Hi guys,my 2001 civic lx has 170,000 miles and is running great but has started leaking oil. Oil pan is wet and oil is leaking behind the timing belt cover. Mechanic suggests starting with the oil pan $200 to do it. I got a feeling a seal under that timing cover is bad.... dont know what to start with. Car has only seen quaker state green bottle 5w20 all its life. Is high mileage worth a try. Im confused and dont want to get ripped off. I thank you for any advice you may have!
