05 minivan dripping too much oil. 150K mi. Drip is hanging from bottom of oil filter, but I cant see where its coming from. So I changed oil and filter, wiped everything clean. Snugged oil pan bolts which werent loose at all. Next day, drip, drip, drip...

Looks like I could replace oil pan gasket. Are these prone to leaking there or where else to look?

Tanks.
