changed my oil this mornin' and notice there was a bunch of oil residue around and above the oil pan lip. I've also notice I've been goin' through about 1 quart every 1000 miles. this is a B18C1 with approx 50,000 miles. could it be burnin' oil already? or is it a leaking oil pan gasket??? HELP!!! Thanks in advance!
