I have been chasing an oil leak in my 97 Honda Civic EX for the past year. Here's what I've done, where I am, would like your opinion.
97 Honda Civic EX with VTEC 4 cylinder developed oil leak at about 77,100 miles. Replaced O-ring, 77,122 miles, leak continues. Replaced Valve gasket cover and O-ring, 78,600 miles, leak continues. Replaced Rear Main Seal, 80,527 miles, leak continues, getting bigger. The leak is about 12" back from the front bumper, center. The car is NOT overheating, no other engine symptoms, but annoying having a constant leak. Not having to add oil. Latest diagnosis is that leak is coming from Head Gasket. Two estimates to fix, one says replace head gasket, at cost of 900.00, car in shop 3 to 4 days, the other says replace head gasket, cost about 600.00, 5 hours labor. I don't know who to believe anymore. The dealer says yes, possible head gasket leak, 1400.00 have car 4 to 5 days. Do you have any suggestions for me? I've spent close to 700.00 chasing this.
