for your reply. The leak is at the rear core plug. It looks like there is a small hole in the center of the plug. The car is a 90 LX and the motor has over 150,000 miles on it and runs great. Is it common to see that many miles on a stock 5.0? Is there a "ballpark" mileage where I should start thinking about a rebuilt or crate motor replacement. I don't want to tear the heads off now if i'm gona have to pull the motor in a year or two. In that case, I would mabey just replace the motor now. I want to keep a stock 5.0 in the car. I've had the car sense 97 and besides regular maintenance have only had to replace an alternator, battery, radiator hoses, and a water pump.
Thanks again, Chas
